Interference in Amateur Radio refers to unwanted signals that disrupt radio communication. This interference can reduce signal clarity, make contacts difficult, or completely block communication between amateur radio operators.
Radio Frequency Interference (RFI) is one of the most common problems in amateur radio. It often comes from man-made electronic devices such as phone chargers, computers, LED lights, televisions, and power supplies. These devices can produce continuous noise or buzzing sounds across radio bands.
Natural Interference also affects amateur radio operations. Lightning causes static noise, while solar activity can disrupt or enhance signals, especially on HF bands. Atmospheric conditions play a major role in how radio waves travel and how much noise is present.
Adjacent Channel Interference and Harmonics occur when signals spill over into nearby frequencies or when transmitters emit unwanted signals outside their assigned band. This is usually caused by poor filtering, excessive power, or improperly adjusted equipment.
Managing and Reducing Interference is an important responsibility for amateur radio operators. Techniques include proper grounding, using quality cables, installing filters, adding ferrite chokes, and ensuring transmitters produce clean signals.
Rules and Responsibilities in Amateur Radio require operators to avoid causing harmful interference, accept interference from other legal users, and correct any problems their station may cause. Cooperation among amateur radio operators helps identify and resolve interference issues effectively.
Options
Amateur radio interference can be reduced by controlling unwanted radio-frequency (RF) energy and improving how equipment handles it. One of the most effective methods is using ferrite chokes on coaxial cables, power leads, and the cables of affected devices. These chokes block RF from traveling along cables and significantly reduce interference.
Good grounding and bonding are also essential. The radio, power supply, and antenna system should be properly grounded, with metal parts bonded together using short, thick wires. A single, well-designed ground point helps prevent RF from spreading into household wiring and electronics.
The antenna system plays a major role in interference. A properly tuned antenna with low SWR reduces stray RF, and placing the antenna farther from buildings and electronics helps limit interference. Using baluns or common-mode chokes at the antenna feed point can further prevent RF from flowing back along the coax.
Interference can also be reduced by lowering transmit power to only what is necessary and by using filters such as low-pass or band-pass filters. Replacing or relocating noisy household electronics—like cheap power adapters or LED lights—can improve reception. Finally, using shielded cables, keeping wiring short, and changing frequency or band when needed can help minimize interference even further.
What about you?
I would love to hear what you have experienced and done about radio interference. Did you cause it? Did you experience it? What helped?

My original 6m radio – still works today
However, after many requests from the WIA to the DoTC back in 1989, it was agreed that this section of the 6m band could be used with some minor amendments.
VK5, VK6, VK8, VK9 & VK0
It was decided VK5, VK6, VK8, VK9 & VK0 stations may operate anywhere between 50 – 52 MHz provided there was no interference caused to the reception of Channel 0 transmissions up to a maximum of 400 watts.
VK2, VK3, VK4 & VK7 (eastern states)
Stations located in VK2, VK3, VK4 & VK7 are permitted to operate provided there was no interference caused to the reception of Channel 0 in the sub-band 50.05 – 50.20 MHz provided they are:
120 km from Channel 0 main television stations
60 km from Channel 0 translator stations
60 km from translator stations with Channel 0 inputs, and
They must only use emission modes of CW and SSB with a maximum of 100 watts.
VK1 ACT
Stations in VK1 can do the same as other eastern states but without the distance restrictions.
Today
Well that was back in 1989, today TV is all digital and the band is less restrictive now.
A short time ago I happened to make contact with Japan on 6m and also happened to be recording as well. You can watch the whole thing here:
I personally love 6m and the challenge of it. It works well locally and well when the band is open. But it can close suddenly without notice. Sometimes I’ve spoken long distances and either has received no signal strength at all, but a full S5 copy.
I also enjoy adjusting between vertical and horizontal polarisation.

I’ve heard a lot about dipole antennas, and I’ve heard a lot about long wire antennas also. I would say I’ve seen more dipoles than long wire antennas. So why is that? What is the difference between them? Which is better? If one is a clear winner, why does anyone build the other?
A dipole antenna is one of the simplest and most widely used antenna types. It consists of two equal-length conductive elements, each about a quarter wavelength long, making the total length approximately half a wavelength. The antenna is center-fed, meaning the feedline connects at the midpoint, where the impedance is around 73 ohms, allowing for easy matching with standard coaxial cables.
The radiation pattern of a dipole is broadside to the antenna, producing a figure-eight pattern in the horizontal plane. This means it radiates most strongly in directions perpendicular to the wire. The dipole provides a predictable, efficient, and balanced pattern, making it ideal for both HF and VHF communication systems where simplicity and reliability are important.
A long wire antenna, on the other hand, is a single conductive wire that is much longer than half a wavelength—often several wavelengths long. It is typically end-fed, with one end connected to the transmitter through an antenna tuner or matching network because the impedance is very high, often several hundred to several thousand ohms.
As the wire length increases, the radiation pattern of the long wire antenna becomes more directional and complex, forming multiple lobes with maximum radiation along the wire’s axis. This makes it useful for long-distance (DX)communication and applications where directional gain is advantageous.
In summary, the dipole antenna is a balanced, center-fed, half-wavelength antenna with a simple broadside pattern, while the long wire antenna is an unbalanced, end-fed, multi-wavelength antenna with a directional, multi-lobed pattern. Dipoles are preferred for efficient single-band operation, whereas long wire antennas are favored for multi-banduse and HF communications when space permits long installations.
So what is your experience with these antennas? Which one do you prefer and why? Have you made your own or have you bought it? Please leave your comments below.

On the 10-metre band, 28.490 is the unofficial calling frequency for Australia and New Zealand. This is interesting as the Band plans state it is 28.390 as the recommended intra-VK calling frequency.
That said, 28.490 is more recognised as the unofficial calling frequency down under.
Most amateurs down under will listen to 28.490 on ten metres and put out a call there, but then QSY to another frequency 10 or 20 kHz away either after making contact, or before contacting another station by announcing where you plan to go.
160 meters band is known as the “Gentlemen’s band”. It is right next to the AM commercial band, known as medium wave.
The 160-meter band is the radio frequencies between 1.8 and 2 MHz. For many decades it was the lowest radio frequency band allocated for use by amateur radio, before the 630 and 2200 meter bands were introduced.
Amateur operators often refer to the 160 meters as the Top Band because it was for some time.
The 160-meter band is the oldest amateur band. Antennas are usually huge in size due to the wavelength at this frequency, making the higher bands a lot easier to get into given they have shorter wavelengths, requiring smaller antennas. Small antennas lead to less space required and less cost.
During the day propagation is limited to local contacts, but long distance contacts are possible at night, especially around sunrise and sunset.
How it started for me
The hobby started for me on Medium Wave, where I was shocked to receive long distance AM radio signals from interstate radio stations. The distances were huge, across countries if I was in Europe. As a kid I loved listening to interstate radio and sometimes phoned them to let them know. They were shocked I could hear them and often mentioned me by name soon after my phone call.
My Antenna’s
I’ve tried several antennas on this band. They include:
A horizontal dipole antenna. This worked really well though it was huge. The problem I had with this antenna was most people in my area use vertical antennas so they couldn’t hear me well.
A horizontal long wire antenna. This antenna was also huge, and also not vertical. So it worked well for close contacts, but not as good if I tried to contact a few suburbs away.
An inverted L antenna. This worked the best as my local contacts used vertical antennas. I tried to get the vertical part as high and as long as I could before doing that horizontal part. Given the length of the wire needed, most of the wire was still horizontal, but at least the first but was vertical. Though the secret to this antenna was the ground wires. I started with two of them and ran one around the house about 2 feet from the ground. The other was around the fence. I will put at least two more out which should also help improve things.
Summary
Getting on 160m was a bit of a challenge due to the wavelength. I could be heard on SSB, but AM was the biggest challenge. With AM, my radios would put out less watts so I had to rely more on my antenna.
Below is a small video of my 160m antenna and how I made the inverted L. With amateur radio, there will always be improvements and I am sure this setup isn’t the best, but it is a start and I learned what I could from the other amateurs who had already mastered this band.
Below is an extended video which goes into a bit more detail of how and why I did what I did. I adjusted all my HF antennas to make this 160m antenna work while not upsetting any of the other bands.
As I mentioned in both videos, I am not a professional, but an amateur radio operator and as keen to learn as anyone else. If you have any thoughts on this, I would value them in the comments below. It will not only help me, but others reading this. So don’t forget to have a look at what others have to say.
160m Coffee Break Net
Each weekday in Melbourne, there is a 160m Coffee Break Net. This net is a bit of a challenge to get onto because you must:
Have a full licence
Have a vertical antenna (which is the biggest challenge for 160m)
Have a radio that does AM, and puts a few watts out
As you can see above, I was able to make a 160m vertical antenna, so once I got this working, I was on the air! Many people try their dipole antenna, as did I at first, but on AM, it just doesn’t go far, and since everyone on the net is vertically polarised, they couldn’t hear me. I saw this as a challenge, and one worth trying.
Prior to 1989, it was illegal to operate between 50 MHz and 52 MHz in Australia. It was a real pain as that was where all the action was when the band opened up.

The Anytone AT-778UV is a dual-band VHF/UHF mobile transceiver designed for amateur radio operators. It operates on the 136–174 MHz (VHF) and 400–490 MHz (UHF) bands, offering reliable two-way communication for both ham radio and commercial use (depending on firmware version).
Power Output
This transceiver provides selectable power levels — typically 25 W, 15 W, and 5 W. These adjustable settings allow users to manage power efficiency, heat, and battery draw when operating from a 12 V vehicle power system.
Channel Capacity
The AT-778UV supports 200–250 programmable memory channels, making it versatile for storing repeaters, simplex frequencies, and emergency channels. Channel naming and scanning functions simplify navigation during mobile operation.
Display and Design
It features a color TFT LCD display with 180-degree rotation, allowing flexible mounting in various vehicles. The metal chassis and integrated cooling system improve durability and heat dissipation, especially during extended transmission periods.
Signaling and Features
Key functions include CTCSS/DCS, DTMF encoding/decoding, 2-tone/5-tone signaling, and ANI/PTT ID. These options make it suitable for both amateur repeaters and commercial communication networks, enhancing identification and access control.
Software and Programming
Users often mention programming challenges, particularly with USB cable drivers and COM port errors on newer Windows systems. The Anytone programming software or CHIRP can be used, but compatibility varies depending on firmware version.
Dual Watch
Some people hate Dual Watch, but this is mainly because they do not understand it. I think this radio does dual watch better than most and the reason is:
There is a sperate signal meter per zone making it clear which one you are listening to. I wish all radio’s did this.
When Dual Watch is on, you can see both the A band and B band, but when it is off, you can only see one band on the screen. Again, I wish all radio’s did this.
It says clearly on the bottom of the screen if you are on A or B band. I really wish all radio’s did this.
If you are not sure what Dual watch is, then have a look at this video. It is great when you are listening, but not talking to anyone and the repeaters are a bit quiet.
I had a few mic gain issues my my radio. Some have drilled holes in the microphone to fix this, but before you do this, it might pay to watch the following video.
Most owners praise its value for money, build quality, and audio clarity. Common complaints include menu complexity, occasional freezing, and scan delays. Overall, it’s regarded as a solid budget mobile ham radio with a rich feature set.
I do love how you can change the display on this radio and re-program the buttons. The following video with help you with this and show you what I mean.
There are several DMR networks around the world, and more and more start all the time. The Australian DMR network currently covers the entire country and is for Australian residents only.
It can often be hard to find which DMR repeaters are online, offline and where they are, especially if you travel a bit like me.
Here is a few links that may be of some use. Please let me know if these links no longer work.
If you want to check the status of these above repeaters, have a look at this page. It shows which ones are currently online, or offline.
Online repeater map is a great page showing all repeaters around Australia. It is well worth the look at if you are traveling or are going to be in Australia. https://www.onlinerepeatermap.com/
Another way is via the DMR database. If you put the start of the repeater call sign in the middle repeater section it will list the repeaters in your area. For example, all repeaters in my area start with VK3, so I put in VK3 in the middle callsign box and selected begins with and got a list of registered repeaters. This will work all over the world. https://www.radioid.net/database/search#!
Further Reading
Enjoyed what you read, here is some more interesting articles on this site you may enjoy.
Have you ever tried Band Stacking before? This is where you have three options per band every time you go to that band. For example, you may have one set up on SSB, one on CW and another on Data, all on the same band. You can easily switch between them all.
For example, if you are on 20 metres, press band and 14 again, and if band stacking is on, it will keep you on 20 metres but to the different stack. This different stack could have a different mode. You usually have three per band.
Have a look at the video for more on how to use it and turn it on:
The first thing I noticed after receiving the radio was the size of the radio. It is small yet not to small that it is hard to use. It fits comfortably in your hand.
Not only is it physically small, the price is amazingly small also. How I would have loved to have this radio when I started in the hobby 35 years ago!
Saying that, I see this as a great entry level budget radio. Or a small radio for camping or in the car rather than putting an expensive radio in.
The GT-5R PRO is an enhanced version of the classic GT-5R, capable of receiving a wider range of frequency bands including UHF, VHF, FM, NOAA, Airband, 1.25M, and 1M.
I was easily able to program the radio via the keypad putting in my local repeaters with the required offset and tone squelch. But it was even easier to program it via Chirp Next and I have a video on how to do that.
It is a 5 watt radio complete with VOX if you want to go hands free.
The GT-5R PRO is fully compatible with the UV-5R’s accessories. Such as the car charger, speaker mic, ear piece, antennas plus more.
The GT-5R Pro comes in a standard single-unit version as well as a kit version that includes a long antenna and programming cable. I got the kit version, so be shore when purchasing you know if you want the kit or the single unit version.
Contents • Radio • Fast desktop charger • Antenna • Long antenna • Li-lon battery pack • Wall adapter • Belt clip
It supports UHF VHF dual band transmission and a wide range of reception frequency bands, including 136-174MHz, 400-520MHz, 76-108MHz, 108-136MHz, 200-260MHz, 350-390MHz, and NOAA weather channels.

Testing
I quickly made some contacts on both 2m and 70cm and both said my audio was great. I swapped antennas halfway though a conversation and found the small antenna better but that was just for one repeater. I plan on doing more tests in the coming weeks.
Programming Tip
Did you know you can program these radios via Chirp? Here is a great tip you may like with chirp.
When I received the radio, I was stunned at the price and thought I can’t really go wrong here. I didn’t check the hypnotics but everything else I checked worked well.
It is a Tri-Band radio which includes UHF, VHF, 1.25M, and multi-band reception (VHF, UHF, FM, Airband, 1.25M, 1M, NOAA).
It does a huge 10W which isn’t bad for a hand held. But also does 10W, 7W, and 4W output.
It has several ways to charge it. The 2500mAh rechargeable battery lasts a long time even on high power, and doesn’t take long to charge either. You can recharge via the new Type-C port cable, or recharge using the included desktop charger.
While the radio does come with its own software, I love it is Chirp Programmable. It means you can continue to use software you are familiar with and import repeaters from repeaterbook for example.
Using the radio while fishing
The radio has a 1.77-inch LCD display and a robust 2500mAh rechargeable battery
You can keep your conversations private using the scramble function, but just check first you can use this feature. I noticed it works well when signal levels are high.
Some of the things I didn’t like
The hand speaker mic felt a bit cheap as mine had a switch that made a lot of noise when you shook it. That said, it worked fine and no one said I sounded any different. It also has a nice adjustable clip that you can rotate.
You could say every amateur radio operator knows about the Baofeng if they have been around long enough. Most have held one of their radios and lots have at least one. They have made a huge amount of radios.
According to their website, they have been around fifty years now. However other information I found contradicts this.
Owning a R&D team with 50 years experience in the field of wireless communication. Having launched the Baofeng series of wireless walkie-talkies and related ancillary products.
But how big are they? Do they just build radios and then tweak them to launch another one or are they bigger than that?
Again, according to their website:
Total employees over 1500+. Our factory locates in Changfu Industrial Zone, XIamei of Nan’an, Quanzhou, Fujian province, China.
So what does Baofeng mean in English?

Baofeng Radio Information
After a bit of research, this is what I found.
Baofeng, a Chinese manufacturer, was founded in 2001 by Mr. Wang Jinding founded Baoan Electronics Co., Ltd. in Nan’an City, Fujian Province in Nan’an City, Fujian Province. In 2017, Fujian Nan’an Baofeng Electronics Co., Ltd. changed its name to Fujian Baofeng Electronics Co., Ltd.
It gained prominence with its Baofeng UV-5R dual-band radio, which became popular for its affordability and features, but also faced regulatory scrutiny due to potential frequency interference.
Fujian Baofeng Electronics Co., Ltd. was founded in 2001 as a high-tech enterprise focused on research, development, production, and sales of radios.
The Baofeng UV-5R, a dual-band radio, became a global sensation in 2012 due to its affordability and features, particularly its ability to operate on both VHF and UHF bands.
However, the UV-5R, and other similar radios, faced regulatory issues in countries like Switzerland, Germany, Poland, and South Africa, due to concerns about frequency interference and the lack of certification in some regions. In the United States, the FCC cited Baofeng for illegally marketing the UV-5R, which was “capable of operating outside the scope of its equipment authorization”. The UV-5R served as a basis for numerous other models, with vendors able to create private-labeled versions, according to CHIRP.
The German Federal Network Agency banned the UV-5R because it dampens harmonics poorly, potentially disturbing other users, and the Independent Communications Authority of South Africa issued a ban after finding the UV-5R to be causing radio frequency interference and for having continuous tuning capabilities, a feature that would require an operator obtain a Frequency allocation license before purchasing or using the device.
Baofeng Models
This website I think only shows a fraction of the radios Baofeng have made and sold. For example a Pro version will be very similar to the original version but comes with so many more things, it is almost a new radio.
In my experience, you either love them starting at their cost, or hate them. It’s well known that some of cheap in price and quality, but this is perhaps the earlier models. If you love them, then they will bread like rabbits, if you hate them and own one, it will probably be sitting at the back of the draw or behind a box somewhere out of site.
There are so many models available now. So if you are wanting a hand held radio and on a budget, do your homework well. Just because it may be the latest model, doesn’t mean it has everything all the other models have.
Baofeng Radios Reviewed
Below are the Baofeng radios I have reviewed on YouTube. Hope you enjoy them.
I recently got my hands on a new Baofeng UV-17R Plus Series radio. It didn’t take long at all to arrive and was not expensive at all. People these days pay more for a UHF CB radio than a radio that does all this can do.
My last Baofeng radio is a GT-3TP which you can still purchase new. It also works well and have always received good reports from it.
The UV-17R Plus is an upgraded version of the UV-17R handheld with the following: extras
an expanded receiving frequency band (encompassing aviation and police bands in the US),
an extended battery boost from 1800mAh to 2500mAh (that works out to about 40% more charge),
a quick USB-C charging plug and cord, and
it also has a new voice scrambler function.
Some of the things I liked with the new UV-17R Plus Series includes:
The look and feel of the radio. This includes the bright display, feel and position of the buttons, large LED lights, and easy antenna swapping as the area is wide. I also like the speaker behind the keypad, this saves room and is an area you never cover with your hand either. The text on the display is far easier to read than older models inside and in the sunshine.
The new USB-C charging is so much better. You don’t have to bring a charging cradle anymore when you leave the house, and can even charge it in the car easily.
Customising DTMF is easy via the # key. It will also search for a used frequency then will display what CTCSS or DTMF is used. This can quickly be saved as a channel also.
Secure conversations – I couldn’t test this as I only have one radio, but agree this is a good feature. However, I did talk on it myself and my digital scanner couldn’t decode it.
The weather feature would be good if you are in a country that uses it. Australia does not. I could see this being a great radio in an emergency with the LED lights.
The user manual is well put together and entirely in English. A PDF version is available online also.
The radio can be programmed directly, or your PC via several different software options. I have done a video on this below if you want to see this.
It comes with an 18-month warranty.
Here is a video where I unbox the radio and show what is included in the package. If it is helpful to you, please press the like button.
Below is another video showing some of the features that the radio has. While I don’t show you them all in action, it will at least give you an idea of how the radio works.

This is a great radio for the price. It does far more than I thought it would and I am sure will get a lot of use out of it. I was initially concerned it may be hard to use because of the price, however, was pleasantly surprised how easy it was to program.
Below is a video I did showing you how to program the radio via a PC using Chirp-Next.

I’ve heard several amateur radio operators say they are running a Barefoot setup. But what does it mean?
It has nothing to do with what is or is not on your feet. But simply means transmitting without an amplifier.
While power helps, the best thing you can do to fix your signal is your antenna. It doesn’t matter how much power you put out if your antenna is facing the wrong way, or not tuned in correctly. If you are struggling to be heard and sure your radio is set up correctly, I would look at the antenna first.
Some operators think there are two types of radio setups, thoughts with amplifiers, and thoughts without. Some see using an amplifier as cheating. I am not sure I would go that far, but if you are putting out a thousand watts, then yes people will hear you, but this doesn’t help you hear them when they put out 100 watts.
So, are you a barefoot operator or not? Perhaps you are on some bands or radios, but not on others?

Everyone that has been into radio for a while will know the brand Kenwood. And most know Kenwood isn’t only into Amateur radio, they are bigger than that, and have been also. But are you sure it started in Japan? What else do they make? How big are they today? And what does the name Kenwood stand for?
Kenwood is a Japanese brand of consumer electronics.
In December 1946, Kenwood was established as the Kasuga Radio Co. Ltd. in Komagane, Nagano Prefecture, Japan
In 1958 the company put its first amateur radio on sale.
In 1960, the company was renamed Trio Corporation.
In 1962 they launched the industry’s first transistor amplifier
In 1963, the company established its first overseas office in Los Angeles County, California, United States. It began to sell overseas.
During the 1960s, Trio’s products were rebranded and sold by the Lafayette Radio Company, which focused on citizens band (CB) radio.
The name Kenwood was invented by Kasuga as a combination of
“Ken” which is a name common to Japan and North America and was considered acceptable to American consumers, and
“Wood” which was referring to the material wood, as well as suggesting a relation to Hollywood, California.
In 1966 they introduced the fully transistorised audio products for the first time in the industry.
In 1969 the TR-7100 2m amateur radio for the car goes on sale.
In 1979 the company established the first production overseas in Singapore.
In 1986, Trio acquired Kenwood and subsequently rebranded itself as Kenwood Corporation. This was because Kenwood was more widely recognised than Trio.
In 1991 Kenwood signs an official supply contract with McLearen to provide wireless radio equipment for the F1 Championship
In 1992 they produced their first car navigation system
In 1995, the Mir Space Station carries Kenwood’s amateur wireless equipment.
In 1996 the company was renamed from Tri-Kenwood to Kenwood which coincided with the company’s 50th anniversary.
In 1997 Kenwood made Japan’s first car mounted DAB receivers.
In 2001, Kenwood releases its first digital transceiver operating on P25.
In 2002 they withdrew from the test and measuring equipment business
In 2005, Kenwood joins up with Icom to jointly research the standardisation of technical specifications for digital wireless radio equipment (NXDN).
Since October 2008, Kenwood has been owned by JVC-Kenwood because of a merger between Kenwood Corporation and JVC.
Kenwood has manufactured electronic equipment such as
AM/FM stereo receivers,
cassette tape decks/recorders,
amateur radio (ham radio) equipment,
radios,
televisions,
mobile phones,
speakers, and
other consumer electronics.
Radio
Kenwood has produced two-way radios for a variety of communications standards, including:
wireless DECT intercom systems,
the radio frequency PMR446 and its digital counterpart DPMR446,
DPMR, the Project 25 standards suite,
DMR and
NXDN
Kenwood Today
The Kenwood radio catalogue of today shows what radios they are selling now.
These include
hand held radios that are single, dual and tri band radios
Mobile dual band radios some complete with remote heads. Again single and dual band radios.
All band HF radios some small, some are large and covered in buttons and options
And all band HF, VHF and UHF radios
Today their website shows they are into
Car electronics including digital technology and enhanced in-car comfort and navigation. They have some very cool photos of their motorsports equipment on their website. https://www.kenwood.com/e/motorsports/
Communications using digital technology handheld and base stations, from Professional through to CB radios

Kenwood Logo
So, what do you know about the Kenwood logo?
If you go to their smart website, you can see the red triangle in the logo isn’t there to just look pretty.
The red triangle is the core part of their logo and represents the three values of the Kenwood brand.
Advanced
High Quality
Sharpness
But it doesn’t stop there, the four corners of the W stands for
Precision
Innovation
Emotion
Communication
Your thoughts
So, what do you think, does Kenwood measure up to your expectations? Tell me in the comments below.
What Kenwood radios did, or do you have? What did you think of it? I’d love to know.
For me, I have had a few but still use occasionally the Kenwood TS-120V. It was one of my first HF radio’s and I bought it before the internet was available. I though it was the 100W version, but quickly found out it is not. That said, I enjoy using it every now and then.
So, what did what you learn? I know I learnt a bit. I’m keen to hear what you learnt today.
How many of the Kenwood Radios do you know that I have shown in this video?
If you enjoyed that read, then you may enjoy some of these, including my post on Yaesu which is just as informative.

HamClock has always fascinated me, as it seems such an amazing program specifically set up for Amateur Radio. I have seen countless videos on it but the draw back was always needing to have a Raspberry Pi. While I am not afraid to get one, and learn how to use it, I just didn’t feel like taking the plunge into that world just yet. Though I think that world is about to come, and I will end up regretting not doing it sooner!
So, what is HamClock?
Glad you asked. According to their website (https://www.clearskyinstitute.com/ham/HamClock/) HamClock is a kiosk-style application that provides real time space weather, radio propagation models, operating events and other information particularly useful to the radio amateur.
It is designed to provide ham radio enthusiasts with real-time information about the sun’s position, ionospheric conditions, and DX cluster spots. HamClock is an open source application which is a tool for the shack providing live up to date information all on one screen. It was originally written by Elwood Downey WB0OEW.
HamClock displays a map showing the sun’s position, illumination (daylight/darkness), and the “grey line” (the transition between day and night). This information is crucial for understanding propagation conditions, as the grey line is often a prime time for DX (long-distance) communication.
Usually it needs to be installed on Quadra or lynix, but I have recently found out you can install it on Windows.
Installing HamClock on Windows
Guess what, this is possible, and may feel overwhelming at first, but after following the video below, I was able to do it in real time along with this video. I was shocked how easy it was and super surprised I had not done this earlier.
Before doing the video, I suggest you read all the points below it as there were a couple of things I changed.
The video starts with music, but just do what it says. Then the author will talk you through the steps after the initial install.
The bit I got stuck on was setting up Cluster in HamClock. This is about 12:50 into the video, perhaps it was because I had an updated version of HamClock since the above video was done. So, instead, I put in the following settings:
Setting Up HamClock
There are countless ways to set up HamClock. As a starting point, I stuck with the video above as he shows you how to from 13:30. Below is a link to that point in the above video.
This video below is from a friend who also shows you in great detail how to set up your HamClock to get the most of it. Some things are slightly different, but after seeing this, you can have an informed choice.
I found this video below very good also, as it goes into detail regarding the map in HamClock. As you will see it is done by the same person. He talks about the maps and how to customise it easily.
After a Windows Reboot
When you next do a windows reboot, you will need to restart HamClock. To do this, open a CMD window by typing CMD in the windows search menu.
Then type in :
wsl sudo hamclock &
and put in your password you made for lynx and you should be able to open it again. Make sure you do n ot close the comand screen until you are finished.
Summary
Below is what my HamClock looks like. I like the background “terrain” map as well as the night and day showing on the map. I would value your thoughts though, as I know I am about the last one to finally get onto HamClock.
With all of these tools, we should remember propagation shown is using data, but the rest of it is predictions based on knowledge.
If these propagation tools show there isn’t anything happening, always give it a try anyway. You never know without trying. You may be higher than other stations, or put out more power. You might just get an opening before other stations.
All the propagation websites are a summary of conditions recorded and sent in. HamClock is a good tool, it looks good, and gives you a lot of information on the one screen. You can adjust it easily also.
Please tell me your thoughts, and what you think. Do you use it? Perhaps you use it differently and have some advice for me and other readers. Hope you enjoyed the read.

Have you heard of a flowerpot antenna? I hadn’t until recently, and I enjoy gardening also. But this antenna has nothing to do with gardening apart from why it was named flowerpot and it will probably end up either on your roof or garden.
A good friend of mine put me onto it as I was having trouble on 6m. A small group of us think 6m is under-utilised so we all get on their and chat for a while either on AM or SSB.
My antenna worked reasonably well, but they suggested I build my own using the flowerpot method. Given I’m always up for learning something new, I couldn’t resist.
The best but about the antenna is it is extremely cheap to make, easy to put together and the antenna works really well.
You can make a flowerpot antenna for either 6m, 2m or 70cm. You can hang it in a tree if you wish, in a pvc pipe like I did, or using a pole or something else.
There were only two parts I needed, everything else I already had. But if I had bought everything, it would have cost me I total about $15. Not bad for a great antenna and one you can say you built yourself.
All I needed to buy was the pvc pole, which is optional and a slightly wider pipe to make the coil on I already had the RG58 coax, and it even had a pl259 plug on it!
My flowerpot antenna
Items I purchased included: PVC Pipe. Make sure you give it a shake in the store before buying. If it is too flexible then it may bend and snap in the wind. But you don’t want it to heavy either.

Why does a radio need a cup holder? I agree it’s a bit odd. But this isn’t a product that involves a cup. Rather it uses a cup holder.
Almost every car now has a cup holder, but they are all different sizes and locations in the car. Some are large for bottles, others are small for a small coffee. Some are in the door, others are in the centre console of the car, while others are half under the dashboard. Unless it is the same model car, they all seem to be a bit different.
One thing I’ve noticed is a cup holder is never the same size as a hand held radio. What are they thinking! As a radio operator you would think they would build cars to house our radios! Seriously though, cars hardly have any space for much extra.
My current car has almost no space to mount a radio at all. I have a radio that has all the controls on the microphone because of this. I also have a hand held radio that sits on the center console between the two front seats. But this is far from ideal as if I have to brake suddenly, the radio goes flying. Not ideal!
I saw this cup holder radio bracket that is adjustable and fits into a cup holder. It is very adjustable and fits sturdily into a cup or bottle holder.
At the top of the swivel, you can attach a fixture to attach any hand held radio via its belt clip or attach a small remote head radio via its bracket.
Once it is all secured, it works well. Now I have a hand held radio in my car, that doesn’t move around the car. It’s legal and sturdy plus I can see the screen when driving.
The other advantage of this device, apart from how easy it is to install and how versatile it is, was how easy it is to remove. So if I’m in the car for the day, or a year, I can take it out when I am done and return the car the way I found it.
Installing
Here are some quick steps how to install this device.
After unpacking the box, get the RH1 cup holder.
Attach the Angle-Adjusted Connector to the top.
Attach the Handheld radio holder to the Angle Adjustment Connector. Alternatively, you can attach your radio attachment plate to the Angle Adjustment Connector if using a remote head radio or light weight radio.
Place the RH1 in your cup holder and twist so it expands to a firm fit in the car.
Adjust all the available angles from the bottom up to your desired location, then tighten each angle once set. Make sure it does not obstruct you driving the car or your view.

This page is just a help to friends I have spoke to who are interested in upgrading the Radioditty GD-77 to the OpenGD77 software. This is not my work, however I really do appreciate Roger and his team have done to put this together. I claim no responsibility if it breaks your radio, however I have not hear this happen now in some time. I am not an expert at all with OpenGD77, I have just put this together to help people who have asked me how to do it.…
Updating the firmware on the GD-77 can be daunting, as you can easily “brick” your radio. So be extremely careful. Make sure you understand why you are updating your firmware first. Since there is the option of “Bricking”…

There are lots of duel band antennas available, but most required extra mounting brackets. These brackets often restrict you as to where you can mount the antenna on your car.
One of my first mobile antennas for the car was a magnet mount antenna. I used it on the family car before I even had a driver’s license. I could mount it right in the centre of the roof, giving me excellent reflection from the car.
It was also easy to remove when I wasn’t in the car, or if we had to park the car in a low garage.
The dual band antenna is easy to put together on the magnetic base, and heavy-duty cable with PL-259 connector.
It comes with a very strong magnetic base that measures 91mm /3.6’’ across. After using it on the car, I doubt any wind or speed will blow it off the car like my older smaller magnet base antennas.
