Baofeng UV-5R Mini

The Baofeng UV-5R Mini handheld radio is a popular and affordable dual-band amateur radio transceiver widely used by beginners and experienced ham radio operators. Designed as a compact version of the original UV-5R, this small and lightweight VHF/UHF walkie talkie offers solid performance for everyday communication, making it a common choice for those getting started in amateur radio (ham radio).

The UV-5R Mini operates on both VHF (136–174 MHz) and UHF (400–520 MHz) frequencies, supporting communication on the 2 metre and 70 centimetre amateur bands. With a typical output power of around 5 watts, it is suitable for short to medium range communication, including simplex operation and repeater use. Many versions include features such as CTCSS and DCS tones, allowing access to repeaters and private channel setups.

This compact handheld radio includes a range of useful functions, such as 128 memory channels, a built-in FM broadcast radio receiver, VOX hands-free operation, and a small LED flashlight. Some newer UV-5R Mini models also support USB-C charging and Bluetooth programming, making them easier to configure using smartphone apps or software like CHIRP programming software on a computer.

Compared to the standard UV-5R, the Mini version is more portable and pocket-friendly, though it often comes with a smaller battery and display. Despite the reduced size, the RF performance is generally similar, making it a convenient option for portable use, hiking, or as a backup two-way radio.

The Baofeng UV-5R Mini is known for being a budget-friendly handheld transceiver, which is one of its biggest advantages. It provides access to amateur radio communication, repeater networks, and frequency scanning at a very low cost.

In Australia, the UV-5R Mini can be used legally for listening to radio frequencies, but transmitting requires an amateur radio licence issued by the ACMA. It is important to note that this radio is not approved for UHF CB (477 MHz) or commercial radio use, which are governed by different regulations.

In real-world use, the Baofeng UV-5R Mini typically achieves a range of 1 to 3 kilometres in urban environments, and up to 5 to 10 kilometres or more when using repeaters or operating from elevated locations. Performance can be significantly improved by upgrading to a better antenna or connecting the radio to an external base antenna.

Overall, the Baofeng UV-5R Mini dual-band handheld radio is a great entry-level option for those interested in ham radio communication, repeater operation, and portable VHF/UHF use. It is especially useful as a backup radio or learning tool.

The 6-Meter Amateur Radio Band

What Is the 6m Band?

The 6-meter band, spanning roughly 50–54 MHz, is a section of the VHF spectrum assigned to amateur radio operators.

Its wavelength is six meters, and its position between HF and VHF makes it behave like a mix of both services.

Why It’s Called the “Magic Band”

6 meters has an almost unpredictable personality.

Sometimes it acts like a local VHF band; other times it opens up suddenly and supports long-distance DX like HF.

Because of these rapid and surprising changes, operators refer to it as the Magic Band.

Contacts I had across to Europe

Propagation Characteristics

6 meters supports a wide range of radio propagation mechanisms:

Sporadic-E

Dense patches of ionization in the E-layer

Allows contacts hundreds to thousands of kilometers away

Most common from late spring through summer and again in winter

F-Layer / F2 Propagation

Appears during strong solar activity

Enables global, long-haul communication

Can keep the band open for long stretches

Tropospheric Enhancement

Weather-related bending in the lower atmosphere

Extends VHF-range signals over much longer distances

Meteor Scatter

Radio waves reflect off meteor trails

Excellent during meteor showers

Modern digital modes—especially MSK144—dominate this technique

Auroral Propagation

Signals scatter from auroral activity

Produces a very distinct, rough sound

Common at northern latitudes

Trans-Equatorial Propagation (TEP)

Occurs near the geomagnetic equator

Allows north–south DX paths across continents

Modes of Operation

6 meters accommodates virtually every common amateur mode

Weak-Signal & DX

SSB, CW

Digital

FT8 (primary mode for most openings)

FT4, JT65

MSK144 (meteor scatter)

FM

Simplex and repeater use in certain regions

AM

Niche but still used by some hobbyists

Equipment and Antennas

Radio

Many modern HF transceivers include the 6-meter band. Examples include:

Icom IC-7300

Yaesu FT-991A

Icom IC-705

Dedicated 6-meter rigs and transverters are also popular among weak-signal operators.

Antennas

6-meter antennas are small enough to install easily yet large enough to perform well.

Common options:

Dipoles

Verticals (good for FM)

Yagis (excellent for DX)

Moxons

Loops

End-fed half waves

Even a small Yagi can work impressive DX during an opening.

Seasonal and Solar Patterns

May–August: Prime Sporadic-E season

December–January: Smaller Es season

Active solar years: Best chances for worldwide F2 propagation

Meteor showers: Ideal for MSK144 activity

What Makes 6 Meters Appealing

Sudden, exciting band openings

Possibility of worldwide communication with small antennas

Plenty of room for experimentation

A wide variety of propagation modes

Generally less crowded than HF

The band blends scientific curiosity, operating skill, and pure luck — which is exactly why many operators love it.

Example

I love 6m when it is active. But I also love 6m when it isn’t open as a few of us use it to chat on it.

The Japanese love 6m. They seem to use it all year perhaps because they don’t need the band to be open to use it and talk across their country.

Below is a video where the band was open for a few minutes. Only a few contacts were made and I happen to be one of them.

After my contact, the bad suddenly closed, making this contact all the more special.

Yaesu FT-620

The Yaesu FT-620 (and its updated version, the FT-620B) is a vintage amateur radio transceiver designed specifically for the 6-meter band (50–54 MHz). Produced in the 1970s, it offers support for AM, CW, and SSB (USB/LSB) modes, making it a versatile rig for its time, especially during the era when 6 meters was gaining popularity for both local and DX communications. It was part of Yaesu’s early generation of VHF monoband rigs, built with a solid metal chassis and analog controls, reflecting the rugged, durable engineering of the period.

In terms of performance, the FT-620 delivers approximately 20 watts PEP on SSB and CW, and around 4–8 watts on AM. Receiver sensitivity is quite good for a rig of its era, typically around 0.5 µV for 10 dB S/N in SSB/CW modes. The transceiver divides the 6-meter band into multiple segments using a bandswitch, and offers decent selectivity for SSB and CW operation. It can be powered from AC mains or 12–14 VDC, providing some flexibility for mobile or backup use. However, it lacks FM capability, which limits its use with modern 6m FM repeaters or simplex FM operations.

While the FT-620 is highly regarded for its build quality and straightforward analog operation, it does show its age. There’s no digital display, DSP, or modern filtering, and some units may require refurbishment—such as replacing aging capacitors or realigning circuits for optimal performance. Its bulk and weight (~8 kg) also make it less convenient for portable use. Nonetheless, for those interested in classic radios or operating 6 meters on SSB/CW, it remains a capable and enjoyable rig, particularly when paired with a good antenna.

Overall, the FT-620 is best suited to enthusiasts who appreciate vintage gear and are willing to maintain it. It still holds practical value today in the right hands—especially for those focused on SSB or CW operation during band openings. While it won’t compete with modern rigs in terms of features or integration, its simplicity, durability, and vintage charm continue to appeal to collectors and seasoned hams alike.

See my video below where I fire it up and give it a test.

See me fire up this old girl

Remote testing Antennas

I’ve always wanted to take the radio with me while on holidays and I always do. However I’ve always been limited to 2m and 70cm including local repeaters and digital work.

Our family enjoy holidays all over Australia into some of the most remote places without water, power or any mobile signal. Sometimes this can last week’s at a time.

If your keen to learn more about our travels around Australia and learn more, please let me know.

Most of these remote locations means limited activity on 2m or 70cm as there are no repeaters for days!

Because of this remoteness, there are several outback radio networks we can join or listen to. They make quite interesting listening.

However, when on holidays, we amateurs don’t want to just listen, we want to be part of the action! And HF is the next best thing.

I’m currently on holiday in the Victorian high country, also known as “The Man from Snowy River” country. It is rugged, beautiful and high. So up here I can actually can receive several 2m and 70cm repeaters, but this is a good test for HF work.

High up on Mount Buffalo

With me, I brought a battery pack, that has a 12 volt lithium battery which we run our camping fridge off.  I now run my HF gear off it!

I also brought my new QT-80 radio, which is small in size yet puts out 80 watts.  I have placed a video below on this radio if you are not familiar with it.

I used a magnet mount antenna base as the car I was using is not mine. This mount sticks to the car like glue, but also comes off on demand so you can adjust the antenna as required.

I brought two antennas to test.  The first one was the HF-008 antenna that covers more bands than the QT80.  I have a video on both these below for you if you are not familiar with it.

I also brought the new CBL-561 HF antenna so I could compare the two antennas. This antenna can be used while mobile unlike the HF-008 antenna. I have another video for you to show you that antenna below:

Before leaving home, I went to the hardware store and bought two lengths of pipe with caps that could safely store each antenna. I could then almost throw them in the boot of the car and not be worried about them being damaged or caught on something as I pulled them out of the boot.

Hot Tip

The funny thing was, while on holidays, I forgot to bring a measuring tape to adjust the antenna. Fortunately one of my children had a ruler with them so I was able to mark measurements down the side of the tube with a sharpie.

I also wrote down next to the measurements the lengths Radioddity recommended and then as I tuned in the antenna myself with the lowest SWR, I marked the pipe to my best measurements which were very close to the same as Radioddity.

This Tip I am sure will be very useful going forward when I’m out in the Australian outback or somewhere that I have no ruler!

Results

Both antennas fitted the same magnetic base which made this setup work well.

On testing both antennas using the same frequency to the same long distance contact, I and they couldn’t tell the difference between us. I found both antennas easy to tune in and get the SWA right down before making any contacts.

I then tried again from the top of Mount Buffalo, one of our highest mountains and got the same results where both myself and the contacts I spoke to didn’t know I had even changed the antenna.

There are differences between the antennas though which may help you decide which antenna is right for you.

Compare Antennas

HF-008

This antenna covers a lot of HF bands, as covered in the video above. However it cannot be used while mobile, mainly due to the jumper cable. It is a great antenna and can be used with a radio that puts out a lot more watts than the small QT-80 radio I used.

CBL-561

The CBL-561R antenna does not cover as many HF bands as the HF-008 does, but if you are using the bands it does cover, then this antenna might be good for you. One big advantage to this antenna is that it can be used while mobile, not just stationary.

Both antennas will need adjusting if you switch bands or switch from one end of the band to another. So setting the antenna to a permanent mount on the car on the top of the roof where it ends up out of reach, then you may want to rethink this. I found the magnet mount ideal, as you can still have it on the highest point of the car and access it easily.

Another option I also use is a bull bar mount that I use on my 4×4.

I’d encourage you to watch my video below as it explains what I discovered.

Remember the old saying Hight is Might and going portable gives you an opportunity to test this theory.

Cables, how to organise trick

A simple tip that you may always use after reading this.

Often our shacks end up with cables everywhere. It can be a little hard to remember what cable goes where after a few years. It all starts well but as the equipment grows, so do the cables. I have trouble with the power cords in the power boards and what each plug is!

My shack originally only had one cable that went out that hole, “I’ll remember what it is” we all say years later. But sometimes we might upgrade an antenna or radio. In doing so, it is far easier to use the same cable if it is ok, especially if it goes down a wall or through a small hole. After a few changes, the whole thing can become a bit of a mess (not that anyone else needs to know).

Power cables are easier to manage, as I stick a sticker on each plug at the power board to remind me what they go to. So, if I need to change the power board, I know exactly which plug I am pulling out.

But antenna cables are a bit harder. I started writing on a post it notes what this cable was for and taped it to the cable near the plug, but if you swap it to something else, you must change the note. Maybe you forgot last time you changed something or ran out of time. Perhaps after the testing you got so excited about the positive test you never did update the note on your cable.

So, I now have a new system. I colour code each cable at each end with electrical tape as shown below in the photo.

Using the same colour code on each end, I can now be sure which cable goes to which end. One of my cables has two of the same colour, which is fine, whatever works for you.

If you do this just before the plug at each end, then you can see which antenna the cable goes into and which radio. You could also do it again at the bottom of the tower or window so you know halfway along the cable.

I then have a list of yellow 1 strip = HF 6m and Red = VHF/UHF etc. if I swap the antennas, I just must change the list. I can double check by going outside to see what the same colour code ends up. The electrical tape will stay the same and will last a lot longer than handwritten notes.

So, what do you do to keep your station in order? Do you just remember? Do you have a system? Why not share it in the comments below so we can all learn from you.

Power without Power

In 2019 my family and I went on a five week trip through outback Australia to some of the remotest parts. We had no access to power, reception, food or water for days. We took what we had.

Here is a cheap way to have power without having power, a rather inexpensive way to do it. I took this short video in outback Northern Territory in the top end of Australia.
