Solar Data & Propagation

There are several website that tell you what bands are open in your area. Most people paste them on their QRZ page, but there are some examples below that update every hour.

You can see more on their webpage https://www.hamqsl.com/solar.html where all you have to do is paste the code and put on your website. There is a great option to donate also. There is a wealth of information on this website that you can spend hours on.

This data is updated every hour, which is fantastic.

But what if you are not in front of your PC and want to look it up. There is a handy little app I use called Solar Data and Propagation. It is a small app only 12.5Mb in size on the iPhone and it is free. It is also available on Android at only 6.75Mb, I will talk about further down.

Below is the app on an apple device.

While it is only a little app, and doesn’t do a lot, it is a simple app that gives you what propagation is open at your current location. While other apps have heaps of features and functions that you may or may not use often, this little app has just what you would use often.

Above are the HF conditions, but you can also see VHF conditions and terrestrial. Adds do pop up from time to time, but the app is free so I don’t see this as a problem.

You can download it from the App Store.

Android

If you have an Android device, go to the store and search for HF Propagation. It should be the first one on the list with an orange sunshine as the logo.

Once installed, you have a lot of different options available on the first screen.

Scroll down, and you will see the HF then VHF conditions as mentioned for the Apple app.

Conclusion

This little information may save you from running out to the shack and turning everything on to find nothing or trying on the wrong band. As mentioned above, it can be on an apple or android device.

Hopefully, this makes it a little easier for you. Please put in the comments below what apps you enjoy using or let me know what you think.

Happy DX-ing, hopefully we talk on the air soon.

HamAlert

It has been a while since I have completed another update, but I have a lot in the making. A broken finger has kept me quiet!

HamAlert is an app for both iPhone and Google devices that alerts you as to when a desired station appears on the DX cluster, the Beacon Network, SOTAwatch, POTA or PSK Reporter. It saves you from checking them all manually.

You can receive different types of alerts including:

  • DXCC (both actual and callsign home DXCC)
  • Callsign
  • IOTA group reference
  • SOTA summit reference
  • WWFF/POTA division/reference
  • CQ zone
  • Continent
  • Band
  • Mode
  • Time and days of week
  • Source
  • Spotter callsign and DXCC

Just download the app from the App Store or google play, create an account, then set what alerts or triggers you want.

Press the three lines up the top left and select triggers. Then press plus to add one. The interface is mostly web based but works well within the app.

My first trigger was using my call sign under any conditions and alert via app

You can easily add more triggers. Select a condition and an Action on what you want the app to do when it meats the desired condition. You can also add in a comment to help you with each trigger.

Once you are done, simply press Done down the bottom of the screen.

Limitations

Limitations menu limits how many times you will be triggered. For example you may want to set a trigger to only alert you once an hour or day.

More information is available on their website at https://hamalert.org/about which even had a forum you can join or add comments about the app.

How do you find this app? Would value your comments below.

M17

So what is the new digital mode M17? It sounds like a gun at first, however I am sure you if you google M17 Ham Project you will not be a red flag to the police.

At the time of writing this, M17 is said to be a new digital radio protocol which is still in development, however currently available. It was first started in 2019. The M17 Working Group is a team of several people from around the world, but headed up by Wojciech (SP5WWP) in Poland.

As per their website, they have said that teh desire of the M17 project is to provide:

  • an Open-Source community
  • freely available and modifiable digital radio protocol
  • open hardware designs

M17 uses Frequency Division Multiple Access (FDMA) instead of Time Division Multiple Access (TDMA). FDMA in our case, allows for two 6.25kHz simultaneous links to be established on one 12.5kHz channel. It supports APRS however is not compatible with DMR. DMR is built for profesional use, and can be used for Ham operators, but can be clunky especially when it comes to writing code plugs.

There is more information available at this M17 website.

A lot of people have been talking about this project and you can see the current reflector list on this site. Maybe it is something you should try?

More information will be available as this project continues. I would value your comments on this project, does this sort of thing excite you or raise more questions than answers?

GD-77 Won’t connect to PC

I have been using my Radioddity now for some years and love it.  Though upgrading this to the OpenGD77 opened a whole new world and it gets better all the time.

One issue I had for a period was not being able to connect to it via my PC. For some time, it worked, then it stopped. It was most frustrating as I could not run the radio as a local repeater anymore. I almost never update the codeplug now and update the firmware every few weeks, but I could not do any of this without my PC connection.

After checking I had the latest community programming software, I was stumped.

Roger, who is behind all the programming of this radio and who lives nearby, kindly gave me some advice over email.  He suggested it was a Com-Port issue.  And he was correct.  So, I have put this together to help others who may have the same problem as I did.

From windows 10, type in the search box Device Manager.  Then you will get a box like the following.

If you expand out the Ports section, you can see the issue I had straight away, I had the OpenGD77 on com port 4, and an Eltima Virtual Serial Port on com port 2-4 also.

I disabled the Eltima com ports listed by right clicking on them and nothing seemed to stop working, so then I uninstalled them both.  And straight away the com port worked through to the radio like it used to.

Great to have my GD77 back in action!  Hopefully this has helped you, if it has, please let me know.

DudeStar

Here is a free windows program that will connect your PC to:

  • DMR
  • Yaesu Fusion
  • DStar
  • M17
  • P25
  • NXDN

You can do all this without needing to purchase a radio. I prefer to use a radio, however I thought I would put this review together to help others who may not or want to try before they buy. Obviously you need to be licenced first.

The software was started by Doug, AD8DP (he’s contact details are on QRZ), and seems to work well. While the audio is better via a radio, this is an option you can use if even to only listen.

First step is to go to the Dudestar GitHub page at the following address: https://github.com/nostar/dudestar. You can see down the bottom of this page how to install for Lynx. Or try this site (it keeps changing): http://radio.xreflector.es/index.php/575-2/?fbclid=IwAR2GPPD3OXkjLWXj-r9e1QZtN2bzM6kIPoXodyEJ2URKlGRzJ0Q1-vC6VSg

The next step is to run the executable file from the download releases link page here. https://github.com/nostar/dudestar/releases Just click on the Assets arrow, and press on the appropriate exe file. It is only about 20mb big, so wont take long to download.

Once downloaded, run the file. If you get a windows protection message, click on more info then run anyway. Alternatively right click on the file, go to properties and unblock. Everything runs from the downloaded file – nothing is installed.

Some of the settings to set

Settings Tab – vcoder should be set to software vecoder. You can set your playback and capture device if you don’t want it to be the default. Put in your call sign. Down the bottom of this tab is where you can update ID Files and Update host files – it doesn’t look like it did anything, but if you look on the log tab, you will see it does.

Main Tab – You can adjust the volume and mic gain on this page. It has been recommended to set the mic gain to 10% – 30% to start with. This will change depending on the microphone you use and even the mode you are on.

You can see the available modes via the list above

Getting connected

Lets get connected on Fusion as that is the easiest to start with. From the Main tab, in the mode area, select YSF. Then you can select a host or talk group you want to talk to.

Then press connect to connect. To transmit, press the TX button or space bar.

As someone keys up, you should see their call sign populated in the main tab.

Changing Modes

First disconnect via the main tab. If you want to try DMR, you will need to put in your DMR ID and password. Then via the main tab, select DMR, and select a master server. If you select a BM one then you will be on the BrandMeister network. Then type in the talk group and tick SWRX (software RX), and SWTX (software TX).

I think the software is a great start and with everything will be worked on and updated. I notice if you listen via your PC and radio at the same time, it will come through the PC first as the radio and hotspot is perhaps slower in decoding.

If you have any comments, please put them below. This page is only valid for the current version, and I am sure there will be changes.

Hints

One thing you can do it run the program more than once and monitor two different networks or talk groups. A great feature but unless you are looking at the screen, it can be hard to know which one spoke. So I either make the volumes different, or patch the sound through to the speakers in my monitors (as I have more than one).

There is a good discussion group here if you want to join the discussion. It is also about DudeStar which was written by the same person.

Welle.io

Welle.io is a DAB and DAB+ software defined radio (SDR). It runs on Windows, Linux and embedded devices like the Raspberry Pi 2 and 3.

You can find the program and where to download it from their website.

Using the Software

With all these things, the software is updated regularly. You can see on the page where you download it from, what changes have been made with each version. The first thing I struggled to find was how to tune in the stations. I will show you how to further on in this post.

This is how the program looked while writing this review

Settings

If you select the three dots up the far top right, you can select settings. I recommend keeping them as is unless you want to change something here. The Auto Detect should select your SDR that is connected.

If your keen, you can also check out the Expert Settings from the same area.

Tuning in Stations

Towards the top left of the interface is a All Stations button. To the right of this is three little buttons. Click on this and select Start Station Scan. This will give you a list of stations once it is finished. You can star the ones you like to create a favorited list.

Changing Display

You can add displays by pressing the orange plus button down the bottom right. Some of the displays change as you hover over them, others have waterfalls. They can be removed or added as needed. I assume these will change all the time as the program is developed.

Recording

The app allows you to record the station you are listening to. By default, recordings are MP2 files stored in the /tmp folder.

Hotkeys

There are several hotkeys that can be turned on or off. They included m = mute audio, r = start or stop recording, – = switch to previous service, + = switch to the next service and so on.

Slideshow

Some stations transmit a slideshow. I have usually found this is just the station’s logo or the current program’s logo. The program is able to display this after it receives it without errors.

Summary

In summary, I highly recommend this easy to use software with your SDR device. It is extremely easy to set up and get going. At the time of writing this, there are only a couple of YouTube video’s and hardly any reviews. The YouTube video’s appear to be from the developer and just show you how to set it up. I believe this simple program will become popular in time mainly because of how easy it is to setup.

I hope you enjoy the read, please let me know below what you thought or have any comments.

Hotspot Fixing Packet Loss with AutoCal

The thing with digital communications, it can be extremely complicated. It only takes one tick box to be ticked incorrectly to take your station off the air.  Just as easily one tick box will get you on the air and sounding great.

With Analogue, it was all about antenna gain, SWA, power and height.  Digital is vastly different, especially via a hotspot, as it is all about lack of power, mic gain and packet loss.  Packet loss can be tricky and is often put down to a bad internet connection.  However, that is not always the reason, and if your internet is good, and your packet loss is above 1%, then it can get tricky to know why.

Assuming you have a good connection, you have your hotspot close to your modem if it is via wifi and your radio is also close to your hotspot, then here is something you may want to try.  I will explain how to do it using an OpenSpot, as that is what I am using, however, most hotspots may have the same or similar features.

After many years of using the same hotspot, I noticed more and more the hotspot didn’t seem to recognise my signal from my radio.  I could hear fine, and my hotspot even said it was receiving my signal, but my call didn’t come up on the dashboard and the other person couldn’t receive my signal unless it did come up on the dashboard.

It started 3 in 1 times I would trigger the hotspot like normal, then it changed to 1 in 3.  It got worse before it made the hotspot almost unusable.

My hotspot, an OpenSpot2, has a AutoCal option and will analyse an incoming signal and tries to find out the frequency difference between the OpenSpot and the transmitter. They suggest that you only run AutoCal feature if the openSPOT2 shows BER above 1% for your radio’s transmission, as errors in the voice stream usually won’t be noticeable if the BER is below 1%.

You can see this on the OpenSpot by going to the Status screen and open the BER graph and transmit. A quicker way is to look when you transmit on the dashboard of your OpenSpot, you can see below the BER is next to the B, and this example has a loss of 1.3%.

Dashboard showing BER loss.

With the Openspot, press the quick setup button, select the type of radio you are using (I am using a DMR radio), and then you can see the AutoCal button.

All you need to do is press that AutoCal button.  Then scroll down and you will see it doing the three phases. Make sure the correct modem mode is selected. Hold the PTT button on your radio until all 3 phases are completed. Once complete, you can try the echo test to check you are working well.

Then you can return to normal use and the BER should have reduced to well below 1%.

OpenSpot have more information here in their user manual.

I hope this helped you, and if you enjoyed it, here are some other posts I have done. Please don’t forget to put your email address in to make sure you get the latest posts.

OpenSpot from the Start

I have spoken to a few people who have felt a bit overwhelmed setting up their OpenSpot from the start. In saying that, I have always been surprised how many people are on digital, some of them have no computer experience at all.  It only takes one tickbox to be selected wrongly and you are off the air totally.  So clearly there are a lot of helpful Amateurs out there.  This website is my way of helping, as I can’t be all over the world to help.  I have put things of interest as I find them on my site.  If you find it interesting, please subscribe or let me know.

In saying that, OpenSpot has been setup to be as easy as possible with a lot of thought behind it.  While I am not claiming this is the best hotspot, I am saying I have two of them and found them great to use at home, mobile, and portable.

This is what I do with my openspot2.

Starting from the beginning

Plug your OpenSpot2 in

Turn your mobile phone wifi (or could use a tablet or laptop with wifi) on and connect to your openSPOT2 AP

If the popup page does not show up (it may take a while to load), type in openspot2.local in a web browser

A welcome screen will ask you to select your country

Scan or manually select your home wifi

Press connect and type in your password for your home wifi

After pressing ok, you will get a message saying this hotspot is going to connect to the wifi now instead of directly connecting to your phone

You can then connect to it via your phone or device that is connected to the home wifi.  I recommend you do this via a pc as you get more functions on screen, however you can do it via a mobile phone with a smaller screen. To connect, go to openspot2.local in a web browser.  However, if you have two openspot2’s on your network, as I do, you will need to log into your network modem and check the actual ip address of your openspot.

If you can not find it on your network, then I suggest you go back to your phone and see if you can connect to your openspot again via wifi.  If it is not there, you may need to unplug the power cord and plug it back in a minute or so later, or press the button next to the power cord until the light goes white to reset it and start again.

Once you connect via the wifi network to your Openspot for the first time you will get a Quick Setup Screen.

Put in your call sign and the DMR ID will auto populate.  You can put in your NXDN ID also.

Select the type of radio you will be using to connect to the OpenSpot.

Type in the frequency you want to use while using the Openspot.  Make sure it is a different frequency to all other hotspots so you don’t get hotspot feedback. Keep colour code as 1. Then select the network you want to connect to.

Treehouse

An unusual name, but a catchy name no less, just like Peanut that was written by the same person, David PA7LIM. If you like Peanut, then you will like this project also. This project, like Peanut, includes some amazing coding and thinking.

Launched in 2020, the main website for Treehouse is found off David’s web site. This project is a YSF reflector with multiple rooms.

Dashboard

You can see the dashboard via this link http://europelink.pa7lim.nl/ it is a very similar layout to the Peanut one.

If you open the above dashboard, you will see down the left side in the Room Control section, a message stating your hotspot is not logged in to this reflector.

There are several ways you can connect, but here are a few in no particular order.

BlueDV

A friend of mine, Chris, put this video together. He uses BlueDV to get onto it.

YSF – via your hotspot

As I use an Openspot2, my instructions will show you how I do it, however I am sure you can apply similar to your hotspot should you have a different one.

First you need to connect to the YSF reflector called EUROPELINK, and according to the YSD reflector register, this has an ID number of 00007. If you don’t know how I found this, go to the YSF Reflector Registry page and type in EUROPELINK in the search box, and you can see the ID number of 0007.

Back to the Openspot2, I select Quick Setup, then I select DMR, as I am using a DMR radio, then select YSFReflector then in the Server box, I type in 00007 or EUROPELINK, to select that reflector. Doing this will connect my DMR radio to the YSF system.

Almost instantly, the Room Control section of the dashboard has updated to my call sign and I now have a drop-down list where I can select which room I want to connect to. You can then select the room you want.

As you transmit, you will see your call in the Active QSO’s screen.

While this is not connected to the Peanut Dashboard, there will be rooms that go across to each other. The Online Stations section of the Dashboard has the time stations connected.

There is a new AU-NZ room which is good and was quickly made after it was requested to David. Some rooms link just to themselves, like the English room and so on, while others connect beyond the internet. Remember this reflector will get busier as time goes on.

Also, this setup is still very new, and like Peanut, it took a little while to become popular.  Having said that, Peanut took off quickly and given the success of that, and a lot of people at home during the 2020 Pandemic, I believe this will take off quickly also.
