The Evolve series of headset is being (at least that is my understanding) phased out and replaced by the Evolve2 series. As a matter of fact it is easy to get some good bargains on …
A couple of month ago I Bluetooth enabled my second Tinytrak 4 using a HC-06 module. It turned out this failed after a few weeks and the HC-06 is not usable for APRS.
After almost 8 weeks of using this little radio for my mobile APRS operations I thought it’s a good time to provide some feedback. I must admit I have mixed feelings about this radio…

I keep on reading about “Digital APRS” vs “Analog APRS”. Youtube and social media are full of these words. This is utterly wrong. Whenever I hear “Analog APRS” I’m going mental: “Analog APRS” simply does …
I got myself a second TinyTrak 4 and wanted to Bluetooth enable it like I did for my first one. I went a different route using a different module and wiring it another way.
Ever got frustrated of not being able to contact a passing by station you just saw on APRS? APRS can also work as a nearby station radar and help you out with that.
My TYT THD9000 started to exhibit some strange behavior, after transmitting it sometimes needs half a second to switch back to receive. So I was in the market for a new APRS radio and came …
On November 6th 2019 and December 5th 2019 Icom released new firmware. According to Icom’s claim on their latest release it fixes issues with “other manufacturers” hardware and that there were no issues with Icom …
Do you want your repeater or hotspot to automatically connect to a specified reflector at a certain time? It is quite easy to do that, almost no command line stuff is involved.
Setting up D-PRS on the Icom ID-5100 can be confusing for beginners as the radio has lots of options for D-PRS. Here are some step by step pictures an explanation I originally made for a …
As i mentionned in this earlier post, with the XLX reflectors came some confusion for the users. A few months (almost 18 months ago actually) I modded ircDDBGateway so that it’ll be able to connect …
In this article we’ll see how to run AX25 as a Systemd service, bringing the AX25 interface up on every boot and also putting the TNC into kiss mode. Having an AX25 interface allows you …
Byonics provides a Bluetooth add-on for the Tinytrak 4. While I love the TT4 I am not a huge fan of their TT4BT Bluetooth solution. It consists of a board with 2 DB9, no case …
Every now and then I keep on reading on social networks or forums how people set RX only igates up. RX only igates are just bad, really bad. I could just leave you with the …
Following my previous article about the REF/XRF/DCS/XLX differences I will try to explain what are ircddb and QuadNet and what they are good for. There is some misunderstanding about what those things are.
While listening to a QSO on a DStar repeater have you ever wondered how to know if the station you are listening to is local on the repeater or coming from a distant source (reflector, …
There is a widespread belief that aprs.fi is the internet backbone of the APRS network. It is not uncommon to read posts on social networks saying “I am connecting to aprs.fi with aprsdroid” or “I …
After publishing my article about updating ircDDBGateway in Pi-Star I received messages about how to update DStarRepeater as Pi-Star also ships with a quite outdated DStarRepeater. Updating it will get you the ability to use …
This is a question often raised by beginners to DStar : what is the difference between all those reflector types? I’ll try to give you an insight on this throughout this article.
Pi-Star allows everyone to setup and run a digital voice Hotspot easily, its ease of use largely contributed to the late Hotspot invasion. However, the DStar software shipping with it is quite outdated. It is …
No, I am not writing a blog exclusively about the TYT TH9000D. However I actually managed to run into the dreaded gibberish characters issue for a second time and to recover the radio!
After a couple of frustrations (here and here) I have finally managed to get my TYT TH-9000D running quite well with my Tinytrak 4. After a few weeks using it I must say I am …

So I had my Arduino Due based MMDVM up and running on the hill top and wanted to upload new firmware to it without driving 30km up to the repeater site. The Raspberry Pi3 it …
Introduction I came across a Motorola R100 repeater, those were very capable low to mid duty analogue repeaters in the mid 80s up to the 21st century, yet some of them are still in commercial …
