NOTE – 17th May 2025This has been re-written for Raspberry Pi Bookworm and has been tested on a Raspberry Pi4 using the 64 bit version of the operating system. Over the last four or five years I’ve been a regular user of two digital voice modes, D-STAR and DMR. I don’t particularly like to use […]
Earlier this year I replaced my Hexbeam (with another Hexbeam) and I wrote about it on this site. There was a gap of a couple of weeks when I was between aerials and to take advantage of that, I temporarily moved my ADS-B receiver to a temporary stub mast, effectively raising it 7ft from the […]
It’s been well over a year since I moved my external ADS-B receiver to the top of my Alimast and it’s been performing very well, regularly sitting in the top five of the UK receivers according to the FlightAware statistics page and in the top ten world wide on the PlaneFinder sharers list. A good location […]
A few years ago I set up a DXCluster using AR-Cluster on my old Mac Mini with Windows XP installed. It ran for a long time, I had good connections into the network and although it was listed on the DX Cluster info page, nobody ever connected to me. This was fine, the cluster was […]
** image has been updated as of 21/04/2018 to resolve the problems some people had booting their Pi ** Note: 27/02/2022 The compressed version is available via SourceForge, is not corrupted and will still work if you can decompress it. I am still seeding the two torrent files, the compressed one is here and the […]
If you use any of the data modes for QSOs such as JT65, JT9, or FT8 or if you operate using WSPR then you’ll know how important it is that your computer clock is accurate. Anything more than a couple of seconds out and you won’t decode anything and nobody will decode your signal. On […]
Not long after my last post on this subject, back in January, the preamp I had mounted in the box at the top of 30ft of pole strapped to the side of my house failed and I was forced to removed that particular ADS-B aircraft tracker. I still had my loft unit running and working […]
After my posts about building an APRS RX iGate, I entered into email discussion with Alan, K2RHK who pointed me towards his website specifically to see his experiments in APRS. While looking through his site, I noticed he’d recommended a book for those looking to learn how to program a Raspberry Pi. I mentioned that this was […]
I wasn’t sure whether to post this or not as it’s not specifically amateur radio – But there’s a small amount of electronics involved so I figured it might be of interest. A few days ago while Susan and I were out, I received a text from my son saying “I thought you’d like to […]
A little history In January 2000 I started running the first licensed APRS Internet gateway in the UK originally with the callsign GB7UIV. Within a week of experiments starting on the 26th January 2000, the gateway was on air and connected to the internet 24/7 except for periods when the connection dropped out and the […]
