Radio

Amateur Radio is probably my most important non sporting hobby. It has shaped my interests, my career, the things I do in the hackerspace and the way I spend almost all of my non-professional time. I currently operate as MM0RFN, ex 2M0HIB & MM3ZRZ.

These are the collected results and thoughts from my years of experimentation and play in this area.

EuroBSDCon 2024 Report

This year I attended EuroBSDCon 2024 in Dublin. I always appreciate an excuse to head over to Ireland, and this seemed like a great chance to spend some time in Dublin and learn new things. Due to constraints on my time I didn’t go to the 2 day devsummit that precedes the conference, only the main event itself. The Event EuroBSDCon was attended by about 200-250 people, the hardcore of the BSD community! Attendees came from all over, I met Canadians, USAians, Germanians, Belgians and Irelandians amongst other nationalities! …

What I've been up to in Open Ham Radio - July 2024

I do a lot in free software for ham radio, and Steve at Zero Retries encouraged me to take this email I sent him and translate it into something here. UK Packet Radio Network UKPRN is going nicely, with the Nottingham and South segment really quite impressively interconnected over RF - https://nodes.ukpacketradio.network/packet-network-map.html?rfonly=1 I’m excited to see the growth down there! We’re sorting out forwarding and routes in Aberdeen too, and working to grow the RF path to Inverness. …

SOTA Trip Reports: April 24th 2021 - Moray Coast

tj and I figured that to fit the 3 Moray coast hills we were interested in climbing, now that the restrictions are eased, an early start would be required! The longest walk should go first and the activation times on each hill would be limited. Predictably, we left at 1030, got a bit lost and I got too excited on the radio, so none of the self made rules were followed! …

Radio Power in the Field - Follow on

Previously, I wrote about building a battery for my portable radio operations. This project has been a long and agonising one. Batteries are really difficult, and I spent a good chunk of June, July and August thinking about them. The Winning Design As I discussed in that last blog post, the architecture I settled upon was: I’ve learned quite a lot, made a large number of wrong assumptions and joined a lot of dots in my head as this has gone on. I’ve also made a large number of observations that will be helpful to other people interested in battery powered radio operation. …
