I use sbuild and btrfs for my debian packaging, it’s quick, solid and was a big improvement on my git-pbuilder setup. I think that’s due to the snapshotting and disposable nature of live chroots. This has been my bible for this, and is a regular reference for me when things break. At the moment, I’m working on a project which will require a repository covering multiple architectures, distribuitions and targets. I’m looking at ubuntu i386, x84_64, maybe armhf/aarch64, raspberry pi armhf & aarch64 and some debian targets too eventually. …

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! …

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. …

Here’re my first sota trip reports. I made some mistakes and have lots to learn still, but they were great days out and I’m dead keen to do more. Most importantly, I’ve got better at radio in general - I’m much more comfortable on a microphone, I understand the flow and format of an HF contact far better. It’s very different from the datamodes I’ve been doing for years! One thing that I’ve noticed, and it probably deserves mentioning, is that the SOTA web infrastructure is some of the best I’ve seen in ham radio. Modern looking sites, coherent single sign on and services sharing data in a really clever way. I upload CSV format logs generated by my logging program, cqrlog, and the SOTA infrastructure handles them and shares them with services like sotamapping, to show me maps of my contacts. SOTA spots appear on APRS, and I can spot myself to sotwatch using APRS messages. I’m super impressed! …

I’ve been talking to Iain, MM0ROR a bit on the radio. After I persuaded him to build a 70cm version of the 1/4 wave vertical antenna I built earlier this year, I helped him test it on the radio tonight from my new /m setup. Initially I drove to the picturesque Aberdeen Beach, then the less pretty 57North Hacklab, and finally I took the long road to the very lovely Balmedie Beach, and for the bulk of the drive nattered away to Iain about nonsense and radios. …
