I've been busy working on hardware and working at work, but I started to do some software at home that I kind of want to talk about. At least I want to write what I've discovered down where I can find it and who knows, maybe this will get picked up by a search engine and it might help someone else. In my last blog post, I talked about buying a HackRF One a few months ago, and I've been building a power amplifier for that. The first version of that power amplifier let the magic smoke out as soon as I powered it up, even before applying a signal to it.
