There are lots of interesting hobbyist/hacker/maker projects as well, like the sdr chips, HF kits like uBitX, and FaradayRF. One of my coworkers has his license to track model rockets with a small transmitter that sends GPS telemetry. Lots of cool stuff!
I (Amateur Extra) ordered a BitX40 and about a month later they announced the uBitX... so I've ordered one of those, and not only going to hack the firmware and do some upgrades but also learn about 3D printing to make a case :)
