Intro

A few months back I was working on the KeithSDR transceiver. I got to that project a little bit late and there was not much activity going on at that time. In addition, the transceiver does not include its own RF stage and instead relies on a HobbyPCB SDR, which is no longer available.

As a result, I ended up building my unit as a receiver-only device, limited to the 20-meter band, using a QRP Labs receiver module. Although any IQ RF receiver could potentially work with this project, the T41-EP began to draw my attention, and I eventually considered my KeithSDR project complete.
