*Description:*
Receiver schematic for the home brew 15-Meter transceiver that I am building. It is complete, except for the Audio AGC section. The first version that I tried didn't work at all well, so back to the drawing board. I'll figure something out eventually. In the mean time, this much works just fine. Without the front-end filter section, I can copy signals on any of the ham bands, just by setting the VFO to the correct frequency. I've tried 80, 40 and 20 meters, and a quick foray to 15 MHz for WWVB. I'll update and release the PCB that I built it on when the Audio AGC issue is resolved. Jim, K8IQY, March13, 2023
