Homebrew 40m SSB rig gets CW, keyer, break-in, AGC and metering

A couple of ‘solder sessions’ finished all the wiring, debugging and testing required to deploy my Arduino Nano keyer and SWR/power meter, and the LED LDR AGC and S-meter modules into my homebrew 40 meter SSB rig (MST Mk1 from OzQrp).  Before reassembly I sprayed the front and rear panels, and added my preferred DecaDry white lettering and a protective coat of  clear satin sealer. It’s now resplendent with all the expected features of a SSB/CW monoband portable rig.

The Nano keyer and RF sampler sits over the SO239 socket on the rear panel, and the AGC and S-meter board juts out from under edge mounting analogue meter (above). Various switchery and socketry fill up the rear panel (below).

Close-up of the AGC/S-meter board in situ (above). The rig now emits white and blue light from 4 sources–a blue chip LED on the Nano, the white-on-blue display, the white AGC LED and a high intensity white LED illuminating the meter scale from the side (below).

Summit CW test to follow.
