Man surprised you don’t recognize some of the components of the AN/GRC-106 been repairing and running these things for years now. I run high power RTTY, voice and attempt to do CW but my CW skills suck. Lot of us are running Vietnam/Cold War equipment being you get way more options then are available with the old WW2 stuff. Here is some video of my GRC-106 onboard my mutt back during AA83 event in October.
