Oh my, what have I done
Don't take away my QRP CW card.
I picked up an old, high impedance Heathkit microphone having the appropriate 2-pin connector. One pin is the mic line and the other is for the PTT switch. The shield is common.
I set the mic level to indicate some movement on the ALC and peaks were occurring around 100w. QRP SSB will be tough to achieve.
I worked a few stations on 80m and they delivered great reports and offered their own stories of Heathkit radios.
The old rig is certainly a conversation starter.
That's all for now
So... well, my QRP saying doesn't go with this post, so... warm your tubes and smell the cooking resistors
