My BITX40 sounds good in receive - especially after I installed all new crystals from Digi-Key (tall version).
Anyway transmit is still distorted and hard to make out. On my K3's Panadapter it looks like double sideband.
This got me to think how does the Raduino know it's in transmit?? I think I am missing a wire to two to it? The online
wiring diagram just shows the tuning pot, VFO out, and power.? What about the transmit - shouldn't the VFO or DDS
signal be shifted when in transmit???
What about the PTT sense to A0 shown in the attached diagram?
Thank you,
