I built a 36 MHz transverter with a 6146 final, mixed it with the 14 MHz
output of the SB-10, and had a great 6 meter sideband transmitter. The
Apache provided the SB-10 drive and power requirements. Still have that
transverter around here somewhere. Receiving side consisted of an Ameco
CN-50 into a HQ-170A-VHF
