Re: New to me FT-857D low TX power on USB/LSB CW works just fine... Bad mic? Something else?
Have you performed the ALC adjustment for SSB? That is very important as it is set for your microphone and your voice.

Looking at the diagrams I tried using pin 2 (circled in red) to activate the switch. I was under the impression it was grounded while the radio was transmitting. I checked with a DMM there is no

Like most amateur equipment, SSB in the FT-857D is Single Sideband Supressed Carrier, unlike CW, which is actually "just" the carrier. FCC rules define amateur power in PEP [Peak Envelope Power]. (PEP

Re: FT857 + FC-40 + CAT
