MD-1C8 desktop mic on FT-900 using CT-20

Postby KF7ZTM » Thu Sep 22, 2016 4:19 pm

I inherited an FT-900 with a MH-31A8J hand mic and a MD-1C8 desktop mic which were all used. The hand mic works fine, but the desktop mic seems to have some problems. The FT-900 manual talks about using the desktop mic with a CT-20 cable to adapt it. I am guessing the cable is the issue, in the matter of fact, things like the PTT signal is not carried through. I have checked multiple times on the Internet & talking to Yaesu USA for information on this cable . . . manual, wiring diagram, anything . . . to no avail. Does anyone have this information? Yaesu wondered if this cable was ever made, but I have seen some people that sold this model of cable as recent as a year ago. Any help is appreciated. 73
