Hi, Lou
Have an Orion II that I use with FSK, and on it you do have to key
the PTT which gives you carrier, and then the FSK provides the FSK keying.

Subject: [TenTec] Omni VI with MMTTY....
I am trying to hook up my omni VI to use MMTTY.
Made up an interface like this:
DB9 | Omni VI
---------------------------------------------------------------------------
Pin 3 ---- >|Diode --- ---3.3K resistor ----- Mark/Space center pin
|
|
1.8K
|
Pin 5 --------------------------------------|--- Mark/Space Shield
I measured the output on the Mark/Space center pin when I try and TX on
MMTTY... I get A Square wave output from 0- ~5.5v at the RCA connector, but
the OMNI VI does not transmit anything...
Am I missing something?? And yes the radio is in FSK mode...
Do I need a PTT line?
Thanks,
Lou
