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.

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
