When the OII is in FSK mode, it expects fsk keying through the AUX port.
Without fsk keying, all you get out is a steady carrier. To use AFSK, the
OII has to be in SSB mode. I've used both - finally settled on true FSK
since too much audio and you splatter all over the place with AFSK.
Further, the passband is automatically shifted for receive when you put it
in FSK mode - you have to do that manually when you receive RTTY in SSB
mode.

Subject: [TenTec] O II w/HRD/DM780
Does the O II do AFSK? If so, how do I set it up....I am trying to use
HamRadioDeluxe along with DM780....my interface is the microKeyer
II...in FSK, I read just fine but when trying to xmit, I get steady
carrier and no tone changes. I can not confirm if DM780 does FSK or
not....any suggestions greatly appreciated.
