[Elecraft] Digital Modes and K3S

[KE1B]

I had this working, but now can’t figure out how I did it, cuz it’s not working again.

Running Windows 7, N1MM+, K3S connected via USB.

CW and SSB work fine, including macros.

On RTTY (MMTTY), if I hit any macro key, the radio keys up (PTT), but there is no diddling. At that time, I see the characters being sent in the Digital Window, and the XY scope is apparently showing my transmitted signal. I just get a pure carrier.

On PSK (MMVARI), if I hit a macro key, the radio keys up (PTT), and the characters show up in the Digital Window, but again there is apparently no audio getting from the computer to the radio.

In the Configurer, I have selected the K3S Codec as the output device for the radio.

I have tried lots of variations in ports and AFSK/FSK and such, to no avail. What should I be checking?
