Cannot transmit PSK31 with WinWarbler. Receive works fine. RTTY TX/RX works fine.

Cannot transmit PSK31 using WinWarbler or MuliPSK on 6700. RTTY sending and receiving works fine. On PSK, I see good level on DAX control Panel TX Stream meter; however, no indication on Radio Panel Level meter. USing Digu as mode. If I change mode to USB, I see good level on Radio level meter and hear good sounds when MON is enabled; however, no power output. Using SmartSDR 1.9.7. Any ideas?

    Is the RF power slider set to zero when you go to DIGU? It seems the DAX input is still enabled if you are getting an audio level showing. Does the audio level go up to the red without being red? Is TX selected for the slice you are using?

    If you see a good audio level then I wouldn't suspect a WinWarbler setting (you use that for both PSK and RTTY (AFSK)?). Maybe check the configuration for PTT though. I have mine set for Mode Xcvr Ctrl App and Port none.

    That's all I can think of. Good luck!

    Also check your transmit passband - AFSK tones above the cutoff won't be transmitted.
