[Elecraft] RTTY on the K3S

[Salvatore Irato]

Hi rich and all.
Maybe you have selected the wrong audio output device. You need to
change it accordingly to the new K3S USB audio interface that appeared
when the USB was inserted ... and the driver was inserted.

Maybe you have the audio generator AFSK level (inside the program i.e.
MMTTY) or the USB audio level for the proper interface way down.

But, more ... that's the best candidate!
Maybe you have something other wron as you wrote that you are getting
a pure carrier. This would mean that you are still setup as FSK and
are getting the mark carrier without the diddling to shift carrier ...
this mean that yours radio still wait for FSK manipulation and not for
the AFSK tones in input.
Having the radio properly setup for AFSK audio tones input will give
you nothing when in TX without tones, no carrier I mean. No audio no
RF ouput.
The AFSK audio tones gives you the proper RF output as on SSB.
Contrarily when you have the FSK submode setup you get plenty of RF
but no diddles if there is not manipulation in between tones.

UR radio is FSK, UR computer is AFSK. Isn't?

I would double check the Radio SubMode and after the interface, levels
setups whatever they live.

 Have a check and let us know, pse.

PS use again the Joe's advice and list on the radio side. SubMode
seems to be the key in your case at least from here.
