They may not be using the DATA mode; many folks use USB for PSK31 -- but then compression can be an issue.

Come to think of it, it would be good to know just how they are set up -- which mode, which modem (e.g., SignaLink usb), etc.

Compression should not matter, because that is disabled in DATA A mode.

I'd save the config, EEINIT, and reload. If that doesn't fix it, ask

Julie,

Check to be certain Compression is set to zero.
If it was not set to zero, you should also re-adjust the audio level (either 
with the computer soundcard level settings or the KX3 Mic Gain).

Hello to all!  Our KX3 that Larry uses for PSK has mysteriously developed an 
unstable ALC bar setting.
If we use the mic gain to set it for 4 bars while transmitting, then on the 
next transmission, without our having touched any controls, it goes back up to 
6 or 7 bars.
Any ideas what could have changed to make this happen?
We must have inadvertently changed something but I don't know what.
THANKS!
