[Elecraft] KX3 No meter indication when transmitting digital

[Tony Estep]

Well, I've tracked it down. I don't have a fix yet but at least I have
found out something

For whatever reason, the WSJT software stops putting out audio
unexpectedly. It works for a while, then it doesn't. I don't think it's RF
getting back into the computer, because it happens even when transmitting
to a dummy load at a very low power level of 0.1 watt. Perhaps it's some
problem between the software and my audio driver.  I'm pretty sure I'll get
it fixed.

Thanks again to everyone who responded.
