[Elecraft] [KX3] CW +SSB with external transverter problem

[Jim Stahl via Elecraft]

You need to set the VOX Delay while in the CW mode, to a long enough time to keep the transverter from dropping out. You'll likely want to reset that if you go back to CW operation without the transverter.


Also, it was a relatively recent firmware version that fixed the problem. Be sure you have the latest version.

One further note, I am using an external keyer, not the KX3 internal keyer. I
just tried the internal keyer and it does work as I would expect.
