[Elecraft] K3: activating sub receiver disables tx ?

[ww2r2 at g4fre.com]

I wonder if anyone else has experienced the following? (and what the cure 
was?) 

In a k3 with atu xverter interface and subrx. 

Ant 1 is selected 

vfo a is set to cw mode and receives OK. Keying it shows rf output on the k3 
power meter and the external power meter 

vfo b is set to cw mode on the same band. Doing an a/b swap and it receives 
OK, Keying it shows rf output on the k3 power meter and the external power 
meter 

if I activate split (rx a tx b) using the above settings, keying shows rf 
output on the k3 power meter and the external power meter 

however if I activate the subreceiver with split (still) enabled keying 
shows NO rf output on the k3 power meter and NO rf on the external power 
meter. A signal can be heard on a monitor receiver. 


Also if I leave the subreceiver activated and turn off the split (no split) 
keying still shows NO rf output on the k3 power meter and NO rf on the 
external power meter. A signal can be heard on a monitor receiver 

using <bset> <ant> changes the subrx receive path as expected but doesnt 
affect the tx output 

I was using the 2.82 software. I rolled back to 2.76 but still have the same 
issue
