[Elecraft] K3 Sub Rx RF Gain issue and TX sticking

[K4ia via Elecraft]

The RF Gain control on the Sub RX acts weird.  It will seem deaf until 3 
o'clock on the dial.   Once past 3, the gain jumps up and then is linear 
if you turn it down.   This pattern will repeat if you turn off the Sub 
Rx and turn it back on again.  The main RX Rf Gain control is smooth and 
linear all through the dial range.   I have done the RX calibration 
routine on both receivers.

During Field Day, if I hit the Esc Key or the paddle to interrupt a CQ 
(N1MM+) , my external keyer (MKUSB) would stop keying but the rig would 
stay in transmit mode.  Tapping the XMT button would put the rig back to 
RX mode.

Ideas?
