[Elecraft] K3 Goes to TX on Turn ON

[Don Wilhelm]

Paul,

Have you disconnected the RS-232 cable to the PC from the P3?  If not, 
try that and then connect the RS-232 cable between the P3 and K3.  If 
the problem is resolved with only that cable in place, blame your 
computer, but if the problem happens with no computer connection to the 
P3, contact P3support.

After connecting and disconnecting all external connections to K3, I determined the culprit was the RS-232 cable to the P3. If I disconnect the cable problem goes away, red TX light goes out. I tried swapping  RS-232 cables but same problem exists. Any ideas where to look on this ?? The P3 and K3 have been co-existing fine til last night.
