[Elecraft] K2 tx/rx switching problem - help please ;-)

[Don Wilhelm]

Vic,

Another thing to check is your coax - a loose coax or one that has a 
failed connection to the shield will behave as you have experienced.  It 
may transmit OK, but is slow returning a good path for receive.
Admittedly, it should fault regardless of CW or SSB, but is worth a look 
in any case.  The best check is to substitute another coax.
