[Elecraft] Hang-up on Relay Using QSK

[KY7M]

Towards the end of CQWW CW, I was having issues with the K3 not getting back
to receive when I stopped transmitting.  This was an intermittent problem -
if I keyed the radio again with a dit or two, I could get back to full
receive.  I could still hear signals, but greatly attenuated when the relay
would hang up.  I was using QSK with the K3 and my Alpha 87A.  I am not
seeing any fault indication on the 87A and I am trying to figure out if the
problem is in the K3.  I also have a KPA500 but have not used it in a
contest lately to know if the problem would repeat with another amplifier or
barefoot.  It seems to happen only after heavy use.  I think I experienced
it a week earlier in the WAE RTTY contest as well, but did not do as much
operating as in CQWW.
