[Elecraft] K2 problem with SSB transmit

[Gary Krause]

I've noticed lately that my K2 will stop transmitting on SSB after a 
short period of time.  It has happened before.  If I turn it off and let 
it sit a while, it will work fine again.  It seems to me that perhaps it 
is some kind of thermal problem.  I haven't had a chance to look at it 
yet but, if anyone else has had this problem and knows what to look for, 
I would appreciate it.  My K2 is the 10 watt version.  CW works great 
with no problems.
Thanks,
