[Elecraft] K3 - ERR PTT

[Jim Miller KG0KP]

Anybody have any ideas? I took the bottom rear cover off and don't see 
anything. It looks like it will be a chore to get to it from the top.

Nothing plugged in except the power cable. ERR PTT  anytime it is turned on. 
One more thing, the last few days, the CW key would NOT work at all, paddle 
still OK. Tested on another radio and the key and cable are just fine.

Not that it has turned to a solid problem, I see that it was causing my 
previous intermittent problems as well.  When I turned it on, it would do 
repeated short transmit "pulses" all just a partial second each and random 
and not of any significant length to start.  I thought it was being caused 
my the P3 as it would generally stop when I turned it off. but all was OK 
after maybe 20 or 30 seconds as it slowed and then quit. I usually turned it 
to test tx as quickly as I could and started it with the dummy load selected 
anyway.

Nothing was changed that I can remember and nothing at all had been done 
recently, not even the recent updates for the past 2? months.  I downloaded 
the updates and installed them and then a couple of days later, it turned 
solid but I think the intermittent problems I had been having were actually 
the same problem and it probably was not being caused by the P3.
