[Elecraft] Problems with my K2 --- can anyone help??

[AJSOENKE at aol.com]

I had similar problem during the build of my 2nd K2.  I had the  experience 
during the First test stage - very few parts on RF Board.   Consequently I 
re-soldered many pads on the FP and Cont boards, to no  avail.
I discovered that I could press DISPLAY button and Menu button and get  
mainly correct responses, but no tuning. All voltage and resistance tests were  OK.
 
I resorted to doing a RESET on the EEPROM  (press 4+5+6 simultaneously  while 
turning ON power).
 
After that, all has been well since.
 
If you do a reset you will loose some EEPROM F/W setting you have made -  
filter configs, etc.
 
Check the supply voltage first, just in case it is falling too low. 
 
If the problem persists after reset and/or if it works but becomes  
intermittent, you should re seat the FP and Control boards in their connectors  and 
consider inspecting/re soldering control board pads.

My K2 just started with these issues  yesterday.

Does anyone have any suggestion other than sending the
rig  to Elecraft?

When I power the K2 up, it is like it has no  antenna
connection (I have the KAT 100 external tuner that I
use with the  rig). When I also power up only a few of
the letters for ELECRAFT appear on  the LED Screen.
Maybe 3 or 4 letters only and the S meter has three
bars  then a few blank and then 2 filled in. The rig
sounds like it is almost muted  or at times no audio.

Also when I power up, the KAT 100 shows the rig in  the
low power position even though I have the pot set for
100  watts.

It can take me about 5 to 10 minutes of turning the
rig on and  off until it will then function normally.
Once normal it is fine unless the  rig is off for about
an hour.

If I turn the rig off for an hour and  come back to it
it will not start normally and I have the same issues
all  over again.

I have checked all of my connections into the  rig
especially the power connections and antenna
connections.

It  kind of reminds me if I had an IC that was somehow
failing  somewhere?

Thanks for the feedback!
