Problems with my K2 --- can anyone help??

Norm Klieman
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!

In trying to improve the subject, I've assumed that you have no received
signal, but I'm not completely sure what you mean by like not having an
antenna connection.

Exactly what appears on the L*C*D screen is important, as one of the
uses of the ELECRAFT display is to indicate exactly how far the rig got
through the self test before failing. Unfortunately, the codes for this
are not published. (There could be other reasons for a partial display,)

Are there separate error codes for self test from those listed in the Owners
manual - Appendix E Troubleshooting -    Error codes with the problem
defined and the troubleshooting steps?

One of the things I found was if the front panel is too far in it will short out. (On something...)
To fix the problem, I "re-nested" the 2-D fasteners after finding the front panels sweet spot.
Basically, loosen the screws a little then pull out on the front panel.
Try and power up the radio and see if the problem goes away.
If it does, torque down the screws there. You may have to reposition the panels to close any gaps.
Mine had similar symptoms to what yours is having.

BTW, I just found out that UPS ground shipping with insurance to Elecraft is about $48!!!
I think I got ripped off! I just hope the repairs are simple!

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.
 
73 es Good Luck,  Al WA6VNN

As I understand it, the Elecraft message is built up incrementally as
the early intialisation proceeds, so, if that initialisation crashes or
stalls, you can tell how far it got.

I suspect the rig will freeze with the partial Elecraft, so if it does
not, the partial message may be indicative of a problem in the hardware
associated with the display, or in the AUXBus communication between the
main micro-controller and the display controller.

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
