K2 Out of Six Year Mothball with Issues

[pagoglia]

I built a K2 that included the voice option and KAT100 amplifier back in
2008.  For the last six years it has sat, seldom turned on.  Now that my
son is off to college I have had an opportunity to sit down with it and
attempt to make some contacts.

I also constructed an inverted dipole back then and it runs through an
Elecraft Balun to the transceiver. The Balun has the 1:1 and 1:4 options.

Upon powering up, both the transceiver and KAT100 come on. However, when
I press and hold Tune, whether on low power (less than 10 watts) or on
high power, I always see 2.04r on the left of the screen.  On the right
is see what appears to be an SWR of 1.1:1 when  on low power.   On high
power it varies.  The LED's on the front of the KAT100 for SWR only on
occasion light up during tune.

My transmission line runs through an MFJ 864 power/SWR meter, but the
meter needle barely moves regardless of the amount of power I apply.

I cleaned up connections outdoors on the antenna and am ready to start a
discussion with anyone willing to assist.  I am even willing to sit at
the radio and talk on the phone so it might move along before snow flys
here in central New York State!  haha.

Since the rig worked prior to the downtime, this might be a matter of
only assisting me in memory recall on how to use the rig.  It could also
be something that has occurred due to sitting for a long time.

If you can assist contact me via email or ask me for my phone number.

Thanks for listening,

Best,

Paul,

The 2.04r is the MCU version, and it will be displayed if a button is
held depressed when the K2 is powered on.  The right side of the display
is the KIOC version and in your case should be 1.09.

So look for a button that is stuck on.  If you cannot see one, remove
the metalwork from the front panel and try again.

With that button (whichever it may be) in an activated position it is
unlikely that you can do anything with the K2.  Find that problem first
before drawing any more conclusions.
