[SJDXA] We had a K3 go down during the Ph Contest

[jeff kb2m]

 Thanks Bob. I  picked up the K3  on the way home from work yesterday and
worked with Dale on the phone after I got home going through the config
file, internal wiring, etc, after I had a problem performing the TX
calibration test. He then asked me if I  had a scope ,and a signal source to
continue. I told him , yes but I was darned if I knew where my scope and XG2
were, there is a big pile of 30 or so boxes of my hobby stuff in the
basement and main attic of my new house.  At that point I called Bob and he
graciously agreed to continue diagnosing the problem.  I dropped the K3 back
off at his place after work and by the time I arrived at the GF’s in Reo
Grande the problem was found!

  As Bob is doing the work for the club Pro Bono, I will also, paying for
any parts needed, so the repair will cost the club nothing.  I’m now feeling
much better, I missed work all last week, and the weekend contest, but now
back in business.

To the SJDXA,
At the start of the Phone CQ contest this past weekend, we had a problem
with a K3 owned by Jeff, KB2M. Jeff had me call Dale at Elecraft today
because I have the test equipment to trouble shoot the rig.
Dale had me look at a resistor on the bottom of the main board, the resistor
had let the smoke out. The cause was a shorted IF amp transistor, this
happens when the RX gets high RF on the RX antenna. There is a mod to
monitor the amps current and turn on the Attenuator during high levels of
RF, KB2M rig did not have the mod.
Dale of Elecraft is sending the parts and the mod. If there is a charge for
the parts, I will pay it on my Credit Card and then ask the club to
rein-burst me.
I will do the mod and change the bad parts, of course at no charge to the
club. But Jeff owns me:).
73,
de Bob, W2ARP
 PS we own Dale at Elecraft a big Thank You for the great service that he is
giving us.
