Dear OMs and Yls
Can someone tell me for what serial number the change to Gold plated
pins was made for the K3.I note that David found it necessary to do this
for SN 4474. I have two K3s one 2574 and the later 5487.I thought they
were both using gold plated pins.I could take the older one apart to
check but it would be nice to know the cutoff SN for gold plated connectors.
I did check the Elecraft site and am unable to find the answer let
alone the upgrade kit though I can find plenty of other updates.
Thank you to whoever answers this query.

Subject: [Elecraft] K3 TX calibration fails after KXV3B and SYN3A upgrade
I'm hoping there is a quick fix for this (some fat-fingering or brain
fade
on
my part is entirely possible) as the K3 in question is one of four
heading
to E6GG next month.
Yesterday I upgraded S/N 4474 with KXV3B and 2 x SYN3As and while the
panels
were off, also did the 12V DC Out mod and gold connector replacement mod.
I
have a full ESD bench and wore a wrist strap at all times.
After careful reassembly and TMP cable checks, I was able to update to
latest firmware and enable synths and KXV3B. But TX Calibration failed
with
Calibration power settled at0W; message.
I have tried the following remedies:
Panels off and examined all boards for correct seating.
Examined all TMP cables for correct seating.
Replaced panels.
Re-attempted Calibration - same error.
Re-flashed the firmware load. Load successful.
Re-attempted Calibration - same error.
Performed EE INIT
Loaded a known-good prior configuration (from March 2015 well before the
upgrade)
Re-attempted Calibration - same error.
Any suggestions for next steps gratefully received!
