Ian,
It is likely as you suspect, but opening the path to the microphone jack
is easy.
Remove the jumper from the AF signal on the microphone configuration
header and re-check just to be certain.

On completing the resistance tests for the Front Panel Board on page 29 of the

I think this is because I've got the KSB2 option and following instructions on
page 29 on the K2 manual, leading me to pages 16/17 of the KSB2 manual, I added
the 5.6k resistor between mic pins 1 and 6, with all the jumpers ready for the
MH2 mic.
Looking through the archives for clues, I see that on 3 Nov 2012 VK4HD, David,
posted the same query with the same resistance reading. Don asked him to check
for solder bridges.
Is this a minor oversight in the manual? A note saying "J1 pin 5 will be 29k if you
have installed the jumpers and 5.6k resistor in preparation for the KSB2 and MH2
mic" would clear it up if I'm right. But maybe I'm not, as only VK4HD and myself (as
far as I can tell) have posted this query on the Elecraft list.
Have I missed something...?
