[Elecraft] K3 - Rear panel mike socket; stereo or mono?

[stewart rolfe]

Been trying out a pc type headset with boom mike and a
3.5mm stereo plug on the mike lead. Having what I like
to think of as a logical mind(?), I made up a 3.5mm
stereo to mono adapter to plug into the socket on the
rear of the K3 which is labeled 'mono'. This 'sort of'
worked but kept losing the connection intermittently.
The adapter plug did seem to be a bit of a loose fit
which caused me have a closer look at the KIO3
analogue board and I noticed that the mono mike socket
appeared to be a stereo type with presumably, just the
tip connected. 

Anyhow I just plugged the stereo plug from the boom
mike straight into the 'mono' socket and it works
fine, better fit too. Can't find any mention of this
in the manual so wondering if the use of a stereo plug
is the recommended way...?

PS. The VOX on the K3 is a joy to use.....
