[Elecraft] K2 - PSK31 question

[Don Wilhelm]

Tom.

You either have the microphone configuration header that was indtalled 
as a part of the KSB2 option or you do not have the KSB2 option installed.

All properly constructed K2s with the KSB2 optionl 9  will have that 
Microphone Configuration Header on the Front Panel Board.  It is not a 
consideration for the serial number of the K2, that jumper became 
available at the first time the KSB2 was made available and is 
applicable to all K2s.  I have K2 SN 00020 and have the microphone 
configuration header installed (part of the KSB2), and I have no problem 
interfacing with any ham microphone - pro-audio mics requiring phantom 
power are a different matter entirely.
