[Elecraft] K2 SSB module help

[Robert C. Abell]

Eric,
I am having trouble to get my K2 S/N 2062 to accept  PSK-31 modulation 
from my computer. It worked fine until I installed a MH2 Heil microphone.
Your reply to Terry, W0FM of 11/23/03 about having to be sure that a 
5.6K resistor was installed between pins 1 & 6 of the mic plug twigged 
as to possibly why my PSK-31 mode is no longer working. As indicated it 
worked just fine before adding this resistor to use the MH2 mic.
To save me the trouble of tearing the rig apart and removing this 
resistor to try it, perhaps you could offer your opinion as to whether 
this is my problem.
Thanks Eric and anyone else who may be able to offer an opinion.
