[Elecraft] K2 - PSK31 question

[Tom McCulloch]

Hi gang,
   I have a very old Rig Blaster interface that uses jumpers to match 
the transceiver's  microphone to the Rig Blaster outputs.  The 
instructions are quite old and they don't list the jumper configuration 
for Elecraft rigs.  I seem to remember that the K2 mic jack is 
configured the same as a Kenwood.  Could someone please verify this for me.

Also, is there anything I should know about running psk31 with a 
barefoot K2?

Thanks in advance.
