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.

Tom, WB2QDG
K2 #1103

The K2 has internal jumpers for the mic jack configuration. This allowed for
the use of almost any microphone. I suggest you open yours to see how it is
wired. Refer to the manual for the layout of the configuration header.

Thhanks Bruce -- I think I have an older K2 (s/n 1103) that doesn't have
the jumpers -  The jumpers are a good idea, it good to see they've
incorporated them

Tnx

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.

Sorry that the other replies misinterpreted your question.

I run an "old" RigBlaster Plus with my K2, and the RB should be jumpered
for Kenwood 8-pin round if your K2 is set correctly.  I don't have the
manual handy but it should be av available on line from the WestMountain
site.

Have fun!
