K2 microphone wiring for TenTec 705

[Mike Geddes]

Greetings Elecrafters. I have ordered a TenTec Model 1201 microphone kit for
SSB use with my K2.  It is an electret mike, and is their kit version of the
705 desk mike.  I liked the looks of it and understand these mikes work
pretty well with the K2.  My questions:  Does it connect to P1 using the
ICOM configuration? Does it require the resistor?

Also, is there a location on the Elecraft web site that shows microphone
connection configurations beyond those listed in the KSB2 manual? The manual
kind of alluded to that, but I could not find anything on the web site.

As usual, thanks for any information and assistance you can provide.

73,
Mike

Mike:
If it's an electret mic, it requires power.  Assuming the power is
coming from the K2, then it needs the resistor.  The 1201 mic kit
doesn't come with a connector (I just checked), so you are free to wire
it any way you want, after you buy the proper connector.  Just make sure
the K2 is configured the same way you decide to wire the mic.  If the K2
is your only radio and the 1201 is your only mic, any random
configuration would work, but it makes a lot more sense to wire both to
some standard, usually ICOM or Kenwood.

Mike,

I briefly had my hands on a TenTec 705 microphone.  It had a battery in
the base which causes me to believe that the electret element is powered
from the battery.

In any case, a review of the schematic should reveal how the various
connections (AF, PTT, 5v, ground, etc) are routed to which color wire.
I did not find a schematic at the TenTec website.

Wire the 8 pin plug to any configuration that you want.  If you have
other mics in the shack, make them all the same, but if this is your
only mic, then I recommend the Elecraft wiring configuration with Icom
and Kenwood as secondary choices.

The KSB2 manual covers all the common mic plug wiring schemes.  I have
not seen additional information published.

BTW, that TenTec 705 was a great sounding mic.
