Mic for K3

[Tom Brereton]

Hi All,
I have access to a Kenwood MC-80 (made for the Kenwood 850).
Is this compatible with the K3?

Tom,

The K3 is wired for the *now* Elecraft standard mic pinout.  It happens
to be *compatible* with the Kenwood pinout (except for pins 5 and 6).

You should look up the pinout (and pin usage) for any microphone that
you would intend to use with the K3 (or any other transceiver), and know
the usage of all the pins.  If it maps to the the Elecraft pinout, then
it can be used, otherwise the connector plug will have to be re-wired.

I can say that if any Kenwood mic does not connect anything to the  
Kenwood defined +5 (or +8) volt pin (pin 5), and does not connect
anything to pin 6, then it will be compatible with the K3 pinout.

User, know your microphone.  There is information on the web - Google is
your friend.  The Elecraft pinout information is in the K3 manual - we
cannot be expected to reliably know the details and eccentricities of
every microphone out there, but I can state for certain that the
Elecraft MH2, MD2, and Proset K2 will work just fine with the K3.

K3 with    Yet ANOTHER non-standard mic pin-out.  Now ham radio has at least 4, and with Ten Tec, maybe a fifth.
Then there was the TR-3/4 which took a SMALLER "1/4" phone plug.... like Collins; and
the old 4 pin plug, too....... ENOUGH !!!!!!
 
Manufacturers:  Hams usually do not purchase a mic just because of the plug.... GET A UNIVERSAL PIN OUT STANDARD, PLEASE! and stop trying to sell your unique mic/plug.Charles [hidden email] > Date: Wed, 13 Feb 2008 00:24:41 -0500> From: [hidden email]> To: [hidden email]> Subject: Re: [Elecraft] Mic for K3> CC: [hidden email]> > Tom,> > The K3 is wired for the *now* Elecraft standard mic pinout.

The MH-80 is a "powered" microphone.  It uses either a battery or
power from Pin 5 to bias the electret mic and operate an internal
preamplifier.  Preamplifier output level by a pot at the output
with no DC blocking capacitor.  

I would be very wary of using the MH-80 with the K3 unless the
mic cable were rewired and a blocking capacitor was put in line
with the wiper of the output level control.

The web site: http://homepage.ntlworld.com/rg4wpw/date.html is
an excellent source of information on radio microphone connections
and information/schematics of most OEM microphones.

Hi Charles,

We have been using this pin out for microphones on our rigs since we
introduced the K2 nine years ago. It is 100% compatible with Kenwood
dynamic microphones in addition to ours. It was picked so there would be
a wide range of existing mics you could use right when we introduced the
K2. We just continued it on the K3 to maintain compatibility with our
prior microphones etc. I personally have Kenwood hand mics from my
TS-950, VHF mobile rigs and a MC-60 desk mic that work well with the K2
and K3.

dynamic microphones in addition to ours.

I've been using Heil headsets since they first came out (1980's).  I've gone through the following rigs with the BM10 and Pro-Sets (and a mixture of HC4 and HC5 elements):

Kenwood TS-930S
Yaesu FT-1000MP
Ten-Tec Orion
Elecraft K2 and K3

The Elecraft is the first rig I have **NOT** had to buy a new adapter for.  I simply used the one I've  had for Kenwood since 1984.  Everything works fine including the footswitch input.  

Thank you Elecraft for using the Kenwood standard instead of creating yet another!

And if nothing else, the K3 manual has been out since September or October.
While we all waited (and continue to) for our K3s, there's been plenty of time
to examine the diagrams and instructions to figure out just what will be needed
to interface the K3 with our individual stations.  I'm not trying to be
condescending, but even if the K3 had a completely new mic pinout, there's been
plenty of time to prepare for it, if one so chose to do so.

when i wired both my k2 for Icom mics.... everything was working fine till.....
I used the icom  sm-8  .It also grabs dc from the up/down circuit to
power the mic, rather than using the dc bias on the audio line. Had
no audio and it took me a while to figure it all out......

and my k3 ( in my station) feeds THRU THE BACK CONNECTORS......
I have 2 GREAT shure 414b mini hand mics... 1 wired K3  one for the
IC wired K2s.

8 band modes so far for VP6DX..( K3s)..  still looking for 40 & 80..
