Re: [Elecraft] Need Mic adapter: Icom SM-50 to K3 mic input jack

[Pete Smith N4ZR]

Or... you can use the standard stereo mini plug which is usually 
supplied with condenser mikes and plug into the mic jack on the rear of 
the K3.  I use a Yamaha CM550 and it plugged directly into my K3 - just 
had to remember to enable bias on the rear mike jack.  I don't know 
which flavor of mic those two are, but page 28 of the K3 manual (and 
nowhere else I can find) explains what to do.

The Elecraft pin 6 carries +5 volts while for Kenwood, the +5 volts is 
on pin 5.

Pin 5 for Elecraft is the Function button.

If your microphone does not require +5 volts and does not have buttons 
other than PTT, then you only have to be concerned about pin 1 (AF), 
pin 2 (PTT) and pins 7 and 8 (one for PTT return and the other for AF 
return - both are connected together inside the K3).


Icom and Yaesu are not as straightforward, see the G4WPW info at 
https://www.qsl.net/g4wpw/date.html for details on the pinout for 
those mics.


If you can do a bit of soldering, you can make and adapter for the 
price of a male and female Foster connector and a bit of wire.  If you 
rewire the Foster connector on the mic, you don't need any adapter or 
connectors at all, just a bit of solder, to unsolder the wires from 
the existing connector and solder them in the correct pins for the K3.


OTOH, if you wish to switch back and forth between the Icom/Yaesu 
pinout and the Elecraft, the adapter or the MFJ box would be the best 
choice.

I have no microphone for my K3. I am usually on CW or the digital modes.
Now I want to get on the KY Phone Net on 3838.

So I talked DXEngineering and they know of no adapter plug/cable.

So, I have an Icom SM-50 mic  and a Yaesu MD-100 mic.

Anyone know of an adapter connector that would fit either to adapt 
them to the K3?
Or maybe a universal box that lets me plug all the mic's in and have 
a cable to the K3 

Also run an Icom IC-9700 FWIW.

[Raymond Sills via Elecraft]

Or for $70, you could buy the MH4 mic from Elecraft.  Works with the 
K4,K3S, K3 and K2.

You will have to either rewire the Icom mic's Foster plug or you need to
purchase the Foster plug adaptor for the Yaesu mic and then rewire it.

[Elecraft] Need Mic adapter: Icom SM-50 to K3 mic input jack

Hello Elecraft List

I have no microphone for my K3. I am usually on CW or the digital modes.
Now I want to get on the KY Phone Net on 3838.

So I talked DXEngineering and they know of no adapter plug/cable.

So, I have an Icom SM-50 mic  and a Yaesu MD-100 mic.

Anyone know of an adapter connector that would fit either to adapt them to the 
K3?
Or maybe a universal box that lets me plug all the mic's in and have a cable to 
the K3 
Also run an Icom IC-9700 FWIW.
