monoprice.com has a good selection of these type of adapters at appropriate 
(for high volume Chinese) prices.

As far as I know, the only headset/mics that need an adapter would be 
those that have a single Tip-Ring-Ring-Sleeve (TRRS) plug. The Star-Tech 
MUYHSFMM adapter looks like the right part. A search for that part on 
amazon will find it.


In the KX2 and KX3, the mic jack is TRRS, but the two rings are used for 
logic switching with an Elecraft mic (PTT, up/down). With any other mic 
(including one using this adapter), we need to go into the Menu and set 
MIC BTN to "Off" and set the radio to use VOX (or use the XMIT button).

Headsets are something that we need to try on, like a pair of shoes -- 
it essentially comes down to physical comfort. It's hard to buy 
something online knowing what it will feel like. :) I'm primarily a CW 
op, especially QRP, and I'm old enough that backpacking doesn't apeal to 
me, so I've never bothered to look for a backpacking headset/mic. For 
lightweight headphones, I like the Etymotic Research and Shure in-ear 
products.


TXEQ in Elecraft radios is so good that virtually any mic that isn't 
"broke" can be made to sound good.

Agreed.

You will want a housing with pop suppression, 
so your breath won't make an
objectionable pop when you exhale or say 
certain phonemes.


I disagree with this. The correct advice is to 
avoid microphone TYPES that are subject to 
breath pops, and to use the mic you have so that 
your voice doesn't generate pops. So -- 1) avoid 
directional mics and noise-cancelling mics, both 
of which are subject to breath pops; 2) position 
the mic a few inches above and to the side of 
your mouth. The boom mic of a headset makes this 
VERY easy.  The Yamaha CM500 and Koss SB35 are 
good choices. See the photo on page 5 of 
http://k9yc.com/ContestAudio.pdf  for an example.



  You need to
decide between hand-held, desk or boom mount 
and a mic attached to a
headset. And you'll want a connector wired for 
the K3.


I find a boom mic headset ideal for operating 
SSB. The CM500 and SB45 plug straight into the 
rear panel of the K3 and K3S. They are very 
comfortable, and both mic and headphones sound 
great.


Elecraft makes a nice set of mics that take all 
the hassle out of having the
right connector and of course the company 
stands behind them. (In "full
disclosure", I'm not an employee, but have been 
associated with Elecraft for
16 years so far. That has given me the 
opportunity to use several of their

mics.)
I love the guys at Elecraft, but I don't 
recommend the mics they sell, which they buy 
from third party vendors, and must sell at a 
significant markup. Elecraft is in the RADIO 
biz, and they're really good at it. Those Yamaha 
and Koss boom mic headsets offer FAR more value 
for the money. If you want something more 
compact to carry up the trail with your KX2 or 
KX3, look at lightweight computer headsets, 
which plug into those radios directly, or with a 
simple adapter you can buy on amazon for $5.

Re: [Elecraft] [K3] microphone question

[Don Wilhelm]

Kenwood dynamic microphones will work fine in the K2 - just turn the 
bias off.

Use the 600 impedance setting.  The 50k is for tube mic preamp inputs.

Is this a suitable mike for the K3?

If so:

Is it better to use it at 600 or 50K impedance?

[Elecraft] K3 Microphone question...

[Phil Townsend]

Is it OK to run BOTH front and Rear Microphones. I want to have the MH2 mic on 
the front panel and my boom mike on the rear connection.
The rear mic is Recording mic I rebuilt.
I want to be able to run either one. Not at the same time…duhhh.
Thanks for the help...

Phil,

Certainly you can connect both mics.  The menu selection will determine 
which one is to be active.

[Elecraft] K3 Microphone question

[Barry McWilliams]

The wiring for the K2 MD-2 microphone and the Heil headset has 5V 
applied to pin 1 through a 5.6k resistor.


Will the K3 supply 5V on pin 1?

Thanks, Barry (WK2S)
