I get lots of compliments on my audio, using a "computer" head set that uses
an electret mic. You can spend up to $15 at R.S. and get a nice one. At
the local big box electronics store, I saw sets with leather like ear pads,
or foam ear pads. I borowed a Labtec from a friend and tried it out and was
happy with that as well.

I find it much easier than using a desk mic. Since your mouth is always the
same distance from the microphone you can have better audio and not have to
play with the Mic Gain on your radio very often.

You can see the one that I use on QRZ or at

One of the Ham Radio Magazines ran an article in the last couple of years,
showing how to use plastic pipe fittings to mount the element and make a
desk stand.

I have used my "desk mount" Sound Blaster microphone, You can get them at
ham fests or flea markets for $3.00 or buy a replacement at your local big
box electronix store for about $10.00

Here is a schematic of how I added the proper voltage to my radio.

Those PIN NUMBERS apply ONLY to a Kachina 505DSP.

I used the same head set in My Alinco (DX-77T), There was already a power
supply on the board all I had to do was install a jumper to liven up the
mic. Most ICOM radios are powered.

Good luck.
