K3: ModMic boom mic

[Edward R Cole]

Quick report on AntlionAudio ModMic:

I bought model 5 which has both omni and cardiod pattern mic
elements.  After a little K3 Manual study: page 55 for MIC SEL options
I chose to try using the 3.5mm rear mic jack; ModMic comes with
stereo 3.5mm so questioned if it would work in mono jack.
tip = cardiod element
ring = omni element
base ring = ground

I checked on-line to find that both require 1-10v bias so 8v bias
from K3 works great
MIC SEL: rP.L biAS
tap 2 to toggle bias on
tap1 was left in Low

How to key radio:  rear PTT IN (female RCA-Phono) not in use with my radio
Alt key;  My Heil CM10 desk mic has a breakout with 1/4-inch phono
receptacle for a foot switch - used that (works whether front or rear
mic selected)

So I key the radio, observe ALC and RF power on a Bird and va la
there is modulation.  Level is higher with omni element selected.
No "on-air" quality test at this point.

I attached the boom mic to my "old trusty" SONY MDR-V600 stereo
headset.  Neat part is boom is held with a strong miniature magnet so
easy to remove mic and store In nice foam zippered case supplied with
the ModMic.  Also has mic mute button and extension cord, spare
stickered bases and cable clips.

Next to test with KX3 (I will need four ring wye to two 3.5mm jacks
extension - I believe obtainable from Elecraft).

PS: CM-500 still in transit

Ed:
Also spend some time with the TX EQ settings on your K3.  I had the help
of a couple friends who know my voice very well.  I don't remember the
exact numbers but the 2 or 3 low frequency bands were rolled off a bit.

I've used this mic in various contests for about 3 years.  Always get
positive comments about excellent audio.
