Heil Handie Mic IC Problem

I have used the HEIL Proset with the IC microphone since I buught my K3 with excellent results.
I decided I wanted a desk Mike so I thought the HEIL Handie Mic IC should give me similar results.
So I bought a Handi Mic IC and CC1K cable. I get no audio into the K3 with this combination.
Is anyone using this combination with the K3?
Should it work?

Does anyone know the wiring of the 4 pin connector on the Handi Mic IC?
I cannot find it on the Heil web site.

73 & Thank You

Larry,

See if this is it. The K3 uses the same connections as Kenwood.

Re: Heil Handie Mic IC Problem

Actually, this sounds like a question that should be answered by
Heilsound. You may have a non-working microphone or you my have an
adapter that will not work with the K3.
Both the ProSet-iC and the HandiMic-iC should need bias if I recall
correctly.
The K3 provides bias on the AF pin, and that Kenwood cable may include a
blocking capacitor (which would render the K3 bias ineffective) and
depend on the voltage at Kenwood pin 5 to power the element (the K3 has
voltage on pin 6).
What I am saying is that only Heil can provide the right answer - they
do not publicize the schematics for their adapters and cables.
Unfortunately, HeilSound in the past has stated that Elecraft is the
SAME as Kenwood, but actually it is not the same - it is "compatible"
but that does not make them "equal".
The difference is in the use of pins 5 and 6 on the mic connector.
Elecraft uses pin 6 for 8 volts, Kenwood uses pin 5 for 8 volts.
Bottom line - any mic (or adapter cable) that depends on the Kenwood pin
5 voltage will not work with the Elecraft pinout. As one "for
instance", the Kenwood MC-85 microphone will not work with the K3 for
this very reason.

Don

Thanks for the response.
Yes, I found it very frustrating that Heil does not document their wiring.
yes for the Proset -IC the Bias is turned on.
I tried E-mail to Heil but got no answer.
Your idea on a blocking cap could explain what I am seeing.
I think I might ring out the adapter to see if it is using the bias in pin 5.

In reply to this post by Mike Reublin

I use both the Hand mic and the Heil headset and boom mic from Elecraft, There is no noticable difference between the mic's, no settings need to be changed in the menu's.

Re: Heil Handie Mic IC Problem

I did some measurements and I think the HandMic IC that I have may be defective.
The IC element in my Proset measures 2.35 kohms.
The IC element in my new Handi mic measures 29 kohms.
