Re: [Elecraft] Heil Handie Mic IC Problem

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.

 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.

 Larry,

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

 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.

[Elecraft] K3 80 Meter Receive Problem

[Larry Springer]

I have discovered that my K3 is almost completely Deaf on 80 Meters.

I just did a test with my old Icom 735 and the K3 side by side.

Switching the same antenna back and forth on the 735 the band was full of
activity.

But my K3 could only find a few weak signals.

All other bands seem fine on the K3.

 

Does anyone know if I could have done something silly in the configuration
menus that could affect 80M only??

 

Any help much appreciated I am confused.

 

Thanks

Larry K6PJ
