Re: [Elecraft] The old mic question for the NEW KX3 owner..Sorry

Hi John,

This should get you going:

MENU Set ups for the older Heil versions of the MH3 with dynamic mic
elements:

- MENU:  MIC BTN = PTT  (not PTT up dn)
- MENU:  MIC BIAS = OFF

Wiring:

On KX3, use a 1/8 (3.5mm) plug.  Don't worry about the 2nd ring on the
picture shown in the KX3 Owner's Manual - the 2nd ring is for the up/dn
buttons.  This means we get to use the more common 1/8 Tip-Ring-Sleeve
(TRS) plug.

MH-2 pin ---  KX3 pin #
- --

  1  (MIC)Tip

  2   PTT Ring

 7,8  GND   Sleeve

So, you'd need the standard 8-pin socket to match the MH2's 8-pin plug to a
1/8 TRS plug (Radio Shack has those) and you're there.

As for someone to make up a cable for you,  here's an eBay vendor
http://stores.ebay.com/W7YENs-AMATEUR-RADIO-HELPERS?_trksid=p2047675.l2563  
- I have no experience with him - who appears to be able to do this for you. 

Cheers,

David

I think is try one of two ideas. 
1 amazon has available a 3 or 4 foot cable that has a rt angle TRRS plug on 
one end and a straight TRRS plug on the other.  Cut one end off and connect the 
cable to an XLR 4 pin plug to plug into mic. 

2 use above TRRS cable and just cut off the rt angle plug and graft it to a 
Heil cable. 

As I recall the Amazon cable was pretty inexpensive, thin and red.

 First of all, the KX3 is a sweet radio and have it running quickly with only 
 small adaptations using my old 70 yo memory
 bank from 5 years with the K3 and K2.  
 
 
 Now that I've read all the historical material debating the alternatives to 
 the MH3 hand mic
 
 I'm still not sure how to get my trusted K3 Heil with a cable adapted to work 
 with the KX3..  
 Yes, I'd like to be able to interchange the Heil GM with the HC5 cartridge 
 between the K3 and
 the KX3.  
 
 
 Using the KX3 I don't care about the up/dwn buttons but do want PTT.  So, 
 this mic jack with 
 tip/ring/ring/sleeve I would like to make up an entire new cable to go from 
 the bottom of the 
 mic  with a four pin 3.5 mm jack on the other end to plug into the KX3.  
 
 
 Is there a pre-made solution available or what is the cleanest/simplest way 
 to make a cable?  Looks like
 Heil doesn't have one.  
 
 
 Did I miss the end outcome summary for this transition to KX3?  This OT with 
 interconnects in my life
 since 1959 is getting too old to tease my brain on interconnect details. 
 Instead I prefer the bigger subjects like JT65 stability for the XV-144 local 
 oscillator.  Any Elmer's with the answer out there?
 
 
 Thanks, John Lawrence,  W1QS

Thank you for your information.  These TRRS plugs and cables are often hard to 
work with
due to the fine wire used on the computer interconnect business.  I'm going to 
explore the XLR 4 
and TRSS with plug sources.  Up here outside Southern Maine it's all about over 
the Internet sourcing.
