K3: Anyone have any troubles with latest 4.86 and RemoteRig TX audio?

[Hisashi T Fujinaka]

I had a bit of trouble getting my mic audio working initially, but with
Brandon's help it was working. After updating my firmware it's back to
having no audio. I can change MIC SEL to FP and still run the K3
directly, but with it set to rP I don't get any audio at all.

Anyone else have this problem and have a fix? I'll have to call Brandon
tomorrow to figure out what all the steps are to get tx audio working. I
forgot to write them down.

Thanks.

Does your rear panel microphone need bias?  If so do you have the bias
set ON?

I've tried it both ways, and as I said, I did have it working before the
firmware update. So here's the oddity:

My headset is the Heil that I bought from Elecraft for the K2. It should
NOT need bias as far as I know. I just checked the MIC SEL and when I
have it on FPL, I do have the .bIAS. However, since I thought it didn't
need it, I did change the jumper in the RRC-1258 MkIIs to turn off the
bias. Could that be the problem?

Thanks Don.

The Heil ProSet-K2 (sold by Elecraft) has an electret element, and
*does* need bias.
Turn Bias on for the rear panel connection and it should work (or set
the jumper in Remote Rig to provide bias if you are plugging it to the
RRC box.

Well that was the problem! I wonder why I thought it worked before.

The reason I changed the jumper is because of the RemoteRig users
manual, that says:

  Control-RRC only: JMP-1 is placed behind the TTL connector. With the
  strap in place a DC voltage is feed to the microphone element. All
  ICOM microphones should be DC-feed.
  Dynamic microphones like the ones used by Kenwood should not be
  DC-feed. HEIL microphones should not be DC-feed either.

Maybe they just mean the desk microphones.

No, they're incomplete.  Heil dynamic microphones (HC4, HC5,
HC5.1, HC6, "Classic", etc. elements) should not have DC.
*However*, Heil 'iC' elements *must* have DC (bias).

The Heil/Elecraft Proset K2/K3 is the same as the Heil
Proset iC (Icom) - the only difference is the use of the
AD1K (Kenwood adapter) versus the AD1I (Icom adapter).

Be careful with that statement about Heil microphones.  The ones for
Elecraft and Icom have electret element and need bias.  There is one
newer Heil element that is electret - I can't recall its designation.
Yes, most Heil microphones are dynamic, but there are many exceptions.
Simply saying the microphone is a "Heil" is insufficient, one must be
explicit about the exact model and the adapter used.
