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).

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.

The Heil ProSet-K2 (sold by Elecraft) has an electret element, and

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.

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?
