Best Heil Element for K3

I have a new Heil ProSet 7 with the regular HC-7 element. A friend of mine told me that that is the wrong element and that I should have gotten the IC electret element.
In fact, he said that Elecraft recommends the IC element for the K3. Is this true? What has been anyone's experience with the IC element and the K3?
Thanks, Dave, N8NB

Dave,

Since you have the K3, your microphone should be fine - just turn bias OFF.
The K3 has adequate mic gain range to handle most any microphone. I
believe the HC-7 element has relatively low output, so you may have to
use the High mic gain range.

Your friend may be remembering the K2 which had limited microphone gain
and did not do well with low output dynamic microphones.

Elecraft does sell a Heil Proset-K2 with the iC element. However, like
any electret element it requires some TX EQ to be effective. The low
end typically needs to be rolled off [-6 dB @ 200 Hz, -16 @ 100 and 50
Hz] to prevent "rumble" and wasted transmit power while the high end
generally needs boost [+3 dB @ 1600, +5 dB at 2400, +6 dB at 3200] for
"articulation" (as paging and PA system designers have known for
decades).

The HC7 has that contour already 'built-in' - the only thing needed is
to disable the "bias" (DC voltage) on the mic jacks and select a little
higher gain for the mic preamp (an electret has about 26 dB more output
than a dynamic mic like the HC7).

Hi Dave,

I got the same headset, and it would not work with the remote setup using the K3/0 mini to connect to a remote K3 with the RemoteRig system linking them. There was way too little mike power to move the needle. I then bought the Pro-Set that Elecraft sells, and it came with the little "iC" sticker indicating the Icom version. I sent my Pro7 back for a swap of elements to the iC electret, and everything worked fine. BTW, the Elecraft hand mike (MH2) also worked fine, and one of the guys at Elecraft told me it had an electret element.

That said, I am certain the same problem did not occur when using the mike with the K3 itself. Plenty of gain with either version mike.

I use a Heil Proset Elite and I have had consistently good audio reports. It has more than adequate gain for the K-3. I have also used a Heil PR 40 to very good effect. As someone mentioned, neither of those microphones require bias and so it should be turned off.
