[Elecraft] Heil HC-7 Dynamic Element with K3/0 Setp

[Ken via Elecraft]

Aha - two questions at once.
My instruction manual says to tap [3].

"
For the front-panel mic only, additional microphone
gain can be enabled by tapping 3 . Use this only for
very low-output mics.
"
I also tried 4,5, and 6 . . . I should have kept going  :-)

I asked Elecraft about this. Apparently it is an error corrected in the
"errata" document. Sigh.

Anyway, yes, with this boost function I can run the mic gain around 30 and
even with FP.L selected.

Thanks,
Ken

Hello Ken,

I use the Pro 7 w/ the HC7 element as well.

Tapping the "7" key while in "MIC SEL" will bring in the extra preamp which
in combination with FP.H will most likely be too much gain. If it is, try
leaving the "7" preamp engaged but drop back to FP.L and see if that gives
you enough gain. I would NOT suggest using both the "7" preamp and FP.H
though.
