Audio settings

I acquired a Heil Proset with HC-5 element to use with my K3. What TX
audio settings can you recommend for this set? Thanks!

I also use the HC-5 Heil element with my K3S.

It has a lower gain than most dynamic mics, so set the MIC SEL menu item to FP H in the menu. (Front Panel, high gain preamp on). If you are using the rear panel mic jack, set the menu to RP H.

Set mic gain so that you are peaking 3-5 bars on the ALC meter when talking.

I usually talk close to the mic (Within 1” or less) for best audio quality.

With my voice I run the TX EQ flat as the HC-5 already shapes the audio.

Re: Audio settings

Hi Eric,

The K3 Owners Manual states:

"While speaking into the microphone in a normal voice, adjust MIC
for a peak ALC meter indication of about 5-7 bars."

My understanding is that ALC begins with the fifth bar just flickering.

Does Elecraft now recommend that minimal ALC rather than the
K3 Owners Manual recommended 5-7 bars that I and many other
K3 owners have used for years?

Thanks.
