[Elecraft] K3 + Heil HC 5 element

[Joe Subich, W4TV]

John,

When I had the Proset with HC-5 element I used almost the same TX EQ as
I currently use with the CM-400 - just a bit less preemphasis at the
high end.

The HC-5 settings were:

     50  -16
    100  -16
    200   -6
    400    0
    800    0
   1600   +3
   2400   +5
   3200   +6

Effectively, 65 db/octave roll off below 400 Hz to reduce the bass
boost from having the mic close to the mouth and a 3 dB/octave boost
above 800 Hz.  With the CM-400 or other mics not designed with an
"articulation peak" at 3 KHz I increase the pre-emphasis slope to
6 or 9 dB/octave (6dB/octave is usually sufficient unless the mic
has a severe high frequency problem).

73,

    ... Joe, W4TV
