[Elecraft] Best Heil Element for K3

[Joe Subich, W4TV]

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).

73,
