K2 and RF-clipping

Benny Aumala

In stead of modifying the well-designed interior of K2,
the clipper can be external. Look at www.qsl.net/df4zs
where a small print is inside the microphone itself.

Having access to + voltage, mic can have a genuine RF-clipper
built inside (AF-filtered SSB-clipper-filtering-prod.det-AF).
Hence, the same mic can supply correctly cipped speec to
any rig.

Another thing: see that your microphone capsule can be used with
RF-clipping. I have tested, every time a new clipper is installed,
by listening the result. A 6dB/octave roll-off of low frequencies from
1kHz down seems to be necessary before balanced modulator.
My tests have always ended to BROWN 2" military dynamic capsule
or HEIL units (where preaccentuation is already built-in).
Result: Heil always because of size.
