[Elecraft] RF-clipper
Instead of modifying the well-designed interior of K2, the clipper can be external. Look at www.qsl.net/df4zs. I have 36x27 mm print INSIDE THE MICROPHONE itself. Of course it is a 10mA miniversion, but a genuine RF-clipper with two filters,3 ICs and 3 potmeters. Variables are input, output, pitch (oscillator frequency = passband tuning). Should df4zs invent it again? Another thing: take care your microphone is compatible with RF-clipping. I have tested, every time a new clipper is installed, by listening the result. Normally I had more than 6 mic candidates. A 6dB/octave roll-off of low frequencies from 1kHz down seems to be necessary. My tests have always ended to an old BROWN 2 military dynamic capsule or HEIL units (where preaccentuation is already built-in). Result: Heil always because of size. -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] RF-clipper to K2
That looks perfect Benny, no matter where you mount it. Larry N8LP Benny Aumala wrote: 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.
