There have been periodic reports of incompatibility between some paddles
and WinKey. This appears to be due to the use of "new" contact materials
designed to reduce oxidation issues. Some of these materials create other
than perfectly conducting contacts ... even semi-conducting contacts.
To accommodate these new paddle designs, K1EL and microHAM have cooperated
to produce a "paddle processor/debouncer." The debouncer uses a micropower
PIC with independent, high threshold inputs to sense the paddle state.
Paddle
closures are processed with an advanced debouncing algorithm to remove all
"noise" on the inputs and passed on to the keyer as unambiguous levels.
The debouncer is now available in two versions. Both versions have 20 cm
output cables terminated in a standard 1/4" stereo plug to connect to a
microKEYER, CW Keyer or K1EL WinKey kit. The "Begali version" has a one
meter long input cable terminated in a 3.5 mm (1/8") stereo plug which
connect directly to the paddles. The generic version replaces the 3.5 mm
plug with a 1/4" stereo jack.
Limited quantities are available now at http://www.microHAM-USA.com
Additional cases have arrived from the vendor and more units are in
production.
