So here they are! Capacitive CW touch key for KX2 or KX3.
This is the second version.
The first version did not stand the test. With a nearby transmitter, interference was induced. The device gave false signals. I reworked the circuit of the device. I also redid the Board layout. An active protective circuit has been added. Now the device can withstand the high-frequency voltage of my 1 kW amplifier with a bad SWR.
Advantages of the device:
- no mechanical moving parts,
- does not need adjustment,
- not afraid of dirt,
- speed depends only on the speed of your fingers,
- consumes very little power.
Disadvantages of the device:
- you can't work with gloves on.
Video of the device can be viewed on Youtube.
I'll send you the key fully assembled and ready to go. Also included will be 2 bolts for mounting. No modification of the transceiver is required.
