Use your imagination to create your perfect paddle.
Create your own set of touch paddles using just about any conductive metal and wire
them to the model P3 circuit card. (up to 24″ away)
Model P3 circuit card is so small (ONLY 1.15″ W x .815″ D x .4″ H)
it can fit inside most homebrew equipment.
Operates on 6-14 DC volts. Positive Keying of 13.8 Volts or Less.
Paddle separation: > .25″ (To prevent capacitive paddle interaction paddles should be separated by a minimum of .25″.
However, this specification will vary with paddle size.)
| Output: | Open dran FET. +13.8 volts, 60 mA or less. |
| Non-touched paddle | Infinity Ohms |
| Touched paddle | <5 ohms |
| Output Response | Directly proportional to the paddle touch time. |
| Paddles must not touch any other metal object! | |
Can be used as a STRAIGHT KEY also. Simply use just one paddle, connect it to your “key-in” point and tap away on your code. | |
This product is ideal for you to use your creativity and talent in developing your own unique paddles.
NOTE: The keyer output transistor circuit is designed to switch key input of 13.8 Volts positive or less. Do not attempt to use any CW Touch Keyer products with a vacuum tube transmitter (either grid blocked or cathode keyed) without an appropriate output circuit.
