Remote Keypad

This is a sample of the keypad. A homebuilt model is described in QST Feb 2000.(ed.)

The circuit for the keypad is very simple. A wire comes into the keypad and is connected to ground through 12 different resistors and 12 switches. I can give you the resistor values for each button if you don't have them already. Lou W7DZN
