Firmware for the RF Signal Generator [0410619A.HEX]
ATmega328P microcontroller firmware (HEX file) and BASIC source code for the AM/FM/CW Scanning HF/VHF RF Signal Generator (0410619A.HEX).
Update: this new version (V14) suits both pulse-type and level-type rotary encoders. You can identify a pulse type encoder as the two internal switches are always open when the encoder is at rest, while a level-type encoder will have one or both switches closed in some rotational positions. If your encoder is a level-type, solder a 100kΩ resistor from pin 28 of IC1 to GND to enable correct operation.
