The RF Sensing Band Decoder is a device designed to decode radio frequency signals in the band used by ham radio enthusiasts. It is specifically tailored for ham radio amplifiers, providing a means to accurately interpret and process the signals being transmitted. This technology can help improve the functionality and performance of ham radio equipment, allowing users to better communicate and operate within the designated frequency band.

Please decide the output mode :

- Active High, or

- Active Low

How it works

  1. Wait for PTT (GND active) to be activated
  2. Once PTT activated, wait for RF to appear
  3. Measure incoming RF
  4. Set the output according to measured frequency
  5. LPF relay activation 10ms time delay
  6. Set output PTT (GND active)
  7. Wait for PTT to be released
  8. Go back to waiting for PTT
