Carl Ott, N2RVQ has created a nice encode for the Arduino platform. Here you can download the HEX file for this encoder: pocsag_transcode_m328_3_24_arduino
A good application to zap the HEX into the Arduino is ‘ArduinoBuilder’. Link
- Pocsag encoder;
- Pocsag decoder (test phase);
- CW identification;
- 5 predefined POCSAG messages.
