- The satellite uses a Texas Instruments CC1125 FSK transceiver chip
- frequency — 436.200 MHz
- 2-GFSK 9k6 baud
- Preamble — 0xAAAAAAAA
- Syncword — 0x930B51DE (in big-endian notation)
- CRC16-CCITT(0x1021). Initialized to 0xFFFF. The final XOR value is 0.
- Fixed packet size — 74 bytes
- PN9 scrambler
- CC11xx packet format length and address fields are used for our header
Almost like AALTO-1 and Reaktor Hello World. Bot we have different Syncword. (see Decoding packets from AALTO-1 ( 42775))
