M17_ANL_v2 is a radio modem designed especially to support interaction with existing M17 capable radio terminals & repeaters. It also means packet acquisition, for debugging cases or sniffing, just for fun idk.
However M17_ANL_v2 can be used to receive and transmit raw digital data - it's by design protocol agnostic.
### Parameters
* Operating freqency range is 420MHz to 450MHz (after a few changes also another frequency bands)
* Modulation schemes selectable - 2FSK, 3FSK, 4FSK, MSK and FM (for M17 - 4FSK)
* Output power level is set from -16dbm up to 10dbm (in 0.3125 dB steps)
* Data rate is set from 0.05 up to 25 kbps (for M17 - 9600 bps)
* IF filter bandwidht selectable - 12.5 kHz, 18.75 kHz, or 25 kHz

### Most important ICs used in project
* STM32F303CBT6 - MCU which controls data flow(PC <-> RF TRX), and radio parameters.
