1 - it is necessary for a reader to distinguish the difference between statement "compatible" and statement "fully compatible".
     SoftRF implements only a reasonable minimum of the protocols specs. No "bells and whistles" so far.
2 - FANET+ can not receive FLARM. However it is able to transmit it.
3 - valid for Prime Mark II , Dongle , Mini , Badge , Bracelet , Academy , Octave , Lego and Balkan Editions; valid for Standalone , UAV and Uni Editions with optional DIY SoftRF LoRa RF module
4 - Reception of traffic 'downlink' frames only. Valid for Uni Edition alone and for Standalone Edition with optional DIY SoftRF UAT module
5 - Reception of traffic 'downlink' frames only. Valid for ES Edition
6 - also known as "raw ADS-B"
