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 and Lego 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"
