 ===== What is packet radio? =====
-Packet radio in the context of amateur radio has historically revolved around the use of the AX.25 protocol transmitted via FSK or AFSK at 300 to 9600 baud over FM or SSB. Most commonly, Bell 103 300Bd is used on HF over SSB and Bell 202 1200Bd has been used over VHF and UHF links. Links above 2400Bd require special hardware considerations and generally therefore aren’t as commonly used. Today we have software based modems to encode and decode enabling radically greater performance as well as the introduction of protocols such as [[https://web.archive.org/web/20160303180431/http://eludium.stensat.org/mcguire/projects/FX-25/Presentation_slides_02.pdf|FX.25]] and [[http://tarpn.net/t/il2p/il2p.html|IL2P]] which add a layer of FEC. The most popular use of AX.25 and packet radio today is APRS.
