The module has exhibited instability and failure when exposed to low temperatures. It is recommended to reboot the module every 20 telemetry transmissions.| Not suitable for long duration flights without lots of insulation.

-Note "Poor" stability means unless well insulated the frequency will drift noticeably.+Notes :\\  
 +"Poor" stability means unless well insulated the frequency will drift noticeably. \\   
 +"Simple" Complexity means suitable for beginners. \\ 
 +All modules support RTTY, analogue FM ones support APRS via external DAC
