And another point worth emphasizing is now that MultiPSK's RS ID detection can be extended throughout a 44KHz bandwidth using its SdR interface, it should be possible to initiate an ALE400 FAE ARQ connection to a friend using their SELCAL which will be detected by them automatically anywhere say in the entire 20m digital portion of the band if they have centered their SdR frequency to 14.091MHz (14.070-14.112 range).
No need to scan on discrete frequencies, just monitor the whole digital band at once. To me, this has obvious EMCOMM possibilities. 73 Sholto K7TMG Tony wrote: > All, > > Had a chance to see ALE-400 in action for the first time thanks to K7TMG.
