I'm an odd ham in that I smile with amusement when amateur radio groups rush to "defend" frequencies and worry about some non-hams getting "our" frequencies. I happen to think we have more than we need and can easily give some away. With that in mind , here are some freqs for PACTOR and ALE stations to inhabit. They can then do their unintended "thing" til their heart's content.
1808 to 1815 3577 to 3584 The entire 60M band (a good band, and we don't need it for anything else) 14.105 to 14.110 24.890 to 24 .925 That's it, nothing else. The above frequency allocations would be sufficient for PACTOR BBS, automatic ALE soundings , ALE SMS messaging, and PSK MAil servers . ALE, PACTOR and others could use other allocated digital sub-bands but not unattended. No busy detection required (optional) in the" automatic zones" , mailbox operators would work out their voluntary QRV schedules via their "Frequency Coordination Council" . The above frequency ranges would give PLENTY of room for message traffic and emergency communication drills. Yes, no 40, 30, 17,15,10, freqs...simply not enough demand and no real propagational needs. OK, now off to have lunch with the FCC chairman, see if can implement in the USA by next Friday. Rest of the world, they'll just have to adjust :>) Andy k3UK
