Andy, The FAE modes are not really all that new. I had promoted it back in July 2007 on one of the eham forums when I asked if other public service operators planned to use this protocol. There have been very few hams interested in such a mode.
My personal preference is to refer to it as FAE, unless it is actually used for Automatic Link Establishment. This is partially to avoid the confusion with ALE operation, and to defuse the hostility that most hams have toward ALE operation. Of course, it theoretically could be used in an ALE system, but I don't see this happening all that much for most ham purposes since what we mostly do is the opposite of ALE. As we gain experience, we know which bands are open (or can quickly check) and then cast out our RF or answer some other stations RF on shared frequencies with varying bandwidths. For public service use we are likely to set up a specific frequency of operation, but having several frequencies on different bands is always possible. I heard Tony, K2MO on this evening working a station near 14.074 using Olivia, but then he switched to FAE40 and called CQ. We were not able to link as the band appeared to be dropping out by then. I called him back and also called CQ to no avail. One other important, and convenient thing about these modes is that the convention was retained to always center on 1625 Hz audio frequency, so your dial frequency is the frequency of operation. 73, Rick, KV9U Andy obrien wrote: > First, is it really ALE as used currently?
