Thanks Larry for the informative update on cell system operations.

You also did a good job in this thread of explaining the shift of HF
guard frequencies from duplex to simplex. I suspect there could be
some confusion with operators of marine transceivers that may have
difficult to override default duplex operation. The new guard
frequencies were originally set up by IMO to be duplex, and making new
policy is easier than changing default settings on radios.

I think in the near future the HF marine bands will just be dead, except
maybe for the Coasties who survive the next round of budget cuts from
bankrupt governments....like ours.

The commercial traffic, except for a few third world shipping, is all on
Marisat or the other global LEO satellite birds. Simply put, it just works
better, especially in really lousy weather when HF is so damned noisy you
can't even hear yourself....

I think the ham bands are going to get BIGGER as commercial and government
interests move off HF to better classes of services. Noone wants more HF
spectrum any more.
