Well with the old SkipNet, the ARRL submitted/requested an STA and one was
granted for one frequency on 20M, one on 40M and I think one on 80M. Which
didn't keep someone not listed in the STA from using the frequency but rather
making all the SkipNet stations stay on the "assigned" frequencies.

They should start using MT-63 as all PC Sound Device Modem based

As Walt states, there is a need of a pool of reserved frequencies for
automatic or semiautomatic operation, in order to
avoid clashing with others.
I have been a packet sysop since 1992, and it was the way it operated.
Noone who is not a member of the forwarding net is welcome, even in
packet,
I am gearing up for sending images via MFSK upon 12/15/06. What pixel
sizes are recommended for MFSK images? Been so many years since I did
it I no longer remember.

Walt,
If neither A nor B can hear either C or D, then generally speaking that
also means that C and D cannot hear A or B and there would be no
interference problem. There may be rare cases of one way skip, but
nothing can do anything about that.
The hidden transmitter effect occurs when you ha
nd go play on a 2M repeater. Hi Hi.

assuming that C is hearing either A or B or even both? In this case, if A
and B were already in QSO, then C and D should QSY to st

If A and B can hear each other but can't hear C or D then if A or B transmits
and C is receiving D, then C is QRMed and can't copy D.
This is something that happens quite often on HF and I don't think that any
amount of coding willremedy this problem.

The "hidden transmitter" on any band and especially HF is always going to be a
problem. It is not only a problem for us, but also in the commercial and
military communications world.
As hard as we try, as operators and using smart software, we will not overcome
the problem.
We then are left w

No QRL... no nothing.
Maybe I should just publicly post my operating schedule
