As far as traffic is concerned... Winlink now
carries upwards of 75% of all message traffic...
and it is incredibly efficient in doing so...
just imagine if we had to use the other less
efficient mechanisms to pass that traffic,
there would be no room on the bands for anything

OK, so Winlink conveys the equivalent of 5000 QSOs per day. Without
knowing or estimating the total number of amateur QSOs per day,
however, one cannot assess Winlink's spectrum efficiency relative to
other forms of QSO.
How many amateur operators are there worldwide?
What percentage of thes
Dave,
I said "as an example," however, you are correct about signal
detection. SCAMP is where we are going to deploy it, but it may also
be deployed in Pactor before it is all over. It is there, just not
used on the slave end. In my opinion, proper signal detection is
something that should b
Average 150,000 messages monthly or 282,000 minutes. Average time on
air 2.6 minutes.

Correction: I meant to say
"The hidden transmitter problem is well understood; protocols like
Pactor that lack busy detectors prevent station automation software
like Winlink from avoiding the inadvertent QRMing of ongoing QSOs."

Re: "From my perspective, as an example, opening a 3 KHz bandwidth
in a receiver for a 50 Hz signal, and then complaining about agacent
signal interference is not proper management, however, if the band
is segmented properly, that won't be an issue."
Steve, you seem to be implying that QRM to
Semi-automatic operation is permitted under the ARRL proposal -- and
would no longer be limited to specific sub-bands; it would only be
limited by signal bandwidth.

Those two numbers are apples and oranges Howard, as I'm sure you
know. To assess efficiency, one must compare Winlink's spectrum
consumption with the percentage of *all* amateur communication
conveyed by Winlink. Does Winlink handle 3.8% of all amateur
communication around the world? Highly u

I appreciate your comments, however, look at what is being said:

stations, Worldwide? Absurd..Simply a tactic to influence the ARRL

That is what worries me, as new modes come along. They may or may not be

here, but if other countries dont care, well , we still are using the
