A if you read the editorial in this months QST you will find that the ARRL
is not in the coordnation business it only strongly supports coordination.
I really hate to take up for the ARRL but if they were in the coordinaton
business publishing a directory would be no more of a conflict of interest
than publishing the proceedings of a conference.

Here is one program made by John S. Watson 4/29/87.
It works ok, but I prefer SuperMorse on a PC...

Personally I think you'd be better off getting your fiancee to get an account

world, and using e-mail.

Hickory or pine? :-)
I was thinking of more than some crude relative indications, though
that's often useful. But how many amateurs have frequency counters
or spectrum analyzers that cover 10 GHz, or even bolometer power meters?
I do, but I don't know many others who do. How many are setup to measure
sidelobe responses for optimum feed positioning? Even I'm not set up to
do that properly and have to depend on manufacturer antenna range data.
How about simple deviation measurements on megabaud+ signals at 10 GHz?
If we're going to build a reliable national network, we can't be cavalier
about what frequencies we're using, or the power and performance of our
systems.
Note, I'm not interested *at all* in DXing or contesting. I consider both
to be the antithesis to the cooperative model needed for effective networking.
While I respect the technical prowess some contesters have shown, I don't
think they have the proper mindset for designing reliable data links. By
their nature, DXing and contesting are based on freak conditions, that
once in a decade band opening, that unusual ducting condition, etc. They
are not concerned about 7x24 fade margins, or 99% link reliability. Their
goal is to *compete* with their compatriots for score rather than to
cooperate day in and day out to maintain stable links. I'd be happier
working with repeater owners whose concern for proper reliable coverage
zones and 7x24 reliable service to the user community are primary.

Ok, if you're co-located with a Class B or C FM station, you're going
to have to deal with +50 dbW ERP signals, that's +80 dbm. Even if you get
70 db isolation, the signal at the diode is still +10 dbm. You've got
to do a lot better than that. A waveguide beyond cutoff is most effective
as a filter if it's length is 1/4-wave or greater at the frequency of
the interfereing source. (Attenuation doesn't get much better once you
pass the 1/4-wave depth.)

Yeah, though actually the tough problem is going to be with TV channel 11.
That's the low side image frequency of 219 MHz. That's solvable with high
side injection or an IF above 10.7 MHz. Note I've never said that we should
do it all on one band. Here in GA we're using a mixture of 222 MHz band and
430 MHz band systems in a checkerboard arrangement. I've got a bunch of
ex-GA Power data repeaters for the 902 MHz band as well. We should use what
works in a particular situation. My only point here has been that LOS 10 GHz
is unlikely to work in a *lot* of situations for various reasons that I've
already detailed in previous postings. Where it *does* work, then it could
be used if the microwave expertise is available to install and maintain
it. Otherwise we're going to have to look to other bands for solutions.
Look, we're finding that maintaining a 56 kb link is beyond the capabilities
of a major number of digital enthusiasts. And that's pretty simple stuff
that can be setup with just an ordinary station monitor and a scope. A
national network isn't going to be maintained by people with more general
knowledge or tools than that of the folks who maintain current digis and
voice repeaters. Most of them are totally lost when it comes to medium or
wideband data. It's *not* that hard, but we've got a major educational job
ahead of us to get these people up to speed on these techniques. And we've
got to offer packaged solutions that require a minimum of external test
equipment to get up, and to maintain.
The ideal piece of equipment will have indicators built in to indicate
that it's operating correctly with a clean on-frequency signal, with
proper modulation, and with undegraded receive sensitivity and selectivity.
Having a built in CNR meter and discriminator center meter are probably
mandatory, but that's not enough. You also need at minimum a reference
marker source of known frequency and strength to check transceiver frequency,
stability, and sensitivity. When you have two widely separated link ends,
you must be able to determine if the end you're at is operating correctly
or not, or if the problem is at the other end. You can't count on having
service personnel at both ends of a link simultaneously.
