Sheesh Karl,
As a "computer guy" trying to get reacquainted with radio after 25 years
in the digital (read virtual) world. I'm feeling a bit queasy back here
in analog world, having to be concerned with the temperature and color
of the plastic jacket. Ya know, a compendium of this stuff would be
just great for explaining those random problems computers experience
that we can't explain:
The color of the cable is wrong
The phase of the moon is not right
Gamma rays
etc.
I never cease to be amazed at the little things.
Thanks for your post

I'm GLAD that I don't have to invest in a $30.00 callbook (well, $60.00, for
both North America and DX). They're out of date before they're ever in your
hands! It's much cheaper for me to telnet to a more updated site than throw
away an obsolete $30.00 book. The telnet sites are also more detailed!

Subject: DJ-580 modifications
To: info-hams@ucsd.edu
I just purchased an Alinco DJ-580 which has already been modified
to recieve aircraft down to ca. 120 MHz on VHF and 810-900MHz on UHF. Are
there any other interesting mods that I might be able to do?
Also, there is a plug for "stereo out" (VHF left channel, UHF
right). When I plug this in, using a standard stereo jack, there is an
occasional squeeling noise. The mono jack does not do that. Suggestions?
Thanks in advance,
George

You will get more use out of the HTX-202 2m radio (144-148MHz). In most
cities, 2 meters is considerably more active than 70cm (440MHz, what the
HTX-404 covers). Here in the Richmond area, there are about 12 2m repeaters,
compared to 3 or 4 70cm machines. However, if you live in a larger city,
you'll find that the two bands are fairly even. That seems to be the case up
in Ohio.

Any amateur operator with a Technician Class license or higher can set up a
repeater. All you need is a tower site, a coordinated repeater pair (Where
this pair comes from depends on what part of the country you're in), and a
lot of equipment. Most importantly, it takes lots of money, which is why the
majority of repeaters are supported by clubs.

A good repeater would be the key to talking between Dayton and Toledo. Just
one repeater wouldn't do the trick, but there is an extensive netowrk of
repeaters throughout the state where you could talk between the two cities.
Hope this helps!

This is an NTIA study (see other postings). The comment period
runs through May. I don't know when the FCC gets involved, but I would
assume they have to be involved at some point.
We should indeed mobilize to prevent industry use on this band.
A key part of this would be to present the history of sharing with
industry on 900 MHz, which has resulted in a near exclusion of Amateur
traffic from the band.
I would think that the performance of ARRL is going to be critical on this
one (please everybody hold the pessimism postings - I know, but they are all
we have). Would anyone from ARRL like to post on this?
Thanks

Tune up the radio in the conventional manner.
Drill a 1/2" hole in the side of the radio just above the first IF stage
coil; install a bulkhead BNC female connector. Chop the receive antenna
lead off the antenna relay and use this connector to bring it out of the
radio to your duplexer.
Clip out diodes D1, D2, and D403.
Add a control system. All the connections you need are on the control
connector on the front of the radio.
Voila' - it's a repeater.

Thomas -- The Y32JK call is not listed (at least so far as I can find). In
fact, none of the old GDR calls seem to be listed in this year's edition.
The address for the DL5ATP call is listed as Thomas Planke, Postfach 113,

And you believe it is OK to call an individual a liar on rec.radio.amateur.
misc???? This all started when Jeff posted his two-year old, archived flame
against Ramsey. I didn't object to his or anybody else's slam of Ramsey
products. I objected to his emotional outburst and airing his private dirty
laundry agenda (for the Nth time)on a technical news group.

Yup, someone bad-mouthing a bad-mouther for bad-mouthing a bad-mouther
seems ironic to me and most of my Internet friends. Again, I'm truly
sorry if I offended an innocent party.

To: info-hams@ucsd.edu
The ARRL is making empty threats. The data in the repeapter directory is
no more propiratary than the information in the phone book. In fact Wayne
Green was putting out a directory before the ARRL and they stole it from
him according to Wayne. It's a shame that the ARRL (I am a member) can
think just because they have fuzzy balls they can threaten person with no
means of hiring council. Fortunatly there is an answere in the American
Civil Liberties Union. Give them a ring or if you don't want too I will
and get their oppinion. The ACLU scares the shit of anybody they bring
their guns to bare on.

Subject: Repeaters
To: info-hams@ucsd.edu
>- Can repeaters in fact be used to place local telephone calls? If so,
> is there a charge for this service? Is it limited?
Yes. Some repeaters have autopatch capability. Most of those are
club-sponsored repeaters which require you to support the club for autopatch
access. Of course, business calls are prohibited, and you must keep in mind
that everyone is listening to your call! The club I'm with here in Richmond
limits your call to 3 minutes, and aside from club dues, local calls are no
extra charge. For those of us who are a long-distance call between the
repeater and our homes, they cover $1.00 of the long-distance charges. Check
with some of your local radio clubs to find out what their policies are.
>- What are the legal restrictions on amateur radio traffic? Are data
> connections allowed?
Data conections are allowed. It's called packet radio. Some packet links are
even connected to the Internet. Listen around 145.000 to 145.100MHz. You may
hear an occasional packet burst down there.
>- What baud rate could I reliably connect at through a radio link?
>
On the 2m band, most links are 1200 baud, which is sufficient for local
communication. Many sites that forward large amounts of traffic are
experimenting with 9600 baud connections.
Hope this helps!
