I posted a request for the AMSAT BBS number. Some nice gentleman
sent me a message saying it was 303-447-3003. I called that
number, and it is disconnected. Anybody else have their number?

Don't think this is League policy; the ASM decided that he knew
what was legal and positioned himself as a vigilante.

I beg to differ, Bob. First, I don't think it's illegal to own
a radio that can transmit outside of whatever frequencies I'm licensed
for. If it is, I'm in big trouble with my TS-930S because that rice-box
will transmit above the ham phone bands just fine as it came from the factory.
I have modified my TH-75 for out of band transmit, not for the purpose of
transmitting out of band, but so I could expand the recieve coverage. It
so happens that in doing so, the transmit capability was also opened up.
In the case of 70 cm, I can now transmit anywhere in the 70 cm band, not
just in the repeater portion meaning I can now monitor packet activity!
If it were truly illegal to *own* equipment that could transmit outside of
one's licensed capability, most hams would be in deep yogurt.
We can modify our radios in any way we wish, we just can't transmit
outside of our allocation. There are lots of valid reasons to do this.
CB'ers can *own* ham equipment if they wish, but they can't legally transmit
with it... Unfortunately, the FCC doesn't seem terribly interested in
enforcing those rules right now, but that's another discussion :-)
To those diligent souls who uncover all these mods, thanks very much!
Keep up the good work! Along those lines, anybody know how to turn a
Kenwood TH-75 into a cross-band repeater?
Merry Christmas!
Kim Elmore, N5OP

I recently posted a mod for Icom IC-2GAT, and mentioned that a friend
had verified it.
The young ham who modified his 2GAT got his license only 3 months ago,
and it is his first rig. He was very apprehensive about opening the
radio and soldering an extra diode among the tiny surface-mount
components inside. His delight upon success was wonderful to see!
Graduation from appliance-operator to hacker is a significant rite of
passage for any ham, no matter how simple the actual operation. Thus
reinforced, he will advance to more complex hardware projects. The
complexity of modern commercially-made ham gear can intimidate people
from one of ham radio's major purposes and delights, experimentation.
I'm glad that many modern rigs have simple ways to make profound
modifications.

Message-ID: <1186@east.East.Sun.COM>
Tried to mail, but bounced:
I have the ICOM IC-32AT, I like it alot, typical bullet-proof ICOM
construction. Easy to mode for extended rcv in both vhf and uhf, also
cross band rptr mod is easy. It's also the only one to put out 5 watts
with the included (BP-70) battery. Only two negatives, it's on the heavy
side (that BP-70 is fairly heavy) and you cannot listen to both vhf and
uhf at the same time (no balance control). It will listen to one and
monitor the other and switch based on the priority you set though. I hear the
Yeasu FT470 has problems, I'd stay away. A friend bought the Kenwood TH-75
at the same time I got the ICOM and he seems happy with it, it's a lttle
lighter, but only puts out 2.5 watts on high power. Either the ICOM or
the Kenwood are good choices in my opinion. I'm sure there are some
Yeasu owner's that will swear it's a good rig also :-), Caveat Emptor!

Message-ID: <2702@radio.oakhill.UUCP>
Since there is a commercial meteor scatter system in place (monitoring
snowfall?) it would be nice to tune in to the master station's beacon
frequency and "listen" for meteors. What frequencies in the US are
currently in use as the master station for meteor communication? Bob
Parnass... is there any way you can look this up in your database? The name
of the company was Meteor Communications Corp of Kent, Wash. I think.
Thanks in advance,
Charlie Thompson

With regard to the above, *please* don't write to NOAA requesting
information unless you are actually building a satellite ground station!
NOAA NESDIS is not that well-funded, as you can tell if you've ever seen
the diagrams/descriptions of their equipment, and it costs them a good
bit to send out the literature. It's currently hard to get them to
reply to requests for information (I have been waiting several months
already to receive information on the TIROS DSB Beacon content),
apparently because they just don't have that many people available to do
that sort of thing.
The information provided in their literature is primarily information
about how to calculate the orbits of the satellites, etc. A lot of it
is out of date, since it tells how to manually calculate the orbits
using maps and charts, whereas there is public-domain software available
(such as ORBIT23 on SIMTEL20) which does all that for you automatically.
Much more useful information for getting started is found in the ARRL
"Satellite Experimenter's Handbook," which tells how to build the
required antennas, gives information on properties of the signal, etc.,
and in Larry Horn's "Communications Satellites" book from Grove
Enterprises, which contains the same information as in the NOAA
literature (and in more detail, for the most part). The Grove book also
tells about the Soviet satellites, which aren't mentioned in the NOAA
literature. The commercially-available (low-cost) packages people have
mentioned, such as Elmer Schwittek's package, also contain this
information. NOAA is currently very helpful with people building ground
stations, but this is largely due to the efforts of Earl Popham, who was
personally interested in helping radio amateurs, and who recently
retired after many years with NOAA.

Subject: rec.scanners
Bob, KA1GT, suggests that the voluminous scanner information
currently occupying the net should be distributed elsewhere.
I most firmly agree. This is rec.Ham radio, after all.
Scanner fans have every right to air their views, discuss
whatever they want to, distribute frequencies, etc. But
if this net is for ham radio, that's what its postings should
contain. I just don't have any interest in that topic, and
I doubt that most of the amateur radio operator readers of the
net have much interest in it, either.
This point was at the root of my "who cares?" mini-flame last
week. It was amusing to see that all the responses in support
came via direct e-mail whereas all but one of the hate-flames
were posted globally. No doubt Bob's (and this) posting will
generate the same fiery response from our scanner friends.
Go ahead, make my day.
