To: [e-mail]

Too bad... I dealt with them about ten years ago, and they were tripping over
themselves to give me excellent service. They spent a lot of time describing
products to me, and then when I ordered the radio, decided I had enough fun
(in a couple of weeks) and sent it back, they gave me my money back pronto.
I liked them.

It seems to me the FBI and FCC are trying to drive scanner manufacturers out of
business by continually forcing them to redesign the circuitry. These laws
aren't enforceable anyway unless you use the info in such a way that it can be
proven you listened, which in itself is illegal.

Subject: IRS 501(c) tax-exempt status for our club - How?
To: [e-mail]

Hello - I was wondering if anyone was a member of a club that has Federal
501(c) tax-exempt status?  We would like to know how to do so ourselves.

We are Humboldt Amateur Radio Club, Inc., and are a state non-profit
organization.  We have three chapters, each independantly governed
and maintaining their own identity.  We have been working with a local
attorney who took our three page Constitution and By-Laws and turned it
into twelve pages of legalese and left out many important parts, such as
the identification of our chapters.

There has to be a relatively pain-free way to do this.  Does anyone
have any advice on how to proceed from here?

                                Thanks in Advance,

This means "I'm tired of listening to you, windbag. I'm going somewhere
else." (On rare ocasions that somewhere else may be outside the car, but
not usually.)

>very good
>fine business

These are just null noises emitted instead of, or in addition to, "Uhhh"
and Ahhh" as space fillers for dead air. In some rare instances, they
may actually mean "OK" or "I heard you", but the ham couldn't bring himself
to use plain English. Their presence almost always means that no real
conversation is occurring.

Not quite Al, you can get lower power HF slugs but they have severly restricted
bandwidth, close coupling is required and the response suffers.

A good side of this is if you get a 1KW slug for VHF it often covers more than the
frequency written on it. If you get a 1kW 200-500 MHz slug, it does a reasonable
job on 144 MHz (you can always calibrate it against a known meter calibration on
144 MHz, and not too bad on 23 cms.

I have a 500W 50-125 MHz slug that is fine on 144 MHz. The error is less than I can
measure against my genuine 250W 144 MHz slug.

I also use a 200-500 MHz 5W slug. It is fine on 432 MHz but also quite useful on
144 MHz. It is way out of calibration but it is still directional.

The onl HF slug I have is 500W 2-30 MHz. I think that is the lowest power available
to cover the whole band

If you can show how to setup and *maintain* 7x24 megabaud+ links to all
areas of the US, I'm all for it. I don't see a chance in hell of that
happening so I'm trying to bring this discussion around to things that
are within the realm of the *possible*. 56 kb beyond LOS links look
possible to me, many thousands of 10 GHz megabaud+ LOS sites do not.
It's not microwave *technology* that's the problem, it's the *sites*
and the people to maintain them that are the problem. Amateurs don't
have enough of either to establish a *national* microwave network, and
little or no hope of getting them. (Local or regional megabaud+ links
may be possible in certain areas, and I encourage that, but it just
isn't going to happen nationwide unless we suddenly get 20 million new
hams with optimum geographic dispersion.)

We're dealing with a very sparse matrix here. You don't seem to understand
that as you sit in a dense metroplex with hams on nearly every block. The
rest of the country just isn't like that. *Most* of our links are 60-80 miles
long, over unfavorable terrain, to sites we can *get*. Nearly *none* of them
are LOS. We *depend* on the beyond LOS propagation available most easily at
lower frequencies to maintain those links. (If we could muster the power to
do microwave forward scatter, that would be different, but there just aren't
enough surplus TWTs out there to do the job, and site managers frown on 32 ft
dishes on their towers. We *can't* depend on inversions and ducts, they just
aren't reliable enough.)

Yes it's possible, and no the party on the phone isn't permitted to turn
around the link (in the amateur service). A licensed individual has to do
that, and it's normally done by the mobile operator dropping his carrier.
IE you unkey the mic and the patch begins transmitting the phone line audio.
When you key again, the patch starts feeding your audio to the phone line.
Hence *half* duplex.

Note a repeater can do this easily because it's listening on a different
frequency than that on which it's transmitting. For a *simpatch*, which
isn't a repeater, it's a bit more complex. The patch *samples* the frequency
at short intervals (say 1/10th second every second) by dropping it's carrier
and listening for yours. If it hears your carrier, it turns around, if not
it goes back to transmitting phone audio. The short pops aren't too annoying.

>2 - Is there a charge for using ham repeaters.

Technically no. Amateurs aren't allowed to charge for the use of their
stations. However, repeater owners have the right to limit access to
their equipment, and one way they do that is to require operators to
be members of their "club". There may be annual dues associated with
the club.

No. It's expressly forbidden for amateurs to use patches solely to
avoid telco charges. If you want mobile phone, get a mobile phone.
Patching is allowed in the amateur service only for experimental
purposes, and for public service and emergency uses. They are not
to be treated as alternatives to cellular, IMTS, or other common
carrier systems. (Casual patches should be viewed as ways of
*testing* the experimental or emergency system.) This is covered
in Article 32 of the international regulations. (The FCC allows
quite a bit more latitude for *domestic uses only* than what the
international regulations require, but that doesn't mean there's
a blank check to abuse the amateur system as a way of avoiding
using the public telecommunications systems.)

>4 - Could it be done with a CB?  Would it be legal?  What is the range?

I've heard simpatches being used on CB (Hell, I've heard all sorts of
things on CB). I'm not sure whether such an interconnect is legal in
the CB service. Part 95 doesn't say, but it may fall under the same
common carrier restrictions as other telco bypass schemes. Simpatches
are legal in certain *commercially* licensed services. That would be
your best course if you *must* interconnect to the telco system via
your home line. Otherwise, an IMTS or cellular phone is your best
alternative.

To: [e-mail]

In the last QST, they reviewed 4 different dual-band HTs. The question I
have, is what is their extended TX / RX frequency range when modified?

For example, I've heard a rumor that the TH-78A can transmit AM down in
the aircraft band. I don't believe it, nor would I ever want to transmit
down there!

I've also heard that most receive well into the 800 MHZ range.

Can anyone enlighten me?

Ah, but which version of STSPLUS is it ?  The damned thing gets updated
two or three times a year, or so it seems. The version numbering is pretty
unusual as well. For what it's worth, the latest I've seen is 9353, which
if I recall the method makes it the last week in '93. 9333 was the last
*major* upgrade.

Actually I'm trying to say we need to set up the network
the *right* way with people who will *keep* the network
operational as a service provider. That's a different
mentality than that normally found among DXers and
contesters. (Not that there aren't some from those groups
who *also* have the service mentality, just that it isn't
a normal part of DXing or contesting.)

In reading the articles on 10 GHz operating in the current
QST, one wouldn't get the impression of *reliable* links
with 50 db fade margins that work reliably 7x24 year after
year. *That's* the kind of links a digital network must
have.

I don't oppose people tapping into the contesting
domain for some experience and training on 10 GHz
equipment. But I must caution them that the sort
of training that they'll get isn't directly transferable
to setting up and maintaining *reliable* data trunks.
I got my own training and experience in the commercial
world setting up and maintaining intercity relay sites.
That's the sort of carefully engineered systems we have
to have for a national data network.

Looking at the cummulative results table in QST, I'd
say that such equipment is spread mighty thin for a
national network.

Ah yes, DX Packetcluster. "Hey George, the link's flaky."
"Well put up stacked beams and pile on the kilowatts,
to hell with the other digital users, the DX spots
have to get through."  (I've actually heard exchanges
like that. The lack of cooperation between the Packetcluster
operators and the rest of the digital community is somewhat
legendary. It's that Type A DXer mentality.)
