- To: info-hams@ucsd.edu
-
- 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,

- 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

- happening so I'm trying to bring this discussion around to things that

- 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*

- 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.
-
- >3 - Would my best bet be to try to get a ham lisence? My only reason would
- > be for the phone service.
-
- 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.

- Actually I'm trying to say we need to set up the network

- I don't oppose people tapping into the contesting

- 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
