Subject: Clubs and Repeaters
To: info-hams@ucsd.edu
Our local club, of which I am an officer, wants to install, own, and
operate a repeater. The equipment, site, etc. seem to be the easy
part (even the coordination :-). My question is this: What
organizational structure do other clubs use to operate repeaters?
Not all members of the club are going to participate in the repeater
funding or operation so there is likely to be two levels of dues and
participation. What kind of legal agreements (if any) are required
between the club and the trustee? Are there any legal requirements
for the club regarding non-profit status (it will have assets and
raise funds to support the repeater)? Should the club incorporate?
Being neophites at this, I would like to hear what other
clubs/organizations have done and how they have structured
themselves to deal with this.
Thanks in advance for your constructive comments.

I sent cash(US$) via air mail and got it. It was a few years ago.
It really works well. Several months later, I tried again for a

The Hamblaster Update
The Hamblaster will be introduced at this hamfest.
JANUARY 1994
Jan 30, Sunday: Odeum, Villa Park, IL - Wheaton Commun-
ity Radio Amateurs hamfest. Odeum Expo Center. 8 AM -
3 PM. Tickets $6 advance, $8 at the door. VEC test-
ing. All flea market tables reserved. To reserve a
table, call (708)231-2428.
Over the past several months I posted updates about a
DSP "The Hamblaster" that Will Torgrim (N9PEA) and myself
are developing.
We are focusing our efforts on a packet modem that allows
the user to improve H.F. reception by interfacing the Ham-
blaster (a PC compatable DSP sound board) to a transceiver
and a packet or all mode TNC. Modems/filters for RTTY,
Packtor, Amtor are also under developement and are compatable
with the same control panal software.
Here are the latest developements
1) We do Windows! There's a receive/demodulator
control panal that allows me to control the FSK demo-
dulator's filter center frequency using a mouse driven
slidebar. There's also an on screen tuning indicator that
mirrors the tuning slidebar. You tune the filter by moving
the mouse cursor over the filter tune slide bar button and
when you press the left mouse button the slide bar button
moves.
2) An option allows me to lock the tuning indicator to the
"Filter Tune" slide bar. The Hamblaster sends frequency in-
formation, that it hears at the output of the first filter,
to the PC via the PC's I/O epansion port. Even in noisy
conditions it can count the center frequency of an FSK signal.
The tuning indicator does jump around in noisy conditions
3) A new Windows control panel provides an on screen digital
storage oscilloscope. By pressing the "SNAP SHOT" button,
you can capture 4 signals and display the traces in a graphics
window. The traces can be resized or you can move the window
left or right. About 100 ms per trace is aquired.
You can select or attach the 4 traces to any of the signals that
are displayed on a block diagram in the o-scope control panal.
The Hamblaster captures the signals and stores them in it's own
memory. Then the PC gets the data from the Hamblaster via the
PC I/O port and stores it in the PC memory. The software
displays the aquisition by getting the data from the PC RAM.
The process takes about 2 to 3 seconds (the DOS version takes
about 1/2 the time to execute).
4) Using Windows multitasking, you can run the Hamblaster software
and your favorate a packet program (like PC Packratt). I was even
able to run two instances of the same Hamblaster software. Both
control panals displayed the tune bar and responded it real time.
I also got two o-scope aquisitions.
1-3-94
5) We now have FFT analysis software built into the o-scope control
panel. When you click on the "Freq" button the audio spectrum is
displayed. You can move the mouse cursor over the display and
where ever it is positioned, the frequency is displayed in the
status window. When you click the mouse the modem filters jump
to the frequency. This feature provides a simple tuning aid.
Another button allows you to convert all 4 traces (mentioned in
paragraph 3) to spectral displays. You can, for example, analyze
the frequency at the input signal, the modem prefilter and the
mark filter output. Based on the FFT, a second button allows
you to modify the filter tune limits by clicking on min-max
limits that you select.
I have to admit, After I debugged the FFT software and I getting
the control panel working to my satifaction, I got hooked on the
operation of the Hamblaster system. I spent hours tuning the 40
and 20 meter bands, displaying the FFT and copying CW/RTTY signals
through the Hamblaster filters. The FFT really simplifies the
tuning process.
Ongoing developments;
1 Post detection carrier detect.
2 HDL protocol decoding
3 Morse code detection/regeneration
4 Adaptive voice filter.
7 DTMF & PL tone detection.

No words of wisdom re: starting a club - I was lucky enough to join one
that is over 40 years old. :)

Just go on! I am a member of a club station here on the university, in a
matter of fact i am the vice-president of the club. It's very nice to see
people that were never interested in the radio hobby, just having fun with
packet or so.
Good Luck with your club,

rec.radio.amateur.policy has served as our de-facto advocacy newsgroup,
as most of the advocacy wars seem to revolve around FCC regulations,
no-code licenses, content and administration of VE exams, etc. Excerpted
from the Guide to the Personal Radio Newsgroups, posted monthly:
"The first reorganization added two groups to the list, one of which is
rec.radio.amateur.policy. This group was created as a place for all the
discussions that seem to drag on interminably about the many rules,
regulations, legalities, and policies that surround amateur radio, both
existing and proposed. Recent changes to the Amateur Radio Rules (FCC
Part 97) have finally laid to rest the Great Usenet Pizza Autopatch Debate
as well as complaints about now-preempted local scanner laws hostile to
amateurs, but plenty of discussion about what a bunch of rotten no-goodniks
the local frequency coordinating body is, as well as the neverending no-code
debate, may still be found here."
If people aren't using the newsgroup (although many clearly are, if recent
traffic on it is any indication), it is for reasons that won't be
eliminated by the creation of yet another rec.radio.amateur.* newsgroup.
There was also a recent reorganization of the newsgroups (mid-'93), so
people are likely to be burned out on the idea of creating more
newsgroups. If you are interested in discussing this further off-line
with about two-dozen or so newsgroup veterans and FAQ maintainers, there
is an excellent forum for this purpose, namely the rec.radio.amateur.*
Working Group mailing list. If you'd like to subscribe, send E-mail to

I'm working on some identification badges for our radio club's

people have done (or found) that might be suitable.
Ideally, something that can be imported into macpaint would be best,

Subject: Peltier Diodes - HELP!!!
To: info-hams@ucsd.edu
Greetings and Happy New Year!
I am interested in obtaining information about thermoelectric
devices called Peltier Diodes (junctions?). My extremely limited
understanding of these devices is that at low voltage DC they act as
unidirectional heat pumps, and have been used in electric cooler
units with suitable heat sinks and "cold" sinks on the heat energy
input side. Since I am NOT an electrical engineer (a
botanist/professor actually) I'd appreciate any information the
engineers among you might have as to how these devices work
(practically, not theoretically!), how they are rated, and if
possible, how to use them in constructing cooler units. These might
be useful for improving efficiency of power supply heat sinks?? but
honestly, my ulterior motive is in the construction of a
cool-chamber in which to store my homebrew beers!! As a ham with a
very small modicum of electronics background (pretty damn small!),
I've been asked by some fellow homebrewers to investigate these
beasts, and try to prototype some "homebrew" coolers for our
homebrews (pretty neat, eh?).
If any of you have information about these Peltier devices,
application notes,m thermal ratings, recommendations for
installation/increasing efficiency, etc. I'd be (actually WE'D be)
very appreciative to learn about these, or at least sources where we
could get more information. Thanks in advance for your help....

I disagree that the kits are cheaper. I bought a Ramsey SCA decoder for
$25 that did NOT work in kit form. I finally gave up and bought an SCA from
another company for $20 ASSEMBLED TESTED and it WORKS!!!! so much for

When I lloked at the SCA design they had I found that the frequency
response was down 43 DB at 67Khz which is where the SCA info is at.
others have found some alternate CAP values to make it work but why should
users have to design RAMSEY products for them??

It doesn't have to...the eight inches specification relates to the
proximity of the (shielded) antenna cable to the ECU. A transmitting
antenna could be much further than 8 inches away and still induce large
RF currents in the ECU leads. However, with the ECU being located inside
the car body, the ECU leads should be shielded against outside sources
of EM fields.
