S.A.R.T.G. Worldwide AMTOR Contest 1994 Results
-----------------------------------------------
Poor conditions spoiled this contest with only 27 contest logs and
3 check logs submitted. We will give major placegetters only, but
will include some comments as well.

---------------------- ----- ------
1. VP5JM 24150 points G0ARF 1485 JA3DLE/1 7350
2. G0ARF 21280 points DL8EDC 840 LZ1MC 6205
3. SM4CMG 16640 points (ony 2) OH2GI 4200
Comments
--------
G0ARF: It was very hard to find new contacts due to very poor
propagation, but we have to take it as it comes and make the most
of it. A lot of patience was required this year.
G4ZKJ: Pactor seems to be taking its toll of stations that were on
Amtor which is a pity.
GW4KHQ: Thanks for the opportunity to try something new. Cuagn.
VP5JM: The conditions for me were very poor -- a real shame -- I
enjoyed this contest last year but this year the results as you
can see were terrible.
LZ1MC: My first Amtor contest.
ZL2JON: I have only been operating for 17 months, and never have I
heard the band so quiet. It has not improved in the few weeks
since the contest either.

There are two parts to this question, 1) the presence of 1750Hz and
2) the suitability of a TH78A for use in Europe. As to whether 1750
is or is not present in the TH-78A, I suggest that you just press F-tone,
rotate the tuning control and see for yourself whether 1750 comes up
between 250.3, the highest PL and 67.0 the lowest.
There is another difference between the 78A and 78E and that is the key
layout. In the 78E the small button between PTT and MONI is the TONE, and
this allow access to tone burst even with the keypad closed or soft cover
on. In the TH-78A that button is CALL. This makes the 78A difficult to use
alone with a tone burst repeater. The solution is to get a speaker-mike
with function keys and then you can program a mike key to be TONE.

As things get cheaper, I only expect the computer components to be
noiser. An example is the lack of all metal cases on the market. Another
example is the number of motherboards for low-end systems that have little
ground plane. I've even seen some systems that don't have the the capability
to handle the ground current from the MB to the power supply!
If you want RF quite equipment, buy Tempest certified stuff. The
government has started to dump this stuff onto the second hand market.
You could buy a Tempest certified 286 or 386 for a few hundred dollars. Rip
the guts out and put in the machine you want (most of the ones I've seen
have been standard form factors).
I've even seen Tempest certified HP Laserjet IIs. They seem to want
to keep those and the monitors, but they still become available on occasion.
Another option is to buy industrial enclosers for all your PC
equipment. You could then shield all the components. Unfortunatly this stuff
is expensive due to the low demand. It also doesn't address the noise caused
by the keyboard. Power problems can be reduced by UPS, Isolation
transformers(also known as gravity sources), or even a good quality power
strip.
Good Luck and 73,

Subject: Ten Meter Sprint
To: info-hams@ucsd.edu
Greetings! To all of you who regularly work on ten meters, if the
propagation permits, you may hear a commotion on 28.450 MHz on Sunday
evening, 25 SEP, at 2000 EDST. The Thoroughbred DX Group of Lexington,
KY is sponsoring a ten meter sprint contest to introduce local hams to
the world of contesting.
The sprint will last for 2 hours. TDXG members will be contacting
newcomers to contesting with a desire to instill a love for same in
this group which ususally restricts their operating to VHF and UHF.
All of you are encouraged to contact us if you can hear us.
All participants will make an exchange of name, qth, signal report and
number. The number is derived as follows: TDXG members number is the
sum of states, continents, and CQ zones worked with a maximum number
of 97. Non-member general class and higher will use 100 while novices
and techs will use 200. As you can see, there will be a clear
advantage to the latter group.
In addition to creating a beginner's contest, we want to publicize our
use of 28.450 as a local calling and working frequency in central
Kentucky. Look for us whenever the band is open.
The TDXG meets on the second Thursday each month at Shoney's
Restaurant, New Circle Rd., NE in Lexington at 7 pm. Visitors are
always welcome.
73 es gud dxing,

Subject: Tesla coils
To: info-hams@ucsd.edu
O.K. O.K. O.K.. I know Tesla coils have little to do directly with amateur
radio but I couldn't find a newsgroup along the lines of rec.electronics to
post this. I never got into amateur radio (though I do work at a college
radio station) but you radio people always seemed to dig HIGH VOLTAGE!!
ZAP! Woah, feels good...
I've built several tesla coils in the past and am planning to build
one much larger than any I've previously built. I've got some ideas on how to
overcome some of the problems that I experienced in the past as well as a
few questions that require some explanation before I begin anew (sp?).
If anyone here has any experience with Tesla coils, knows anyone who
does, knows a good info source, or wishes to enlighten me as to the presence
of an electronics newsgroup (flame, flame...) -- please e-mail me. All help
is MUCH appreciated. Thanks...
