* VE3ONT EME CONTEST SKED *
===========================
The Toronto VHF Society, VE3ONT, will participate in this year's ARRL EME
Contest using the Institute for Space and Terrestrial Science's 46m (150')
Algonquin Park dish (located at grid square FN05xw). This year's operation
will provide an increased opportunity to work 144 MHz stations.
UTC Date VE3ONT TX Freq Listening Range Approx. Times
29-Oct-94 432.050 MHz 432.050 - 432.060 MHz 0645 - 1815 UTC
30-Oct-94 1296.050 MHz 1296.050 - 1296.060 MHz 0754 - 1844 UTC
26-Nov-94 144.100 MHz 144.100 - 144.110 MHz 0538 - 1645 UTC
27-Nov-94 144.100 MHz 144.100 - 144.110 MHz 0646 - 1713 UTC
Because the Algonquin dish has a 9 degree lower elevation limit, stations
with horizon fixed antennas in eastern North America will have a limited
chance to work VE3ONT. The following operating hints will improve your
chance of making a QSO:
- As in 1993, VE3ONT will work "split" frequency. Do not call on VE3ONT's
TX frequency. Pick a random frequency in the listening range. Use the
full range. VE3ONT will be looking for stations in the clear.
- VE3ONT will use circular polarization on all bands. You may use linear or
circular polarization to make a contact with VE3ONT. If circular, use
RHCP on TX and RX for the 144 and 432 MHz bands. On 1296 MHz, they will
have switchable sense so you may use either the satellite or EME
polarization convention.
- Conditions permitting, VE3ONT may start each operating period on SSB to
work strong stations as quickly as possible. Please do not call again for
a second contact on CW. Conversely, if you make a contact on CW, please
do not call again for a SSB QSO.
- All contacts will be "random" with no schedules or sequencing. Please be
patient. VE3ONT experienced a great deal of QRM during last year's event.
Low power and OSCAR class stations are encouraged to make an EME contact
with VE3ONT. 100 watts delivered to a single long yagi should be sufficient
on the 144 and 432 MHz bands. On 1296 MHz, stations were worked with as
little as 10 watts and a 2m (6') dish in 1993.
Be advised that use of the dish at the Algonquin Space Complex is always
subject to last minute preemption for non-Amateur purposes.
QSLs with an SAE should be directed to Dennis Mungham VE3ASO, RR 3,
Mountain, Ontario, Canada, K0E1S0. Reception reports are also welcome.
Send your log to the ARRL.
For further information, contact Peter Shilton VE3VD, (905) 774-8766.
The latest developments will be provided at the Central States VHF
Conference July 29-30, Memphis, TN, and the International EME Conference,
Gottskars, Sweden, August 26-28.

* NEW SPACE ORGANIZATION *
==========================
A group of space science educators involved in the use of classroom
and school space simulators (including permanent, semi-permanent,
and temporary simulators) met at University School in Shaker
Heights, Ohio (a suburb of Cleveland) during July of 1994 for the
purpose of establishing a national organization.
The purposes of the organization are:
1. To facilitate the exchange of ideas, information, and technical
enhancements among simulator using educators.
2. To assist teachers interested in developing space simulators.
3. To provide consultation services to teachers and schools
regarding the use of space simulators in space science education.
4. To encourage the use of the information superhighway as a tool
for enhancing space science simulations.
5. To provide assistance regarding sources of free or low cost
resources and materials from the aerospace community, government
organizations, and information providers.
6. To advance the use of simulation as an educational technique in
all areas of education.
Membership in The National Association of Space Simulating
Educators is open to anyone interested in education. The
organization's focus is school educators at all levels from pre-K
through college.
For a free informational pamphlet, write The National Association
of Space Simulating Educators, attn. Robert E. Morgan, University
School, 20701 Brantley Rd., Shaker Heights, Ohio 44122 or send
electronic mail requesting the pamphlet to: nasse@shadowso.com.

Be patient. 6 m is quiet right now but recent past gave me over
100 new grid squares. If you are looking for a busy band, 6 isn't
it. It is patiently waiting and watching and listening for the
openings to occur.
When they do (tropo, Es, Aroura) all hell will break loose. It
will give you a contest adrenalin rush!
I'm running a FT736r (satellite rig) with a 6m module, Mirage
150w brick and a 5el CCraft at 30ft. When the band is open, or an
Aroural opening hits be prepared for a wild carpet ride.

Congratulations Dan! A 1/4-wave groundplane is traditional, but it
offers some problems for electrical safety, and for performance.
A better choice would be a J-pole made from copper plumbing fittings
and pipe. There have been several articles in the ham press, and
here, on how to build this simple antenna. It has the advantage
of DC continuity, which simplifies mounting and surge suppression,
and more gain toward the horizon than a 1/4-wave antenna.
The National Electrical Code says an antenna mast must be grounded
with a minimum #8 solid wire going in as straight a line as possible
from the mast to a ground connection. The ground should be, at minimum,
an 8 foot driven rod. There should be no sharp bends in the ground lead
which can present extra impedance to the flow of a lightning induced
surge.
If you look back through the archives, you'll find more detailed and
elaborate recomendations for station grounding and protection than
those set as minimums in the NEC. If you suspect your antenna will
be a target for lightning, you should consider taking those additional
steps.
You can use a chimney mount, like the one Radio Shack sells, to support
a piece of TV mast, also from Radio Shack, that will in turn have the
antenna clamped to it's top end. If you build the J-pole, automotive
stainless steel hose clamps can hold the antenna to the mast. If you
opt for a purchased 1/4-wave groundplane, mounting hardware should be
furnished with it. Use good quality coax, avoid Radio Shack for this.
Belden 9913 has the lowest loss, but RG-213 is also good. Weatherproof
your connections carefully. A proper gas discharge surge suppressor,
such as those sold by Polyphaser, should be included in the coax where
it enters the house. The suppressor should be connected to the same
ground used for the antenna mast, using the same kind of wiring technique.
Don't daisy chain ground connections, run a separate wire to the ground
rod.
Have fun!

Actually only the very cheapest (analog) radios are like that. They
cover only the bands used by shortwave broadcasting. The fewer
frequencies they cover, the more they can spread them out on the
dial, and that makes finding stations easier on an analog set.
They cover broadcast bands, not WWV, because WWV is just to boring
to sell :-).
But you don't want an analog radio anyway. You're going for an
occultation: you only get one chance. Shortwave propagation and
Murphy's law being what they are, you'll have WWV tuned in at 10
MHz, and it will fade right out 5 minutes before immersion. With
an analog radio you'll be frantically fishing for an alternate
frequency when you ought to be guiding your telescope.
Go to Radio Shack and get a DX-375. It only costs $100. It covers
all WWV and CHU frequencies. Program the presets to WWV frequencies
2.5, 5, 10, 15, and 20 Mhz. Don't forget CHU at 3.33, 7.335, and
14.67 Mhz. With the presets, you can find the best signal in a few

Remember that the most effective way to induce people to plot
against you is to act paranoid :-).

Subject: RFI from Heath "Big Ben" Chime Clock
To: info-hams@ucsd.edu
I noticed a strange phenomenon two nights ago -- or rather, I tracked
it down, but it's been annoying me for months.
I've been plagued for a long time with a strange signal -- sounded like
"louder" white noise -- that was recieved in a number of places in the
HF bands. Because it sounded like some kind of wierd digital modulation,
kind of like a high-speed modem, I assumed it was some kind of external
interference.
A couple of nights ago, I tuned across the interference, and for no
apparent reason, hit the FM button on my receiver. Suddenly, the noise
became coherent: it was the tone generators on the clock, and I verified
that it was the clock because one of the tones changed in time with the
"tick-tock" sound -- and at the right pitch. The full chime sound could
also be heard on the FM signal. I then did some fishing and discovered
that the signal was repeated every 375 KHz starting from about 14 MHz.
I couldn't find it anywhere below 14 MHz, but it may have been because
of the noise level.
Has anyone else had this problem? And what did you do about it? And
how the heck can I get a 30 MHz FM signal from that clock?!

OK Here are the final comments from my freind and what he decided to do:

SUBJECT: Thanks for the Help (was: WWV request
Well First off I would like to thank all of you who so generously
replied to my desperate query. I am sorry to say I will not be
able to name my first born after anyone because there were so
many who suggested my final solution so I'll just have to name
Him (Nat) or if it's a girl (Netta) after the great Internet :-) .
Well my solution was to purchase a Radio Shack model DX-380. After
most of you said "Any short wave radio can pickup WWV" I decided
to get a nice receiver. It sold for $119.99 (on sale) and has lots
of features and yes it does pickup 2.5, 5, 10, 15, 20, and 25 Mhz.
Again it was frustrating to me that you have to spend so much for
what used to cost about $30.00 with the weather band included. But
if so few people bought them it probably was not cost effective
to manufacture them. Thanks a lot to Radio Shack for discontinuing
them, NOT! Well this is the last you'll hear from me on this subject
[aren't you lucky :-)] but ya'll can still debate the virtues of
low cost WWV reception all you want.
Thanks,
Aaron Henderson

Actually, they seem to contain 6, for a grand total of 7.2V. I assume they
couldn't fit the rest in, and still have a decent amount of storage capacity.
