Hi Pete AD4TU,
I have operated contests both in city locations and in the a farming
area. My experience in the city is that if you run an HF linear,
it is impossible to avoid telephone, HiFi and probably TV interference
with the houses that are within say 100 feet of the antennas- and
perhaps 200 feet in the forward path of a yagi.
In the country you would be unlikely to cause interference
at 1000 feet unless
(a) You have excessive harmonic output.
or (b) It is a very low signal area for TV (on the limit...).
I did get telephone interference at a farmhouse over 1000 feet away,
but the telephone wires were on poles accross my property,
so filters were needed.
Hope this is of some help.
Regards,
Martin ZL1ANJ

In Reston, VA, where I used to live, there was once an absolute prohibition
on outside antennas. Then along came a ham/lawyer who threatened to attack
the entire antenna rule by arguing that the covenants prevented legitimate
reception of free TV. "Why not work with me," he said, "and help me find a
homesite where I can put up a TH-6 on a 70-foot tower without real esthetic
damage?" He got his site, and his tower (painted earth tones to blend with
the treeline). Once the absolute prohibition was breached, and antennas
were permitted on an exception basis, things began to get reasonable - I had
an approved R-5 in the woods behind my townhouse, and there are now at least
a few tribanders on detached homes scattered around. So it's my feeling
that on balance this thing can help, if only because its harder to argue "he
can, you can't" than "nobody can."

Well it was fun I am finally getting the hang of it.
The exchange of names is great and I should be incorporated into the
regular Sprint.
Some contest exchanges are boring but this one keeps you on your toes.
I was mobile and keeping a paper log in the dark with lots of biting bugs
sure make you appriciate operating indoors.
See you next month in the sprint MOBILE!!!

For those interested in learning more about RF exposure, the National
Council on Radiation Protection and Measurement has published three reports
on the subject. The NCRP is a non-profit corporation chartered by Congress
to collect, analyze, develop and disseminate in the public interest
information and recommendations about protection against radiation and
radiation measurements, quantities, and units. The NCRP's recommendations
are often included in regulations at the state and federal level by
reference.
The three reports are:
Report No. 67, "Radiofrequency Electromagnetic Fields -- Properties,
Quantities and Units, Biophysical Interaction, and Measurements" 134 pages,
includes an 8-page list of references.
Report No. 86, "Biological Effects and Exposure Criteria for Radiofrequency
Electromagnetic Fields" 382 pages, includes a 64-page list of references.
Report No. 119, "A Practical Guide to the Determination of Human Exposure
to Radiofrequency Fields" 233 pages, includes a 9-page list of references.
These reports are written for a professional audience, but contain
information understandable by someone of reasonable technical background.
Each report also lists the members of the committee of experts that wrote
the report.
All reports are available from

Next week is the New Jersey QSO Party. A few County Hunters have
asked me for help in some of the southern counties which I will make
a point to operate. More interesting would be to operate from all 21
counties during the contest. I wonder if anyone has every entered the
NJ QSO Party as an All County Mobile and if so what route you took.

Dear Dr. B.
This is really an insidious plot to reduce TVI, etc. complaints. As you
have gotten older you have perhaps weakened in your ability to read between
the lines to obtain the true meanings. It is obviously another plot by our
sinister Dr. B.B.--you know-- Dr. Big Brother. Perhaps too much flatulence

Message-ID: <199608112151.RAA05069 at orion.neca.com>
Hi all:
The recent articles in CQ Contest caused me to think
about something and I'm not sure that I've given
myself the correct answer - to wit:
As a SO/QRP station I do a lot of S&P in the major
contests so I hear a lot of who's where. AND, I do not
belong to a Unlimted Club like YCCC, but I have a lot
of friends who are members.
Now, before I ask the question, let me explain my
station setup. I have a seperate computer for packet -
I use a portable computer for keying and loging.
If I log on to the YCCC network just to pass along
multipliers to the YCCC network, does that place me in
SOA category or can I remain in the SO category?
I don't believe there is an SOA in the QRP category,
but I'm thinking in terms of SO/LP for this coming contest
season.
Thanks for your time..
