This whole thing has been rolling around in my mind for a couple days. I 
get the idea the FCC is going to find out it opened a big can of worms!

How is all this to be enforced? Will we be required to have a measurement 
taken by some licensed establishment? How often? And what will it mean? 
If someone passes the test with his barefoot rig today, what's going to 
keep him from dragging the amp out of the kitchen cabinet where he hid it 
and hooking it up again? How will the FCC know? "Drive-by testing"?

And where is all the funding going to come from to handle all the 
paperwork this could create for the FCC, which is understaffed right now 
anyway?

Perhaps the law was passed to appease some group, but will be largely 
unenforced?

Questions, questions ...

Message-ID: <v02140b00ae2d6a0e1099@[204.212.59.218]>

One of the documents available for download from the FCC Web server at

http://www.fcc.gov/oet/

is a report titled, "Measurements of Environmental Electromagnetic Fields
at Amateur Radio Stations." Although it appears this report was published
in 1996, it describes the results of measurements of RF exposure in the
vicinity of nine ham radio stations in Southern California in 1990. The
measurements were conducted by the EPA using appropriate test
instrumentation.

I derived the following table from information in the report by calculating
the power at the antenna that would result in a RF exposure equal to the
maximum permissible exposure (MPE). It is important to remember that this
value is for a "key-down" continuously-on CW signal. Since we are allowed
to average the exposure over a 30-minute period for uncontrolled exposures
to the general population, the power during a QSO could be considerably
greater than that given in this table and still result in an average field
strength less than the MPE. In order to examine a "worse case situation" I
picked the largest measured value that was outside of a structure. Often
this was a point directly under the antenna. (It appears that one of the
main concerns was what RF exposures were to the operator and inhabitants of
the house, since many of the measurements were taken in the ham shack and
adjacent rooms.)

Notes:
(1) Measured 3m from vertical
(2) Significantly higher E-field measured near cooling vent
(3) Measured 3.5m from antenna

Based on these calculations from measured RF exposure levels and the
probable amount of actual transmitting time during a 30-minute period, it
appears that maximum legal power could be compliantly used with any of the
antennas, except the 4-meter high 40-meter dipole. Even this antenna might
be compliant at full legal power depending on its position relative to a
property line.

hi;

it isn't the MSG in the meat tenderizer that's
the "active" ingredient against wasp venom.  the
important component is *papain*, a proteolytic
enzyme.  besides denaturing wasp venom, it also
tenderizes meat.

And therein lies the problem Wayne. We don't all have access to HIGH-PRICED
instrumentation to demonstrate our compliance when our neighbors (and their
HIGH-PRICED attorneys) discover your new rules, and use them to batter us
over the head. It's the "IRS" problem - They can just CLAIM we're guilty,
then we have to PROVE we're innocent!

I hope you're well satisfied with the genie you have let out of the bottle.
Too bad you couldn't swallow your pride, and let ARRL deal with the FCC.

Guess that explains the '599 qth' contacts. There werent many but a few.
Good to see newcomers are reading QST to get contest rules and then getting

>From a medical point of view, this is how it works:
Adolph's contains an enzyme called papain (comes from either the 
pineapple or papaya). It breaks down proteins, including bee venom.

Another helpful thing is the goop in an Aloe Vera plant. Just break the 
leaf open and apply to sting or burn. 73/ Dr. Barry
