DEP May Impose Fees on YOU!
The Department of Environmental Protection and Energy in New Jersey is
proposing a fee pertaining to owners of RF generating devices. In summary,
the proposed rule will require the owners of sources of radio frequency
and microwave radiation between the frequencies of 300 KHz and 100 GHz
that have the potential of exposing either workers or the general public
to radiation levels in excess of the regulatory limits specified in
N.J.A.C. 7:28-42 _Radio Frequency Radiation_ and all owners of radio
frequency and microwave heaters, sealers and industrial ovens to register
those sources with the Department within 60 calendar days after the
effective date of this rule.
The owners of all units that are subject to this rule shall be assessed an
initial registration fee and will be required to provide technical
information to the Department. After the first year of the program, the
owners of registered units will be assessed an annual renewal fee. The
amounts of the proposed fee are based on the services to be performed by
the Department. A copy of the Department's calculations of the initial
and annual renewal fee is available for inspection by the public at the
Bureau of Environment Radiation, 729 Alexander Road, Princeton, New Jersey.
The Department requests that any interested person telephone to make an
appointment to review the documents.
A public hearing to discuss the rule will be held on January 11, 1994,
beginning at 9:30 AM, in the Department's Public Hearing Room, 401 East
State Street, Trenton, New Jersey. The Department will accept comments
on the proposed regulations until January 20, 1994. Comments should be
addressed to Janis E. Hoagland, Esq., Administrative Practice Officer,
New Jersey Department of Environmental Protection and Energy, Office of
Legal Affairs, CN 402, Trenton, New Jersey, 08625-0402. If you have any
questions regarding the applicability of this rule to your organization,
you may contact Ms. Deborah Wenke with Radiation Protection Programs at
609-987-2101.

distances 5 cm or greater from any object.
7) Where electromagnetic fields are present at more than one frequency or
for broadband fields, the fraction of the RFPG incurred within each
frequency interval shall be detrmined and the sum of all such fractions
shall not exceed unity.
Although initial and annual registration fees are not outlined for Amateur
Stations, Amateur Radio is mentioned in several sections of the DEPE
proposal as being a significant source of radio frequency radiation that
poses health risks to the general public. As a reference, the median fee
for commercial users will be approximately $500 per antenna if this proposal
is passed.
The proposed new rules will provide the Department with the financial and
informational resources it needs to enforce the radio frequency radiation
protection provisions of N.J.A.C. 7:28-42 and are therefore expected to have
a positive social impact. The more familar applications of radio frequency
radiation are AM and FM radio, television, amateur radio, microwave ovens,
radar, microwave point-to-point and ground-to-satellite telecommunications
links, and other communications services. Radio frequency and microwave
sources are also widely used in industrial heating and sealing operations.
The steady increase in the number of these sources, coupled with a better
understanding of their biological effects on human beings, has heightened
concerns in the scientific community and in the public about the potential
adverse health effects from exposure to this type of radiation.
Nonionizing radiation sources have steadily increased in number and their
uses have so diversified that a general increase in radiation levels in
the environment has occurred. Extensive radio frequency radiation
measurements made by the EPA have shown that the sources most likely to
produce the highest environmental levels are television and radio broadcast
stations. Other significant, but less intense, sources of radio frequency
radiation are transmitting satellite earth station antennas, microwave
point-to-point communications antennas, cellular telephone cell-site antenna
base stations, amateur radio stations, navigational aids and radar.
Radio frequency heaters and sealers are generally located indoors and it
is not currently known how intense the radiation emmitted by these is
outside the buildings in which they are housed. Because the new proposed
rules will support a staff to ensure that all of the aforementioned sources
are in compliance with the radiation limits set forth in N.J.A.C. 7:28-42,
the new rule will have positive impact of reducing the levels of nonionizing
radiation in the environment.
I suggest that comments be directed directly to the Department of
Environmental Protection and Energy of New Jersey as outlined above.
Those outside New Jersey aren't out of the clear on this issue because if
this proposal passes, it could be justification for a national ruling on
radio frequency radiation that could KILL Amateur Radio for good!

Hey Nick!
For $6.95 you can get the entire US 2M repeater directory from ARRL. I got
mine in the local radio store here. Then you would never be without a
guide to wherever you may be going.

Has anyone explained power ratios to you?
Here's a tech note (from me to you): Power ratios (or dB as they're called).
5 watts RF output power is the maximum legal power output
as measured into a 50 ohm load. Decibels or dB are a measure
of ratio. If you increase your power from 5 watts to 10 watts
the ratio is 2. In dB the number is 3. This is derived with
logarithmic methods.
10 * log(10) power(a)/power(b)
If you look at your S-meter on the radio, it is calibrated in
S-units from 1 to 9 and above 9 in 10 dB increments. Each S-unit
is typically (or should be) 6 dB or the equalivant of a 4 times
increase in signal power.
If for example, you are only S-7 on your buddy'sradio, to get
to S-8 (and this assumes your radio is putting out 4 watts now
you would need to increase your output to 16 watts. And again,
from 16 to 64 to get to S-9. A 10 dB increase is equavilant to
a 10 times power increase, so then (starting again at 4 watts and
S-7) to get to 10 dB over S-9 would require a total increase from
4 watts to 640 watts.
The quickest and easiest way to increase the effective radiated
power (E.R.P.) of your station is to see to it that the powr you do
put out goes in a direction that makes a difference. Obviously with
a vertical antenna, most of the power goes every where else but to
the person you wish to talk with. A simple dipole with split the
power evenly from towards and away from your target. More elaberate
antennas (Heh heh, Moon rakers etc) are just better at directing
all (well actually most) of the power in a single direction.
Now, back to your radio. Assume that it puts out 4 watts. If you
peak things up to where it puts out the legal 5 watt max, you have
about 1 dB of effective improvement. (Note your radio would have to
be down to 1.25 watts to be a single S-unit below what 5 watts would
result in.)
Still want to poke around in the radio? Do you have the service manual
for it? Although most of these radios are generic once you open them up,
I like to have a road map that matches the radio before I start twisting
knobs and things.
Have a nice evening...

Subject: Portable Repeater Help
To: info-hams@ucsd.edu
A friend and I are having a wonderful time playing with ham radio
projects. We started with a couple of antenna projects and we are moving
up into the bigger (read expensive) projects. We are currently building
a dual band 2mtr/70cm amp for mobile (or base) operation. We allowed
our imagination to run some and thought having a portable repeater might
be over some use.
So we have most all the parts required to fab a repeater, and would
love any constructive idea's to help us along. One big part we lack is
the duplexer. If anyone has plans for one we would love to look them
over. If anyone has a set of cavities, we would entertain the thought of
purchasing them.
The current plan is to put the amps in a 20mm ammo can and the
duplexers and control circuitry in another ammo can and interconnect them
to make a repeater. With luck we will have room for the 12volt deep
cycle rv battery!
We have read through the ARRL handbook and the antenna handbook, but
still have some questions on the best approach. So if this is a project
you worked your way through please drop us a note.
Thanks

They are just terrific. I have not had one yet that did not exceed their
very conservatively rated capacity. They last about twice as long as
a NICAD. The batteries never get hot in the recharger. On my CD, a pair
of AA's lasts about 8 hours. I am very pleased with them so far.

A data point.
They are out there, but something or someone has to draw their
interest. With the advances in electronics and communications, the
fascination of the crystal radio isn't the attraction it once was. I first
became acquanted with ham radio when a fellow student set up his rig
at a research site we were working at one summer (now 20 years ago). He
strung a dipole antenna between two lighting rods, and he was on the
air. We had a great time just watching and listening to him work the
bands (voice). But due to -many- other activities and interests, it was
never something I pursued (like I really need another hobby....).
It looks like I, and six to eight 11 and 12 year olds, may soon have
one, though. Tonight we take the written Novice exam, on our way to the
Tech No-code. My son's scoutmaster holds a General ticket, and for
several years (it could be *many* - he's been scoutmaster of this troop
for 25) he has been offering ham classes to any interested scouts. He
piqued my interest again when he worked the "Jamboree on the Air" from our
campsite in the Shawnee National Forest in southern Illinois. So when my
son (11) said he wanted to take the ham classes, I thought "here's my
opportunity", and it's a great father/son thing to boot. I asked if I
could sit in (the more the merrier - I'm not the first father to do it).
So we have been meeting once a week since October, going through the
question pool. The boys have been able to see and feel real equipment,
listen to transmission, and see packet radio in operation. Most will
probably not go on to learn code, because the idea of immediate
communication on 2m is more attractive right now. But so what? They all
will have learned some basic electric theory and have some understanding
of antennas, radios, and radio transmissions. The opportunity to
learn code will be available to them if they want it. Some will go much
further.
John's type of experience is what discourages young enthusiasts. The
older hams with "attitude" have to realize that these aren't the "good old
days" any more. Electronics and communcations capabilities have improved
exponentially in the past 30 years. 11 and 12 year old kids today know as
much about computers as the older hams once knew about radios when they
were that age.
My son's troop now has numerous licensed hams, although I don't know
how many are active. I do know that several have joined the local amateur
club and try to be active in that. And, it's all due to one "older" ham
taking the time and effort to interest some kids in the hobby.
So, if everything goes well, we will all pass our Element 2 exam
tonight. Wish us luck!

Yea and Hooray! My area has loads of young voices, even a couple with
advanced and extra licenses.
I can hardly keep track of my HT because my 12 year old covets it and even
hides it in his room at night (KB7ZIU). My 22 year old (KB7ZIV) is not
quite so ambitious. Come on Christmas! so I can let them tear the
wrappings off their Alinco DJ-180T's!!!! I want my radio back. My 12 yr
old uses the packet station like he was born under it, talks with oldsters
and youngsters alike, and is now studying his code. Heaven help my HF rig
when he gets his code!! I am looking for a backup rig I can put in his
room and another HF antenna for the roof!
We have lots of other 8-16 year olds that ride the airwaves and not only
get a kick out of talking to each other, but all the older hams in the
area, as well as HF DX in South America etc. KB7WIG is working on his
general class, KB7WCV talks to us occasionally during our commute and also
has his tech+ and a TS-520. KB7WYE got his license at 13 and is an Eagle
Scout, talks to both me and my son when his mom is driving him to school.
An 8 year old girl passed no code tech at the last testing session ----
they are there guys, at least here in Utah, and we are loving it. A lot
of these hams have dads who are also hams. And there are a new breed of
single women as well as spouses who have gotten their licenses in the three
valleys here in the west.
We welcome the new voices and congratulate them on licenses and upgrades,
and talk to them whenever we get the chance. Saturday night, one club
staged a North Pole "link" with Santa Clause, and used a net control to
have kids of hams talk to Santa over the 2M repeater. Think those kids
will remember ham radio and a chat with Santa?
My 12 year old is putting me to shame: he registered with ARES and checks
into their net every Tues night (past his bedtime by the way), but I kinda
look the other way.
These kids are smart, pick up professional operating procedures, and often
sound like seasoned hams, putting some of the old timers to shame who have
picked up some poor radio habits. Don't be afraid to let the kid next
door, or your own, talk on your radio. It seems to be habit forming.
Don't forget to lock the gear up though, kids have a tendency to use it
when they want, licensed or not.
Cheer up Drew, and all you others. Encourage the youth, and you will get
more than you want. Forgot to mention that many scout troops have a radio
night, and arrange to have the scouts listen and talk on one of the
repeaters as well as HF. Just takes some organization and some hams who
care.
