Survey Question
Current Survey Question

Looking back to YOUR start in Ham radio, with an eye to "...the way things are in the world" to-day, do you think that you would have become an Amateur radio operator if you were somehow miraculously the same age as when you started, but in 2014?

Recent Surveys

R.F.I.---the continuing scourge of Ham radio, be it "traditional" horizontal oscillators of TVs going back to the 40's, or the raucous din of to-day's plasma televisions, exercise equipment, lighting systems, furnaces, electric fences, power line leakages, AD NAUSEAM. How have YOU handled cases where somebody's electric contraption seriously hampered YOUR on-the-air activities...?

Manager - VK5LA
Andy Williss (VK5LA) Welcome to the Survey Page.

The goal is to help us all gain a
better understanding of the ham
community... what we like... what
we don't like... about various
aspects of our hobby. Let's make
it fun and maybe kick up a little
dust once in a while. I hope you
all will participate and enjoy the
questions.

Please enter your ideas for future
survey questions yourself (click on
the "Enter your idea" link just
above) or send them directly to me
at surveymaster@eham.net .

I often get comments that there is
a commercial interest in the survey
questions and that some of the
questions are "rigged"...I assure
all eham users that the questions
are
in no way influenced by any
company, person or persons.
The questions in the survey all
come via contributions to eham or
are just plain made-up by your
humble survey manager.


Please note that there are many
potential surveys in our queue, and
many of them are duplicates.
Sometimes we combine several
questions into one. We at eham.net
make every effort to present all
content in a way that will be
easily understandable and useful to
an international audience.

Survey Comments
Interesting comments here
Most of these comments do not surprise me. So
much of the population is living in the dark
now a days. Common sense has gone out the
window. It doesn't surprise me that we have
the health issues and Government issues after
reading these comments.
I have worked in EMC for many years, I have
done studies on myself radiated with high
levels of RF for long periods of time. The
thing that most are missing is that the
culprit is the Stress that a continuous RF
field puts you in. Why do think the incidence
of cancer is so high? It is the constant
stress on the human body caused by today's
society. EMF exposure just cause more stress
on the nervous system which in turn causes
sleep issues. I know many hams that stay on
the radio for all hours of the day and night,
never getting into the rem sleep state
required for good health. AS for someone else' s comical comment here, that is
probably why you see the large bellies and
the completely out of shape individuals at
the Ham fests...hi Hi. I have experimented
with sleep studies for many years now, I will
tell you that EMF exposure is a definite
factor in poor sleep due to stress related
issues caused by long high field exposure.
Just wait until the labels finally appear on
the cell phones just as it took many years to
convince people that cigarettes caused
cancer. I have developed a machine that makes
you sleep like never before, we have been
using it for almost 3 years now with unbelievable results. Sleep is your most
important issue in your health next to
staying away from Pharmaceutical drugs (the
biggest killer ever)and proper nutrition.
Without saying too much about this device, it masks EMF exposure while you sleep. I could
sleep through a thunder storm with this
device running. All you non believers in EMF
should evaluate yourself, how do you sleep?

Junk
Wow! There sure is a great deal of junk science here.

No wonder people think cell phones cause cancer. Love the part about EMP and Faraday shields.

The fact is, if the RF doesn't cook you, you really should just worry about something else.

Posted by W8JI on November 20, 2011

HAM RF levels
1-30 MHZ low band RF is a big wave , you do not catch much of it. , now VHF and up , you absorb the entire wave , cell phone next to your head
is by far the worst... we can only hope the
corporate CEO will all drop dead in 20 years from non stop cell phone abuse.

Posted by KO6KL on September 10, 2011

EMR/EMP
I will guarantee that 99% of the 65% that say their station is "compliant" are not.

Unless your rig is IN a complete RF "
Faraday Cage". You ARE NOT covered. That means taking the rig out of your operating station and putting it in a RF SEALED enclosure, like a 20mm Rocket case that has ground straps from the lids to the body. Anything less, you are NOT protected, especially from EMP.

Posted by AD5TD on September 10, 2011

EMR??
What the hell is EMR? Sounds like another load of tree-hugging, mamby-pamby BS, concocted by liberal whiners that never shut the hell up about whatever is currently killing us. Someone please tell these fruits that we're all gonna die eventually, anyway. Doesn't matter how much wheat grass you eat nor how much "bad stuff" you avoid. You're time on this planet is limited so stop pissing and moaning and enjoy it. Or at least let the rest of us enjoy it. O.K.?

Danger From Antenna
I think I am in more danger of the tower falling on me as I walk by someday then from RF killing me.

I do think RF can cause you to loose hair on the top of your head and make your belly grow!

I see a lot of guys that look just like me at the swaps, it must be the RF!

Really wish WY3X would point his antenna away from me!

I ran 3 250kw hf transmitters and we also had a 1mw tx, and I'm still here!

Posted by N4EV on August 27, 2011

For a moment I really cared...
As a Health and Safety Professional (forgive
the caps.) I had to act in a duly caring way
when a friend of my son's, who is a tower
climber and deals with commercial
communications, suggested that I might be
over-exposed to EMR at my home station, due
to a vertical antenna I am running.

I have performed the calculations for some
pretty hefty commercial gear that runs on our
company's sites around the world. None posed
any problem, so I failed to see how my 100W
would pose much of a problem. I did perform
the calculations. Anywhere outside of a few
feet I will never have to fear, no matter
what the conditions.

Is there a problem? In most cases no.

You can find out exactly how you fair by
doing a Google search with your station
parameters and the Google calculators will
reduce your fears to calm scientific
certainty.

Emr not a big deal
there are real hazards, but we are talking
serious power in VHF or higher and aimed.
Or in a microwave oven.

First you have to be in VHF to low UHF to be
even concerned at the 100W level or higher.
Even then with 1kw and 14dbi of 2M or 70cm
gain you're not likely standing in front
of it.. Most people doing this run towers and
usually 50-60ft or more of vertical distance
is enough. If not they are usually aimed up
(moonbounce).

At HF, it's not an issue unless you live 10ft
from the dipole at 1kw. I'd suspect the
burns from the hot mic would you give you
hint then.

There is an on line calc for this and it's
fun to try number to see what _may_ be a
hazard. to hit that threshold you need to be
at VHF, runs serious power and serious gain
and be at stupid distances from the business
end of the antenna aimed at the person
(rather than some useful direction).

What EMR?
I have a friend who worked in ship navigation using the 420-450 MHZ Band. After his third child, he tried to sterilize himself by standing in fron of the log periodic loop antenna running 20 KW. It did not work and he had another child a short time after. So much for EMR.

It's not high on my to do list to check.

Posted by N0AZZ on August 15, 2011

its a bit warm in here
I could imagine if your feeling the effects of radation, you have a prob, but who am I to say, I ran 600+ ave watts mobile, and the only heat I felt was either directly from the heat sink, or when I rolled my window down. I say, don't touch your antenna when your transmitting, and your probably ok. (unless you feel unusually hot when transmiting, and its cold out)
73 and keep the qro alive!

Posted by AE7QT on August 13, 2011

Answer?
The question was, "Is your station safe". but they did not include an option for NO! Why not?

BTW, I run an Alpha 8410 and legal limit with a beam most of the time and I don't lose any sleep over EMR safety. I do, however, worry about some government entity forcing us to cut back on the power, or telling us to stop transmitting, because THEY think our RF is unsafe.

Industry Canada "Standards"
Hi Sean,

Many thanks for that info---it was just exactly as I'd
suspected...

Our licensing body has thrown Canadian Hams to the four
winds with this latest capitulation of their mandate.
Consumerism rules---non-technophiles reign supreme-
--ignorance conquers all, I'm afraid!

Varying opinions
VHF RF power (144 mhz) isn't harmful--unless you're running way more power than you should be into an antenna low enough to expose you to that power. It's when you get up into the UHF bands--above 440 mhz--that you get into the area of RF radiation that may really affect you.

And still, hams have been running 50 watts of RF power at 440 mhz into mobile antennas for years, and there has been no reports of harm done to anyone.

I really wish that this super cautious attitude of the government would stop. It's killing the industry of this country--and now it's going to kill the pleasure of any hobbies we have that may be higher tech. We're already seeing warning that we shouldn't be so near to CRT monitors--next we'll be seeing that computer towers and desktop units are dangerous.

Posted by K1CJS on August 8, 2011

Nope, and don't care. I agree with N5TSH. -WY3X

Attention: VA5LF
Please share your recent experience re. Industry Canada, for MY personal benefit at least, please...!

Were your travails the result of some neighbour who disputed your erection of a tower...?

At one time, long LONG ago, our Canadian licensing body was seemigly on the side of Amateurs---it seems to me they've caved-in to pressure from cash-strapped policies from on-high, & poltically-correct "consumers", and are now merely heeling under the universal dumbing-down of everything around us...

...But I could be wrong...I sure do hope so.

More details, please...!!!

~73~

Posted by VE3CUI on August 7, 2011

Yes, I do comply
And I have a letter from Industry Canada to prove it. Too
bad I had to be off the air for 7 months before they got
around to measuring that I was at most 2.3% of Safety Code
6 (EM radiation exposure guidelines from Health Canada)
levels.

Now another local ham will probably get to go through the
same thing. Just IC's way of punishing those who dare to put
up a tower, methinks.

Posted by K8NDS on August 4, 2011

Ummm... yea right. My experinence with the AR FP-2000, FP-2080 & FP2083 isotropic e-field probes is that they "average" the measured field strength. They simply can not be relied upon for accurate field strength measurements of modultated radiated RF signals of any kind.

Being Careful
For the average ham - If your top HF RF power is 100 Watts, since your output is not continuous and you do not operate next to your antenna, you should have no problem. If you use a linear amplifier, well, so you do your homework, and still no problem.

What I suggest you watch are VHF and UHF RF power. Ten, six, two, one and a quarter meters and maybe throw in seventy cm for good measure - keep your RF fifty watts or under and your head out of the antenna, and you will have no problem. Show some extra respect for VHF and UHF, because that is where things can be unhealthy. My opinion.

Posted by AI2IA on August 6, 2011

Does it feel warm in here....?

Posted by W8AAZ on August 5, 2011

Cell phones in your ear
I don't think that you have to worry about kids getting asima for Ham Radio.
They all have cell phones in there ears all day long. The field in your head for 600 miliwatts with time exposer is greater then 1 kw running next door intermittently. Put a e-field probe right next to your cell phone, then put one 50 ft from 1kw antenna; that will tell the story.

Posted by K8NDS on August 4, 2011

I don't know
I believe I should worry more about the cell tower I can see from my house than 100W on 20M.

Posted by WA2E on August 4, 2011

EMR Safety
If you look at actuarial tables that pertain to health risks, EMR doesn't even show up when compared with smoking, automobile accidents, drowning, fire, exposure to harmful chemicals in the air and water, food poisoning, insect-born disease, cancer, etc. Numerous studies have been done on cell phone exposure and been inconclusive or negative. And the very short wavelength EMR is only millimeters away from the brain! I also agree with the comments of VE3CUI as it appears that a little RF can actually be beneficial! Finally, I would suggest to those who are really concerned about lowering their exposure to EMR, they should allow for increased tower/antenna heights. As EMR follows the inverse square law, the higher the antenna the less EMR you have to worry about, squared.

Posted by VE6TL on August 3, 2011

EMR
Like global warming ... CO2 ... etc ...the studies all come from some egg heads in a think tank .. all they ever lead to is another request for more federal grants to study the "problem" .. which was created by them in the first place.. there is a whole segment of academia who make a very good living "studying" all these so called threats to the human race funded by our tax dollars...

Posted by K1VV on August 3, 2011

What if...
one of the answers was to be "I really don't care, it being run the way I always ran it--and I haven't kicked off yet!

Posted by K1CJS on August 2, 2011

EMR = BS
I, too, have yet to see ANY PROOF to all this.

I ALSO gave up on trusting ANYTHING these "so called" scientist ever say, YEARS AGO, as I find them even MORE "flip-floppy" than your average politician!

How many remember when they used to claim that RF radiation could heal - broken bones, at least - maybe more?

If one stopped to think about it, we are constantly BATHED in EMR. Don't you think that ANY effect, negative or positive would be showing up by now, if there really WERE any?

Posted by WD8OQX on August 2, 2011

Are You Kidding Me...?!
"The Canadian Amateur"---The Radio Amateurs of
Canada's version of QST magazine up here inThe Great
White North---regularly publishes a compiliation of
recent Silent Keys, but with a twist: the list also includes
the AGES of the deceased Hams.

Awhile back I looked at the ages of all of the deceased
Hams' ages from just one issue of TCA, & averaged them:
it was something approaching the average age of death
for the average Canadian male---78+ years, if I recall
correctly.

Now, I'll be the VERY FIRST to concede that mine was
HARDLY a definitive scientific study, or the "last word" in
this matter...but what struck me at the time as being VERY
interesting was the fact that a disproportionate number of
guys (and gals) who probably started as Hams in their
early teens did NOT climb up into that great big Ham
shack in the sky until the reached their 90's.

My question is this: can the ARRL / EPA / WHATEVER
"nanny authority" pressing this issue back their claims &
concerns with even a modicum of historical fact...? Or is
this just another knee-jerk reaction that will generate
even further NEGATIVE knee-jerk reactions in the public's
personna of Amateur radio...?

Interesting, that this came up on survey.There is article on now saying emr causes asima in kids. Wait till homeowners nazies get ahold of that . I run onely ten watts, figure not likely to be a problem. Onely if I , cough cough gag hack , get an amp. kg4ymc . I promise if get a job , I will subscribe or buy stock in eham .
