Peter has a very good point here.
Mobile phone installations transmit at low power. We also have a number of
VHF and HF radio stations in this vicinity transmitting at comparatively
high power, and two TV stations running 100 kw ERP. CBers are working at
UHF. There are phone extensions in our homes transmitting at giga hertz.
There are millions of mobile phones; most students are SMSing each other
regularly. Our telephone systems use microwaves instead of copper lines.
Millions of people use microwave ovens which may or may not be radiating
into our kitchens. We have EHT power lines at over 300 kv running past
houses.Where are the clusters of cancers, a disease which has always been
with us, but about which there are no reports of increased incidence of
cancer? Yes claims, but not backed up by scientific reports.
The claims that mobile phone towers cause "clusters of cancers" has not
been established.
We hear little about this here and I am sure that if there had been
"clusters of cancers" someone would be making a loud noise about it. That
is not happening.There will always be those who blame this and that for
all their problems even when it is impossible for what they claim to
happen.They have to have a reason for their misfortune and the pick
something they understand least.
It reminds me of my own brother many years ago who was complaining about
interference to his radio programmes (pre-TV days). He said to me, "It's
that amateur Tresidder over the back of here". I replied, "Nope, not him.
He has only an antenna pole up and he has no transmitter." The fact that
an amateur mast appeared was enough for the neighbours; that ham was
causing interference without even owning any gear!
We have the scare mongers (as usual) here about nuclear power. IT will
cause all sorts of horrible things to happen - people turning into monkeys
etc. Yet these critics are ignoring the fact that there are thousands of
nuclear power stations all over the world operating safely with clean
power. Not for us however.It is a type of superstition not backed by any
credible evidence.
On another subject have you ever heard of an HF radio receiver causing
interference to another BC radio receiver? It happened to me about 50
years ago. I was in my ham shack listening on 14 mhz on night when my
father came in complaining that I was causing interference to his news
service. I said, "Don't be silly, I am not transmitting."
He replied, "It's not you it's the fellow you are listening to." I thought
that this was a funny one and went into where my father had his radio and,
sure enough, there was a yank amateur calling "CQ darg x-ray". This got me
thinking and then the penny fell. I was using a disposals communication
receiver which had a 455khz IF and I had a link between the IF of the
receiver and a Q5er - a Compass receiver with an 85 khz IF. This gave a
high degree of selectivity. However there was a problem in that the short
length of cable connecting the IF at 455 into the Q5er was radiating 455
khz signal into the IF of my father's radio on the other side of the house
at least 20 feet away.So much for the selectivity of the front end of the
BC receiver!
