Have Your Say
Radio intereference: Having recently purchased a new video recorder, we have been
hearing Indian music through our television, this is obviously coming from the Brookmans
Park transmitter. Does anyone else have this problem and does anybody know how to solve
this or who to contact? Thanks Gary Clifford.
Former BBC Transmitter site nuisance: I have recently come across the previous comments
on the website regarding radio interference and low frequency noise from the various
installations which now occupy the old BBC transmitter site. We are told by the operators
that these transmissions are within safety limits and are not a hazard, but is it not
possible to carry out some local research to provide some definitive reassurance?
Editor's Note: This reply to the concerns expressed above was sent to the site by Bob Horrocks of the North Mymms Green Belt Society.
First of all I am a layman so all I can do is apply what is loosely call common sense. Secondly, it is important to avoid confusion between three types of transmissions.
1: The mobile phones, from the aspects of the thing next to your ear which could be the means of radiation entering into your brain, and the antennas which are transmitting signals in all directions. There are no mobile phone antennas or dishes at the BBC site.
2: The BBC radio station transmissions which go out in all directions, and have done so since the late 1920's causing radio programmes to be picked up on domestic wiring, car radios when close to the site etc.
3: Signals to and from the satellite dishes at Brookmans Park. Signals from the satellites to the dishes should cause any problem to local people, animals, or electronics unless the satellite is sending the signal on a fairly narrow beam towards where the dishes are located.
It might be argued that an area, or unknown diameter around the dish, is in the path of the signal and might be affected by it. I do not know why some dishes have a bigger diameter than others except that the bigger dishes may be needed because the satellite is further away, or is sending a weaker signal.
Signals from the dishes are sent on narrow beams to the satellite, in order to conserve power lost if the signal went everywhere. If a house or tree got in the way it would most likely distort the signal.
So, even though the dishes are at a very shallow angle and appear close to houses in Kentish Lane, my logic says that the signal should not actually be hitting the houses. I do not think the dishes ever point towards any other houses except some in Kentish Lane, but correct me if wrong.
Following our Committee meeting on Monday January 8, as Secretary to the Green Belt Society, I wrote to Castle Communications - the satellite dish operator - to see if they would be willing to expand on the 'letter of comfort' sent to Welwyn Hatfield Council in 2000.
The letter can also be read on our North
Mymms Green Belt website on the 'actions 2000' page.
Top tip - changing phones from analogue to digital removes
all noise from the radio transmitter.
A DETR Inspector recently sought to take account of potential health risks when
considering the erection of a new mobile-telephone mast. However this is currently not
regarded as strictly a land-use planning factor, so there is some legal and other interest
to see if this factor will 'endure' ... Could be interesting.
Re the interference from the BBC, Daily Express on 28 Feb -Gov't research into mobile phones radiation is likely to be hard hitting. We think there should be a knock-on to the BBC site. In the meantime, we will ask that the District Plan be more specific on any limitation for more satellite dishes, and what can be done about current interference. My computer picks up a radio station, and I disconnect it from the phone line to get a clear line. Any other ideas that work? Bob Horrocks

May I sympathise with those of our neighbours who are getting radio transmissions from
their appliances ...
Are any residents hearing increased noise from the radio transmitter? We have had
trouble in the past but luckily haven't heard anything for a year or more. Suddenly on
Saturday February 19th the noise was back and louder than ever. Unfortunately for us it is
only heard in the main bedroom and at night but this time it is loud enough to wake us up.
