If your running 100watts, but calculate if you were actually running QRP at 5 to 10watts. What’s your exposure to EMF then?
Wonder why they would develop such a survey. What’s the purpose, or possible agenda? I had heard some time back they wanted to reduce your licensed output level. For example, your 400watt Max to 10watts. If they did that you’d be forced into QRP. How could they do that? Government can do anything cause what are you gonna do? Start a revolution with rocks? Sounds crazy they would try, but that’s what a UK ham had mentioned and plays in my imagination why they’d introduce curriculum.
Large amounts of EMF exposure to humans have proven to effect a persons consciousness and other physical issues. Creates paranoia and other health issues. Wonder if that’s going to be their argument on a health level, or environmental in the future.
None the less, I think that’s a waste of time. Hams that been doing this for over 60 years are alive and well. So what’s the purpose?
I think you are misunderstanding me..... There have been rules governing maximum EMF exposure in existence for many years, but they have only been applied to commercial users - cellphone towers, TV transmitters - that sort of thing. OFCOM have now decided that all users of radio transmitters must obey them - I've also received a notice of licence variation for the VHF and radar installed on our sailing yacht.
OFCOM (our FCC) have tried to make it easy - they have published a simple spreadsheet to help. You key in information about your transmitting equipment and it churns out a report designed to indicate if you need to get an expert assessment carried out. On our boat, for example, I key in the power output level and frequency of the VHF and the height of the antenna above deck level and it tells me that I don't need to go any further - the minimum separation distance for that frequency and power level is 1.5m and the antenna is at the top of a 15m mast, so there is no risk to the public.
Where my ham station is concerned, I keyed in the details of the transmitter, feeder, antenna position and antenna design and it told me that it estimated that no more than 10W of the 100W output of my transmitter would actually get radiated into the aether and, hence, it really didn't think that I needed to go any further with the assessment!
