I've been 'high' on Trike a few times :roll: It seemed quite good at the time :lol: The come-down is rough though...
I'm sure you are both aware that it was widely used as an anaesthetic, primarily in connection with childbirth.

I certainly was after a Trike 'high' ;)

I did not actually know of it's anaesthetic use, so there's something I've learned today at least. I don't recall getting an awful lot of work done after I'd been sent outside to get some fresh air so probably wasn't feeling so good, only bugger is I don't remember much of what happened earlier on so can't comment whether it was "enjoyable" or not :D

I spent a lot of my working life exposed to high RF fields. When a fluorescent light tube glows at full brightness with no power applied you know the RF field is quite high!!!

Never have I known any case of it causing health issues; all those so involved are either healthy or lived to ripe old ages and as for making you sterile - definitely not :D

Interesting you should say that, Jim. On a few occasions, where I've stepped into relatively confined areas that have had leaky feeders running, I've experienced momentary dizzyness that's cleared after a few seconds. It's happened in a few locations, and hasn't happened since they turned off the system. I've also experienced the same when entering a mobile phone companies equipment room for one of their 'master' cells*. I've never been bothered enough to investigate whether it's coincidence or not - all I know is that it's happened where there's been (relatively) high RF fields in a relatively confined space :?

I recall my science teacher telling us about a workmate who got into the habit of sniffing trike, said he went mad and went home and murdered his mother. :shock:

This reminded me of CFL3 - Chlorine TriFluoride :twisted: It'll happily burn glass, asbestos, concrete, you, me, the monitor you're reading this on, your house, etc, etc. :eek1: Product of reaction - Hydrogen Fluoride :( I think it can only really be safely transported in iron, copper, and a few other vessels. :shock:
There's a couple of 'entertaining' youtubes about it:


Worth reading the comments section on that one above on Youtube for a giggle :-D

Anyone who worked on valve TVs became impervious to shocks, especially in the days of deep cabinets, you usually managed to come int to contact with something you couldn't see. The usuaul reaction was to go and collect your screwdriver from where you had involuntarily thrown it and carry on with the job.

Another pain were back screw brackets which stood out from the sides of the cabinet and had sharp corners, you did far more damage to yourself with the rapid involuntary withdrawal of your hand than the shock did. I must have had thousands of shocks during my time in the trade.

When I had my HF linear going the shack fluorescent would sometimes glow away merrily, obviously poor SWR :oops:

I to like the test card music, I bought the whole series of Herb Alpert records as a result of the BBC test card. I like the old colour test films too, you can find most of them on you tube. I particularly remember 'Evoluon' the science museum in Eindhoven, belonged to Philips of course, we visited it a couple of times, gave me serious case of deja vu.

Bobins, those that may upset you are likely high RF fields at UHF and your getting into microwave oven territory there so yes, there may be a connection. The jury is very much out on the effects at those frequencies...

All my exposure has been at frequencies below 30MHz and that does seem safe enough but get up to cellular frequencies and it really is tantamount to putting your head in a microwave...

Cor yes! the memories.... My favourite was getting a wrist across the tags on the blue lateral correction coil on the tube neck... That not only shocked but burned too :twisted:

Thanks for that, Jim. That's reassuring to know. Or possibly not [-o<

If it was a while ago and the exposure was brief and you have had no persisting problems the chances are you'll be absolutely fine...

The risk seems to arise from regular prolonged exposure. The odd quick blast of the stuff is unlikely to be any issue at all... If it was a lot of people who had ever been in the vicinity of the main high-power TV transmitters like Sandy Heath or Holme Moss would be in a bad way by now...

I don't know what the average ERP of a cellular (mobile phone) base-station transmitter is now but there seems no issue about planting them in the middle of densely occupied residential areas...

Except of course with the usual suspects, those who complain about everything and use potential dangers as an excuse to get things blocked.
There was an interesting experiment (can't recall all the details now) but they set up a new mast in some college grounds and immediately there was an outcry, nausea and headaches abounded, panic ensued, nobody told them that it was just a post in the ground and not switched on to anything.

Yes, it happens a lot sadly and a particular 'target' of these types are Radio Amateurs. There are many accounts of where they have erected aerials in their gardens and then received the 'visit' and told to desist due to exactly what you describe Gibbo... Desist to the point of removing them, closing down and abandoning their hobby :evil:

Wise amateurs (me included) now practice 'stealth aerial' techniques to conceal them from prying eyes who have no life and nothing better to do with their time and energy...

Mine hide in the attic...

It is a tragedy things have reached such an unfortunate state... Amateurs have always been harassed. It used to be they were the cause of all TV interference problems and now that problem is largely gone with modern TV delivery systems but the tables have really been turned - today's domestic gadgets cause horrific interference to amateurs and you know, they have absolutely no come-back on the perpetrators...

Trouble is, everything from ASDL to LED bulbs can cause interference - virtually everything electronic radiates; often because of bad design or penny-pinching...

I recall a former friend (who was a keen amateur Radio operator) who wanted to set up a mast for a greater range. Most of the people in the area knew him, and did not have an issue with this, but one man did, and would not back down (so the council would not let him have the mast). Every so often my friend would check with the council, and this person still would not let the mast happen.

Several years later this person wanted to have a satellite system, so he checked with the council. The council said that, if my friend were to raise an objection to the dish, they would have to give him the same consideration that the objector had had. The objector then said to the council that he was withdrawing his objection to the radio mast. My friend got this information, and deduced what had happened. He got his mast up in short order, and then got some other equipment prepped and ready. The day after the satellite dish was installed it stopped working. When the satellite people turned up to check the equipment out, they found that, for reasons unknown to them, there was no signal available. Nothing they could do could explain why this was the case (there was another dish within 100' of this site, and it had a good signal). Several years later (the same amount of time of the original objections) the signal returned.
