We keep hearing, from Airwave and from certain ‘Government scientists’, that TETRA masts don’t pulse. (Don’t miss ’Hairsplitting’ article on Starweave.com home page.)

Whilst that’s not the most basic issue with TETRA - the Stewart Committee warned against ’Amplitude Modulation’ at around 16Hz, and everyone agrees that’s happening in TETRA mast output - pulsing is generally agreed to be a feature of major concern in mobile communications systems (See also Freiburger Appeal on Starweave home page.)

So how can you and I know who’s right and who’s wrong?

Well, thanks to Rod Burman, an electronics expert on the Isle of Wight, we can actually look at a TETRA mast output and decide for ourselves.

Rod runs an electronics business on the IOW (web ref. below) and has kindly sent me recorded traces from a live TETRA mast. See his email, and the evidence, below.

Dear Grahame

I've just been reviewing your excellent web site as there is a proposal to erect a Tetra mast close to our home on the Isle of Wight.

There is a temporary base station about 50m from a home at Cowlease hill near Shanklin and the people there are already suffering from many of the well known symptoms associated with exposure to this type of radiation, headaches sleeplessness disorientation etc. - and this station has only been operating for 1 week.

Re ‘Oops! What a giveaway’ [Starweave home page] I thought you might be interested in some pictures of pulsed transmission that I recorded from that base station using a simple diode detector and a rather ancient analogue storage scope. Feel free to use them on your web site. Tetra doesn't pulse, Oh really!

Keep up the good work

Kind regards

Rod Burman
