In April 1956 in Wrotham, Kent UK what went into Operation to make things a little clearer for People?
In fact the claimed performance numbers quoted by the Document I have, are Impossible Today even though Technology has improved

I found this from 1955 not 1956

Wrotham was the first station in the UK to broadcast on VHF/FM, with three services beginning officially on 2 May 1955. It broadcast the Home Service (now Radio 4), the Third Programme (now Radio 3) and the Light Programme (now Radio 2). The frequencies it used for these programmes on FM in 1955 are still in use today.

Thanks for that heres the Original printed Official BBC press release The date looked like 56 and that what I stated

As for the Listening range VHF on average is good for 35 Miles in a straight line then fades badly (thats the High powered transmitters) Only extends if there is a repeater (low powered) Transmitter Fitted for Radio
Rule of thumb is...Can recieve if your area can "See" the Transmitter Mast and VHF Rarely Skips (Propagation) as do the Lower range

Beyond me Bar the Basic mechanics

In free space, all electromagnetic waves (radio, light, X-rays, etc) obey the inverse-square law which states that the power density of an electromagnetic wave is proportional to the inverse of the square of r (where r is the distance [radius] from the source)

Jenny? I do remember some houses on our street(Near Blackburn) fitted with this Subscription Radio Circuit (I think ?) was still in Junior school and I thought Its a council Community Music service (and the Sound is very clear) A partially solved Mystery I think it dated from Pre 1960 (when we Moved in)
