The Wrekin and other transmitters

ON Wenlock Edge the wood’s in trouble
His forest fleece the Wrekin heaves;
The gale, it plies the saplings double,
And thick on Severn snow the leaves.

I few years ago I took the kids climbing up The Wrekin in Telford. When we got to the top we found the Wrekin transmitter which serves Shropshire and a lot of the Welsh borders. I remember as a teenager being puzzled that the picture on my parent's new TV was so bad when I could see this mast from my bedroom window. It wasn't until (having unplugged the Belling-Lee connector from the back of the TV) I tried a small PO-1 screwdriver and got perfect pictures I discovered how demodulators in TVs can be over-driven! A 24dB RF pad sorted out our problem.

Anyway - although I only did a couple of weeks in transmitters during my BBC training in the eighties I did find it immensely interesting and so you can learn a bit more at the MB21 website.
