ATV's transmitter map
The original map was put up in October 2003 and extended in December 2006. It was then updated in December 2012 for any DSO changes (but that’s the pins not any roads ! ) though there wasn’t actually much that changed. There were a few new repeater transmitters plus some were taken out of use, the most significant being Croydon and Lichfield (both large ex analogue C5 [only] transmitters). In addition a few repeaters changed which main transmitter they get their signal from.
In October 2020 the map was fully updated for the 700MHz clearance resulting in the C/D group disappearing (many more TXs became A or K group) and 12 more TXs became 6 MUX, 4 of which were completely new.
Incidentally we haven’t got anything against Scotland it’s just that we ran out of room to go any further North !
Below is a section of the map around Emley Moor.
The pins on the map are colour coded to show group. Blue indicates a BBC radio transmitter though this not usually shown if it is also a TV transmitter.
There are three different pin sizes to represent low power relays (under 200W), high power relays (over 200W) and main transmitters.
An arrow points back to the repeater’s main transmitter.
A small light blue flag on any pin means I’ve been there !
Power station cooling towers are also on (as white pins) to help get ones bearings.
All 6 MUX transmitters are labelled on the pictures as are 3 MUX repeaters over 200W in power plus the main radio transmitters. NOTE : 3 and 6 MUX refers to the main MUXES, not any "local" MUXES or the "temporary" MUX 7.
All transmitters are labelled on the actual map though I concede this isn’t always that easy to read so to help identify non labelled transmitters try :
Smaller repeater transmitter (with a power under 200W).
A gold disc means it’s a 6 MUX transmitter, but the vast majority only transmit 3 MUXES.
The black collar indicates horizontal polarity (but almost all are actually polarised vertically).
Most do not transmit omnidirectionally
Four adjacent repeaters off four different main transmitters !
One area of particular interest on our transmitter map is that of the South Peak District which shows four repeaters (Tideswell, Ashford, Earl Sterndale and Burbage) off four different main transmitters (Emley, Waltham, Sutton Coldfield and Winter Hill respectively) yet none of the repeaters are more than nine miles from any of the others ! For a higher resolution image use teh close up buttons on the transmitter map above.
This map raises an interesting question as to whether this area of the country is, in fact, the centre of England ! Think about it. All these repeaters must have line of sight onto their main transmitters. It’s also pretty likely that there’s a big hill in the centre of that blue quadrilateral ! If there isn’t then why are all their main transmitters in opposite directions ?
On the other hand, the fact that people off these 4 repeaters may want the local news from what they consider "their area" also adds weight to the suggestion this is the centre of England. Think about it. Those on Tideswell consider themselves Northerners, so they want Look North from Emley. Those in around Ashford may well see themselves as East Midlanders (East Midlands Today from Waltham), off Earl Sterndale as Midlanders (Midlands Today from Sutton Coldfield), and those in Buxton as North Westerners or Lancashire men, North West Today from Winter Hill.
I certainly think the accents vary quite a bit too. Buxton, and NW thereof, definitely sound Lancashire. South/SW of Earl Sterndale a Midlands twang with slight Black Country Brummie influence ? Ashford/Bakewell and SE, they’ve certainly got an East Midlands lilt.
As for Tideswell, and North thereof, that’s certainly God’s country, with the relevant intonation, obviously.
