Chris, your expertise and guidance are impressive!
Question : Is there a website which lists all transmitters on each channel/frequency ?
Thanks!
Michael

Hi michael. This one in theory, if you click on the menu and then select what you want to look at. The problem is some pages haven't been fully updated since B700 there was a lot of work to do and the site owner was struggling as most info on the changes came from pdf docs which are difficult to read and extra info except manually, things are better than they were though, there's also a lot of historic info that is difficult to find elsewhere.
The other "best" one is mb21 mb21 - The Transmission Gallery
It's a brilliant site, normally very accurate, has lots of pictures as well and a fair bit of historic info.
For a comprehensive list in one place, OFCOM's documents BUT they also have some errors, so it pays to cross check with other sources.
https://www.ofcom.org.uk/…xlsx
See the following pages on OFCOM's site for lots of useful info
Spectrum information - Ofcom
For radio, these documents listed here are very useful
Spectrum information - Ofcom /radio-tech-parameters
That should keep you busy for a while :)

Thanks for that, Chris. As you state, it will keep me busy for a while :-) I can do it the long-winded way on this site under "transmitters", but was hoping for a spreadsheet with channels down the left and transmitters along the right. I'll try the links you suggest.
I am in the process of coating my new Blake yagi with corosion-proof gunge, after adding more reflector bars to, hopefully, keep unwanted transmitters out. That, of course won't help with signals bouncing along the ducting from the same quadrant as the wanted ones :-) Freeview streaming is cleverly designed with hurdles to disuade people from watching. Similarly, DAB and internet radios are a pesk to tune, with many not offering more than 5 instant presets. Progress could be wonderful...

Yeah, sometimes you wonder about some of the designers of modern "tech" whether they have any practical clue about using it!
