Another beta - FM, LW and MW radio transmitters section

I have updated UK Free TV to now use the Ofcom analogue radio database for mapping to add to the TV and DAB maps.

published on UK Free TV

If you visit FM, MW and LW radio broadcasting you will find that there is now a new section dedicated to analogue radio transmitters.

There are currently four types of page.

First there is an "all transmitters map". Secondly there is a listing of "all analogue radio stations":



Thirdly there is a page for each radio station, and finally there is another for each transmitter.



This is still under development, and I would appreciate any feedback you have.

Also...



Now there are TV, DAB and analogue radio mast pages, there is now a system that provides a link on these pages to see the "other" types of transmitter, like this:

Like a good wine, your produce improves with age, Brian. Yet another very useful tool!
Quite a shock to see at a glance how many transmitters there are which will eventually be led to the guillotine by the DAB Revolutionary Council :-)

michael: Thanks.

I suspect that I need to do a "full list of all masts" page now.

Not all mast will come out of service. The community radio services will stay on FM and many DAB transmitter masts are FM or Freeview sites.

Brian,i see your measured powers have quoted for the single element,not the mixed polarization values in Kilo watts.Any reason for this?
All other publications quote mixed polarization values,though the Ofcom site,breaks down the power values between Vertical and Horizontal polarization as well,on FM Transmitters.

Aerilman: The way it works at the moment is that for FM it takes the larger value from the H and V ones provided. If both values would be of interest I can import and display them both.

I know it takes more work,but i think it looks more accurate.For example many of the low power community Radio station FM transmitters, broadcast in the Vertical element only.
I just think you can't get enough Transmitter Coverage maps,so great work.

As a supplementry to the above,the mixed powers of any given FM Transmiter,are not always the same or even.

Aerialman: I can log both values and display them, I was really just trying not to overcomplicate matters whilst I worked out what to do next.

Any suggestions at this point would be appreciated.

Yes,make sure your coverage maps are accurate in the first place!with respect,a lot are not.
For example Winter Hill FM.
Radio's 1,2,3,4,is narrow beam to Blackpool coast and West Lancashire,not omni-directionally as suggested in your map(as proved by BBC FM coverage map1989(3)9211.While Real and Smooth Radio surrounds all of the North-west.
I appreciate the hard work put into this,but accuracy is everything.

Aerialman: The data is from Ofcom, if there is no information in the source data about radiation patterns, I can't include it.

The BBC don't HAVE to provide this information to Ofcom, whereas all other broadcasters do.

Thanks for wonderful maps and data. As an SWL (Short wave listener), these are very useful for trying at DXing and testing out propagation.
