Prediction system update

I am updating the UK Free TV Freeview prediction system

I am updating the UK Free TV Freeview prediction system
published on UK Free TV

Now my shoulder seems to be back working again, I have been working on sorting out the UK Free TV Freeview prediction system, as seen on UK Free TV Freeview prediction

At the moment it does not cope with transmitters that have switched over, and there are a number of other issues.

A big problem is that it only accepts postcodes, and it is not much use on a mobile device.

I have now written the engine part of the new system, and it works with postcodes, national grid co-ordinates and latitude, longitude.

It can now generate the correct results for any given date for any given place. But they dont look very nice, so the next phase will be to write a number of different output filters.

The standard one will group by aerial polarity, then by the baring, and then group together the number of services that can be received by relevant aerial groups. Clicking from here will display the full details of the services that can be received.

Here is an example output as it stands at the moment; I hope to provide something more live shortly.

As always your comments and suggestions are vital to UK Free TV, and right now would be an excellent time to mention anything you might need or think useful.

The columns are:

  • Channel number
  • Transmitter National grid ref
  • Bearing from north
  • Channel A1=analogue 1 etc
  • Distance from transmitter in meters
  • Name of transmitter
  • Vertical or Horizontal
  • Country code/Region
  • ERP of output transmitter
  • Microwatts at aerial
  • after Group A, B, CD, E, K and W aerial microwatts.
