A couple of odd questions about your transmitter coverage maps:
(1)
Is it possible to convert the r,g,b values of your google map overlays back into signal levels in dBm?
(2)
Are the google map overlays scaled the same way for each transmitter; ie does the same shade of green always represent the same signal level irrespective of which transmitter coverage map I am viewing?
Any help always appreciated.
Tim.

I can't receive ITV3 from the Sandy Heath Transmitter on both my TV and Humax. I've tried the reset procedure with no success. Your website doesn't show that you transmit ITV3. Is that the case or is there a problem with my reception? If you don't transmit it, do you intend to do so in the future?

Len Ogier: The multiplex that carries ITV3, QVC, ITV2+1 and others is on low power from Sandy Heath until 9th May.
Try manually tuning to channel 31 if your receiver has a manual tune facility.
