ukfree.tv reckons September 2011 for Emley Moor, so plenty of time yet :)

Truth be told, it just looked like a fun project. I'm also toying with 
the idea of hacking together a COFDM/DVB-T receiver if I get a bit of 
spare time, and the UV916 looks like it would probably make a nice 
starting point.

And it would also make a nice front-end for a VHF/UHF software radio... :)

Yeah I thought of doing that, but it seems most of the modern TVs are 
using tuners with built-in demodulators, or the whole lot is on one PCB. 
Most of the folks round here got rid of their CRT TVs ages ago... :(

I do have a video board from some unknown ancient TV which *does* have 
one SAW filter on it, but given the scorchmarks on the board, I doubt 
it's still in functional condition. Helpfully enough my signal generator 
only goes up to 20MHz, so testing it wouldn't be particularly easy either :(
