Re: [Sheflug] Digital TV transmitter

These may help:

Gives the channel for each MUX on the transmitter:

Convert the channel into a frequency :-)
	http://www.digitalspy.co.uk/terrestrial/tuning/

Now, tx.mb21.co.uk might also have some information, otherwise your best 
bet may really be to chuck a query to Usenet - either uk.tech.broadcast or 
uk.tech.digital-tv

Oh and a quick google has provided this from uk.tech.digital-tv, which I 
think you'll find very useful (long URL!) - someone else with the same 
problem (different transmitter - Sutton Coldfield - but you'll be able to 
make use of it I feel):

(searched for: digital TV UK "guard interval" "transmission mode")

HTH :-)
