I only saw these grouped to the area I worked, the transmitter was Winter Hill, BBC1 CH 12 ITV CH 9 and UHF Group C/D.
I think the Band 3 was broad enough for the CH 9-12, I cannot see how they woukd have tuned it to two seperate channels, group C/D was I think CH 48-68 could have been 49-68, but too long ago to be certain. The UHF Channels in use were 55,59,62 and then when it arrived 65 for CH 4.
