BBC1 analogue has been funny earlier this evening (around 6pm). Does the engineering work take place at weekends?

It would appear that MUX 2 (ITV1,C4,C5 etc) has moved to C63, the old MUX 1 frequency.

Further to the above, I've worked out it'll be because Belmont requires 53 for Arq A next week.

Jase: Yes, it's the small matter of stage 2 of digital switchover!

Mux 2 is actually on 63, not 53 anymore.

Briantist: I saw that, but I said Mux 2 (D3&4), not Arq B.

Hi, I wonder what your opinion is this.

I'm in South Yorkshire on Emley Moor, 17 miles away as the crow flies. The new BBC A Mux that started last week at 174kW shows up as 10/10 strength on my Panasonic TV. The quality shows up as poor at first before going to 10/10 after a second. I'm wondering if I'm going to get too much signal after switchover and whether I should remove my 6-way 4dB amplifier.

I cannot ever re-call having a single problem with all the low power Muxes, including the HD mux, which were all at 75%-90% strength. If the low power signals (4/10kW) came in pretty strong, do you think the new high power ones (174kW) will be overload for my sets? I briefly tried using an 8 way splitter instead, with a 12dB loss, and the new BBC A mux went down to about 8.5/10. I've put the amplifier back for now.
