It never was on C48 I'm afraid, and the Local mux is on C35. As has been mentioned a few times around this site, see towards the end of my last comment about this on p313 here Crystal Palace (Greater London, England) Full Freeview transmitter | free and easy unfortunately the site owner has not had the time to do all the updates from the 700MHz Clearance program or correct some errors that appear.

Sirs,
I have LG OLED 55" TV. Couple of months ago the channels on UHF 55 started pixelating and sometimes the channels disappeared completely. All other channels are OK and signal test shows 100% for both strength and quality. Can you kindly investigate the problem and advise? Quality on UHF 55 channels fluctuating between 0 and 45%. The problem is serious for me as it involves BBC 4 and BBC news HD (106,107) which are my favorite.
Kind Regards
Milan Navara

Milan Navara:
Your predicted reception of all multiplexes is excellent, including COM7 on C55. Check that your aerial still looks intact and pointing in the correct direction - bearing 80 degrees for you - slightly N of due E (which is 90 degrees). The rods (or squashed Xs) should be horizontal. You could also do a comparison to neighbouring aerials.
Have you moved anything or introduced any new equipment? Make sure you do not have any HDMI leads close to poorly screened aerial or flyleads. HDMI has been know to cause interference especially to C55.
Check all aerial connections and swap any flyleads which can often go faulty with intermittent connections not necessarily affecting all multiplexes.
Since this started a couple of months ago, some other possibilities could be - any trees nearby on the line of sight which have come into leaf and/or grown taller, any close-by scaffolding or other building been erected or possibly a new mobile phone mast quite close by in the direction that your aerial is pointing.
