Hi, during the last re-tune we lost the HD news channels and 4HD+1 (group a aerial) are we likely to get them back anytime soon, or do I need a new aerial? Many thanks.

When Arqiva chose to close COM8 some of its channels closed, some moved to COM7. (See my post on p307 Sunday, 21 June 2020 for background to this Crystal Palace (Greater London, England) Full Freeview transmitter | free and easy )
4HD+1 was one of the ones that closed.

For which channels are on which multiplex, see Channel listings for Industry Professionals | Freeview

If you have a Group A aerial I'm surprised that you ever managed to get a signal for COMs 7&8 (was C55&56) unless you are close to the transmitter. You could try a manual tune for C55. You really need a Group T/Wideband aerial, but unless you are doing the job yourself, you may not consider it worth the expenditure considering COM7 is a temporary multiplex.
If you provide a full postcode we can look at your predicted reception.

All:

As the last reminder is several pages back, some UHF channels updates may not have been done to the information at the top of the transmitter page. So -
In the order PSBs1-3, COMs4-7, Local multiplexes, the UHF channels are as follows
Crystal Palace C23, C26, C30, C25, C22, C28, C55, C35 (London Local mux).

Good afternoon. I live in the Hornchurch area of London. I have freeview and get 94 channels via an indoor aerial all the channels show reception as 90% + and often 100%. However I can never seem to get any of the Now' music channels. My indoor aerial has direct line of sight towards Crystal Palace and I live in an elevated position. My JVC Tv picks up the the 94 channels. But strangely my Panasonic PVR picks up 88 using the same aerial. Question: are the now TV stations on some kind of different frequency or do they just get broadcast with a weaker signal?

Hope someone can assist.

Sean.

Sean : The only Now music channel available to you on Freeview is Now Xmas (temporarily renamed from Now 80s) which is on the COM7 multiplex, which is broadcast at Crystal Palace using DVB-T2 (so your TV needs to be able to receive HD channels) but at lower power than the main PSB and commercial multiplexes, as well as being on a higher frequency, with both factors making reception on an indoor aerial more difficult.

Whether this might help, see Channel listings for Industry Professionals | Freeview for which channels are on which multiplex.
And, in the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, COM7, Local multiplex, the UHF channels for Crystal Palace are as follows
C23, C26, C30, C25, C22, C28, C55, C35 (London Local mux).
Try a manual tune on C55 &/or C35. Autotune sometimes misses weaker signals.
