Mr peachey:

Quite a few people are encountering these nag screens which seem to be popping up on the channels on the ArqA & ArqB multiplexes (but not SDN) between LCNs 25-55.

Hello I'm using Freesat built in.

I'm having issues with pixelation especially during rain.
The SD channels mainly have 100% signal strength and 100 quality with only pixelation during rain.

The HD channels BBC one and itv etc have pixelation during normal weather but gets worse when rains.
I have a sky zone 1 mini dish.
The signal on the EU band. CNN HD. Etc has a signal level of 66% quality and 100 % strength. But during rain this drops to 30% quality even to 0% in heavy rain.
I have ordered a satellite inline amplifier but I'm wondering if this will solve the issue or if I need a complete new satellite dish installation

Callum west:

I would be getting LNB Skew and Dish alignment checked in case things have moved in some of the high winds or even wasn't 100% originally.

I refer you to my response to your previous query on COMs7&8
Sandy Heath (Central Bedfordshire, England) Full Freeview transmitter | free and easy

So the updated situation is that the Clearance programme was eventually completed in August. OFCOM have scheduled the auction for sometime in January 2021. The rest of the situation is as previously suggested, until the auction is completed, we won't know if any MNO will have bought the Centre Frequencies (allocated for SDL use), nor will we know what timescale will be involved for such a purchaser to commission such equipment to use the frequencies and so give any 3 month notice as stated in the current multiplex licence.

How up to date is the data here? Compared with what my TV is tuning I see a difference of one through the 30s and 40s, e.g. ITV3+1 is listed here as channel 33 but is 34 in reality (and on…gs). I think that particular retune was quite a while ago?

The more recent shuffle of CCXTV and Dave Ja Vu etc ( also hasn't been picked up here, but maybe that's just normal lag.

Thanks, Ian.

It's not up-to-date. The site owner doesn't seem to have had time to do all the updates resulting from the 700MHz Clearance program, nor any of the recent channels shuffles that Freeview insist on doing!

See Channel listings for Industry Professionals | Freeview for which channels (&LCNs) are on which multiplex.
Sandy Heath's channels are C27, C24, C21, C33, C36, C48, C55 in the order PSBs1-3, COMs4-7. Also note C35 is a Local multiplex for Cambridge from the nearby Madingley transmitter, which you may or may not receive depending on your location.

I haven't been getting your updates for some time (and don't recall having unsubscribed!). Whatever, I hope this post will restore service as before.

Keep up the good work.
