The symbol shows the location of the Sutton Coldfield (Birmingham, England) transmitter which serves 1,870,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Guide Plus+ PanasonicTV - TxL37E30B.
I have an issue with slow download and limited information on Guide Plus+. Only current and next programs are shown - with slow download - which is obviously inconvenient and frustrating for planning viewing.
This issue seems to have started about 21st Nov 2020. Prior to that some minor download speed was apparent, but full 7/8 day program data was available.
There is much chatter about this on the net, some of which suggests the problem originates with the broadcaster and linked (probably) to Freeview channel changes and/or data transmission changes, and some suggest it is a Panasonic problem. I have my doubts that it is a Panasonic problem since my DVB recorder - also Guide Plus+ - has no problems.
The signal strength of most channels on my receiver is excellent - I live about 10 miles south (B68), and in view of the transmitter.
Could you comment please. Is there a related problem with transmission changes linked to Freeview updates. and will it be resolved in the future (not to distant I hope)?
Thank you for your support.

There is much chatter on the net, some of which you can ignore as it is either pure speculation or comment made without any technical backup or knowledge.
1st, there were no changes to the Sutton Coldfield transmitter around November last year.
2nd, the UHF channels used by the 6 main multiplexes at Sutton Coldfiled have remained the same since the start of DTV.
3rd, Transmission changes over the years have been the addition of the two temporary HD multiplexes COMs 7&8 and a Local multiplex, in Dec.2013, Feb.2014, & Apr.2015 respectively.
4th, The 700MHz clearance changes in Mar.2018 moved COMs 7&8 to UHF C55 & C56 and the Local mux to C36.
5th, Additional transmission of the Local Multiplex was added on C48 in Oct.2019.
6th, Arqiva changed the FEC on COM8 in Feb.2020 to improve resilience of this mux.
7th, COM8 closed at the end of June 2020 for commercial reasons. COM7 will continue for the foreseable future but will close in June 2022 at the latest according to the current OFCOM licence.
8th, Over the years, Commercial Broadcasters have changed the channels they broadcast on Freeview and/or the multiplexes they are on, the most recent of which was July 29th and retunes are usually needed for these. There will be at least one in September.
9th, The 700MHz Clearance Programme in the rest of the UK has now been completed. Sale of the 700MHz frequencies to MNOs for (5G) mobile use is expected to be later this year, but it will be sometime after before any transmissions start from any UK local cells as equipment needs to be installed and handsets available.
10th, Depending on location, to receive all multiplexes from Sutton Coldfield a Group T/Wideband aerial would normally be needed. If reception of COM7 is not predicted/needed, a Group B aerial would normally suffice.
As retunes are periodically needed when Broadcasters make changes, some sets don't always allocate the channels correctly in the the correct LCNs. So if you haven't retuned recently then I'd suggest you do so as follows -
Unplug the aerial and carry out an automatic retune. This should clear memory of previous tuning as nothing will be found. Plug the aerial back in and ideally carry out a manual tune of Sutton Coldfields UHF channels, if you can't manual tune, do an automatic one.
The UHF channels are C43, C46, C40+, C42, C45, C39+, C55 and C48/C36 in the order PSBs1-3, COMs 4-7, Local.
(The + means a 166kHz offsets which TVs do automatically). As you are S of the transmitter, C48 is the one for the Loacl mux. C36 beams N.
The above retune technique doesn't work on some devices such as Youview boxes. For such devices not correctly allocating channels (eg. finding blocks of them in the 790s/800s) a full reset may be needed, but if it's a PVR you may need to reset scheduled recordings.
Did you make any changes to your system/installation around 21st November?
What are the signal strength AND quality figures (or BER if no quality figure) for each of the multiplexes on your TV receiver?
The fact that your DVB recorder is also Guide Plus and is not having problems is not relevant to your set which will have different firmware and the tuner could have a different sensitivity. The fact that the recorder is not having problems is indicative of the fact that there are no problems with transmission!
It's worth considering whether the TV set has too much signal, the figures I've asked for may be indication, don't be confused just because a strength reading might be less than 100%!

R Green: Have you updated your TX-L37E30B to the latest firmware?
Looking at this thread:

It seems a solution has been found:

Chris.SE:
Thanks for your reply.
You have provided me with much useful info (that will take me a while to digest) but confirmed my thoughts that the transmission and dvd recorder are OK and the fault lies within the TV.
I have an additional reply from js, who posted a web address where Pan have released a firmware update - in June 2020. This apparently fixes the problem.

Thanks for your reply.
I have checked the 'https://av.jpn.support.panasonic.com' web site you mention and downloaded the update file for my TV.
Several people on the 'https://forums.digitalspy.com' commented that this update has solved their Guide Plus+ problem. So I have confidence in installing it.

I live south of Banbury but used to be able to get Com7 & 8 from Sutton Coldfield except under occasional extreme adverse weather conditions. I know com8 has ceased but i can't get com7 (channel 55) now - have they reduced the tx power and or the direction of transmission?

Update: aerial had worked loose so was misaligned. Com7 now receivable. It would help if they broadcast it at full strength though.

Richard:
An increase in power is highly unlikely. COM7 operates as a "Single Frequency Network" and power changes would cause different problems in different locations.
Also to make matters worse at present, there's been a lot of "Tropospheric Ducting" around causing interference, see Effect of tropospheric ducting on Freeview | RTIS for a simplistic explanation.
It's likely to continue for a day or two more.

Hello, is anyone else having trouble receiving stations on channel 39? I'm getting a big fat zilch on signal quality from that channel, 618.2mhz, thanks

Can't find any reports of current transmitter problems, are you still having issues?
