Apologies for the delay since April! Other issues crowding life and a certain degree of sloth around this particular problem - noli nothis permittere te terere and all that.
I've currently given up with Humax support - like you I'm convinced it's a problem with the Aura (only 9 months old) but, as they can't guarantee that a full reset of the box will retain my recordings (they "think" it will be ok!!) I haven't had the nerve to try it. A full retune with a cleared memory doesn't fix the problem.
In the meantime, I'm content to use Quest+1 - the problem seems to be solely on COM6.
Thanks again
Ted

Ted Slater:
No problem Ted. What a shame that Humax haven't got a solution, or even know what the cause is!
Is it capable of transferring recordings to a USB stick?
If so, you could contemplate that and then try a full reset!
BUT if it is, check the USB recordings first. I've heard of some issues on some devices where HD recordings suffer judder on playback, no idea what the cause may be except maybe the USB stick can't cope with higher bit rates!
If I come across anything else I'll post it.
You could try an email to help@freeview.co.uk and ask them "What are the technical differences between transmission of Quest LCN12 on COM6/ArqB and Quest+1 LCN70 on COM5/ArqA and then explain that LCN12 is missing from your EPG despite retunes. Also ask "And/or are their technical errors in the EPG?" (I know there are some but don't know if they'd be the cause).

Getting intermittent no signal for BBCA channels and occasionally SDN channels, other multiplexes are fine. This has been happening for a few months. It doesn't sound like induction interference as it isn't momentary - once the channels disappear they're gone for the evening, reappearing the next day. Problem happens when using our Humax Aura box and when bypassing the box and plugging the aerial directly into the TV (Panasonic 2013) so I don't think it's our equipment.
Signal strength for other multiplexes around 80% with 100% signal quality, but when we have apparently 'good' reception the signal strength on BBCA and SDN is only just over 50%. Aerial is on the roof and was replaced 2020, aerial guy tested and couldn't find a problem with the aerial or connections, except for some 5G interference, for which we now have the gadget from Restore TV, but this hasn't made any difference. Any suggestions for what we should try next?

In fact, from the Guildford transmitter, the Smithsonian channel is not received. I seem to remember that this channel is no longer broadcast on Freeview.

Mike O'Sullivan: Smithsonian Channel closed completed several months ago. Some of their content was supposed to be being made available on Pluto TV and some on Paramount+.

Elaine Graham-Leigh:
Apologies, we seem to have missed your post for some reason!
This is odd that you are only getting 50% strength on BBCA and SDN when the others are 80%, especially if you've had it checked and the aerial and connections are ok. At least the quality is 100% which is important.
Make sure you haven't got any HDMI leads running close to your aerial leads or flyleads.
Are there any nearby trees on the aerial line-of-sight to the transmitter? I have come across some funny signal behaviour with trees before now!
I assume you are familiar with Crystal Palace's UHF channels. Just to check
In the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, Local multiplex, the UHF channels for Crystal Palace are as follows
C23, C26, C30, C25, C22, C28, C35 (London Local mux).
Just in case you retuned at a time when weather or other interference or engineering affected the signal and you're inadvertently tuned to another transmitter (possibly Alexandra Palace or Bluebell Hill).
Whatever is causing that signal to be down near 50% may make you more vulnerable to interference due to weather related tropospheric ducting causing signals from distant transmitters to be received affecting your wanted signal. There was some quite strong "tropo" last Wednesday, but it'd be surprising if the effect lasted all evening.
When you say the problem happens occasionally, can you give some idea of how occasional? When it happens is it always at a similar or exact time?
Check you don't have any old analogue devices like games consoles, VCRs etc. even an old satellite box with an RF output tuned to a lower channel.

Good evening,
I've recently moved house. The aerial in the loft wasn't working put at different angles.
All houses on this development have loft aerials or some have dishes.
At first I couldn't get anything, then I plugged in an old aerial the kind for mini tvs and I managed to get 7 channels. Then 20, last night I got 160, however, only about a dozen work. Most of the time it says no service.
I have to twiddle the aerial until I get a picture and hope for the best.
My transmitter is Bluebell Hill 5 miles away, I live in close proximity to the River.
Are you able to help/guide me?
How do I subscribe, I found this site by accident.
Many thanks for your time.
Jeni

Jeni Spyby: Some of the houses, notably 91 to 97 Waterside may find it difficult to impossible because to point to Bluebell Hill may necessitate pointing the aerial through the loftspace of the other adjoining properties. That said, the new Gillingham Test Centre transmitter may be available, although it transmits only the PSB multiplexes. To explain this requires going into more detail.
Bluebell Hill is 8km out on a bearing of 201 degrees. The Gillingham Test Centre is 4km out on a bearing of 168 degrees, and it went into service on 11th July 2019.
The first thing to do is to tune the channels in. Once you have the channels tuned to the transmitters, then don't retune because it won't improve reception for the transmitter(s) the TV is tuned to.
Gillingham Test Centre is a new transmitter which broadcasts the three PSB multiplexes on the same channels as Bluebell Hill. The two transmitters work together and are in time with one another, meaning you may be receiving some signal from both. However, the Test Centre doesn't carry the COM multiplexes, meaning if you get them they may not be as good, as you can only be getting them from Bluebell Hill.
The channel allocations for Bluebell Hill are:
PSB1 - BBC One, BBC Two, etc. - C32
PSB2 - ITV, Channel 4, etc. - C34
PSB3 - BBC One HD and other HD channels - C45
COM4 - QVC, Drama, etc. - C40
COM5 - Sky Arts, Really, etc. - C43
COM6 - Quest, W, etc. - C46
Check that the channels are tuned correctly. For example, the signal strength screen may should "C32" when on BBC One (as above). Use manual tuning to try and add any missing ones.
The Gillingham Test Centre broadcasts the three PSB multiplexes but not the COMs. The channels it transmits on are as per those I've listed. Thus, try to work out whether you are getting good reception on the PSBs but not the COMs. Is it the COMs that are not good? If so then this is probably explained by the fact that they are only coming from Bluebell Hill, and that with the PSBs you have the Gillingham Test Centre as well.
