I have just recently had the problem of the recording list partially/completely disappearing.

Last night I only had a partial loss of the sc.hedule today it was the complete list that missing.

In both cases it was cleared by a reboot

I had a problem with this after I had carried out a factory reset about 2 weeks ago. Set up the schedule in the morning after the reset but I noticed that in the evening the schedule was missing, the guide showed the programmes as marked to be recorded but when looking at the program details the dates for the recordings were shown but not marked as to be recorded.

This is so with the recent occurrences, I didn’t leave to chance and did the reboot to clear it but on the earlier occurrence I did a re-schedule of the programmes but missed one which did not record.

A little update… my schedule disappeared again and I can confirm that if I delete any channel, the schedule immediately repopulates!

Given that automatic tuning, even although it asks me to select a region, is dragging in MUXs from another transmitter, I have now manually returned to see what happens. I wish the 4000 had an easy method of showing which MUXs were in use across all the channels.

Fingers crossed….

The same MUX is used for the same channels across the UK. Suspect you mean what UHF frequency/UHF channel number a specific MUX on your box is using. There is normally a way to show this info on a Humax box for any channel you are tuned to. Not having your box I can’t give detailed instructions.

You are correct – I meant to say which MUXs had been picked up and on what UHF channel. The signal test menu item will show you what UHF channel the currently selected channel is on but it’s not possible to change channels whilst in this menu, you have to exit the menu system entirely to change channel and then drill back down to Signal Test again. It would have been nice in the Edit Channel menu to have the UHF channels listed beside them.

Well Done for finding this, if it’s reliable it’ll be the easiest work around so far, especially as another poster mentioned there’s so many rubbish channels to choose from, at least a couple of months worth as and when the problem happens.

The instructions #72 will give the same rudimentary information as per standard on Humax boxes, strength, quality, UHF channel number for the tuned channel in use only. No mention of Mux or whether DVB/T2 or which transmitter. Really useful basic and easy to provide information to help diagnose has always been missing from stanadard Humax products. I expect it’s the same across the board.

It’ll be really interesting to see how this pans out and a great find if reliable until a proper software fix is found.

It’s very easy to identify a single channel from each MUX for your transmitter. You only need to check one from each, that’s 6 or 8 plus a possible local LB mux

Google Freeview on xxxxx (xxxxx your transmitter)

Eg

https://ukfree.tv/transmitters/tv/Sutton_Coldfield/PGSTART2480/

Only channels on PSB3 (and if you have them COM7 and COM8) are DVB-T2

My Schedule was full with 81 events for the past 6 days…….

Today, all but 5 have disappeared !!

I have done nothing different..

Perhaps the 4000 doesn’t like Mondays ?

That’s assuming you know which transmitter you actually use. Searching for it via postcode will bring back which transmitters are in your area, but not which one the aerial is pointing to.

It’s water off a ducks back for someone who already knows a bit about the industry, but others are left printing out available transmitter information and then comparing and trying to figure out what that means in relation to their signal test on their box.

In my partners case, there are two transmitters and a relay and even though she’s a local lass she wouldn’t know or find it easy. Lack of channels >800 doesn’t automatically mean there aren’t multiple transmitters tuned on the box either.

There’s no reason why basic information such as Mux and transmitter can’t be shown along side signal information and it would make life so much easier without guessing or reverse engineering and deciphering multiple printouts. Currently there’s no easy way to find out whether the box is tuned to multiple transmitters and if users delete particular channels it’s not even then possible to tune into that channel and check with a signal test. I’m sure a sagecom STB I had from over 10 years ago provided this information (although I think it struggled to store more than 40 channels)

It’ll be interesting to see if this latest work around helps tomorrow as users bring their box out of standby.

The mux name nor transmitter name is not in the data stream of any channels on the mux, if it was how would it know if it was the parent transmitter or a relay (relay transmitters do not have any way of changing the data they get from the main transmitter, they just shift the frequency and normally change the polarisation from horizontal to vertical). Other than the Mux name, the box would have to have a database to compare UHF channel numbers with specific mux for all channels in a specific area including dozens of relays (totally impractical). If it knew that sort of information it could manually tune all other MUX after finding the first one.

Additionally if you were on a SFN there is no way of knowing which transmitter without checking which way your aerial is pointing. If you don’t have channels over 800 to identify which transmitter you just have to check one channel. Looking at your neighbours aerial and locating your transmitter on Google Earth will easily identify which transmitter they are using.

Without the transmitter name in the data, you would simply duplicate Mux names as well as channel names. How can you be receiving from multiple transmitters without channel numbers in the 800’s, where did it put the duplicates ?

grahamlthompson – 4 hours ago How can you be receiving from multiple transmitters without channel numbers in the 800’s, where did it put the duplicates ?

Simple,

you manually tune and pick and choose, dead easy, no duplicates in the 800’s. i.e. it doesn’t need to put duplicates anywhere because there aren’t any.

Relays aren’t the problem as you well know as they repeat the same EPG and simply relay. no one is asking for a database of relay stations, not too sure where you got this from.

As previously stated the sagecom from over 10 years ago knew which transmitters I was tuned into. As you may or may not be aware a big problem is the EPG coming from different areas on a box tuned to multiple transmitters. Yes I can look at neighbours aerials if I go down the road, round the bend up the lane and remember which orientation I was and quite often you’ll see two aerials pointing in wildly different directions and obviously can’t see those in attics, and yes I can google earth and google search and print out multiple transmitter information and correlate that by tuning to a channel and checking signal on the box and seeing if the UHF channel matches for every single mux. All of this is possible and none of it easy. None of this is a problem for those living within a main transmitter area.

Life would be so much simpler though if the box shared a little bit more of the useful information it already has, which I believe was the start of this point.

Back to the original post…

HumaxUKNW, no one’s asking you to kill your box; however gdavidson’s post is really interesting, you could try deleting one of the really useless channels (there are plenty of them) and see if this triggers a schedule repopulation. I’m sure Captgeneralmark’s method will also work

The comment was re the quote that said auto tuning to multiple transmitters does not always give you channels in the 800’s. By the way auto tuning works it always will.

You can only delete channels in the 800’s , if the transmitter you want happens to have it’s highest UHF carrier at a lower number than the lowest one used one a duplicate transmitter. If this isn’t true then some or all of the channels you want will be in the 800’s. Channels are added by starting at channel 61 and working up to 68. The first carrier found gets the correct lcn, the next goes to 800 upwards. That’s why you have to delete all your auto tuned channels and manually tune. (Which only takes a few minutes anyway).

Since by far the most common source of multiple channels is from relays and you suggested you wanted the Mux identifying, both ocurrences of the same MUx will have the same name and the same transmitter, which is not going to be any help at all. The only information that will help is the UHF carrier channel number, which the box will already give you.

Living within a main transmitter area is not the issue. I live within the main transmitter area of Sutton Coldfield. I can tune Sutton Coldfield, Bromsgrove and Lark Stoke SFN, The Wrekin and the Redditch relay. Due to trees behind my house the much weaker Lark Stoke transmitter is by far my best one.

It does automatically mean that you have multiple transmitters.

Solution is look up your possible transmitters the best will be top of the list.

Note the mux that the most likely transmitter uses for PSB1, go into mamual tune and check the reception for that mux. If it’s OK delete all your channels and manually tune to the list of channels indicated. If not try the next one till you find the best reception for PSB1

New software from Humax January 2017 I understand.

I suspect that is for the other 4000, the DTR-T4000, and not the FVP-4000T.
