^ Sometimes yes and sometimes no, it still cuts it off!
Steve983 – 2 hours ago »
I get the same problems whether I use manual or auto tune
The idea was to see if there are duplicates in the 800’s after an automatic tune which would indicate multiple transmitters.
Have you carried out a default-reset/factory-reset, 2nd thing to try after a power cycle if there are problems.
Rowridge transmits at a lower power on horizontal for some channels. I’d imagine the aerial needs to be vertical and that’s if it’s pointed to Rowridge and not catching some of the repeaters or Midhurst which is closer.
Presumably it cut off again on last Sunday’s Top Gear, Martin’s already asked, but were you recording anything else at the same time or immediately after? i.e what?

Are you saying Rowridge transmits some multiplexes horizontally polarised and some vertically polarised? If so what is the reason for that? Normally main transmitters transmit horizontally polarised and relay transmitters vertically polarised.

Interesting. Could it be French interference? The map at http://www.aerialsandtv.com/rowridgetx.html shows the nearest French transmitters. May be out of date.

I think it’s interesting reading for those on Rowridge and in that area along with my earlier post #27:

We can all 2nd guess as much as we like; however the OP Steve is the only one with the relevant information. I can’t imagine all his neighbours suffering and remaining quiet. I don’t think we’ve established much so far, not even if there are or would be duplicates in the 800 range or if there are multiple recordings going on. I don’t even think we know for sure which transmitter is being pointed at be it horizontal or vertical. Personally I’d be cross checking channels and Muxes against what they should be as well as double checking a few other things.
I’m tempted to suggest that Steve ring round a few aerial installers who have local knowledge

Interesting stuff and may explain the wildly varying signal strength Steve983 is reporting, I’d move.
The late starts early finishes though I’m not so sure about. It is well known that the 9150, 9200 and 9300 machines suffer from a delay after the running status change has signalled a recording to start using Accurate-Recording. Myself and a forum member on DigitalSpy did a lot of testing on this delay a few years ago. From our results it was apparent that if a programme started after its scheduled time the delay was in the order of 5 or 6 seconds or less, if the programme started before its scheduled time the delay could be, and usually was, up to a minute. The running status change also signals the end of a recording, interestingly the 9xx0 machines show no delay in stopping a recording. Our tests were done on Emmerdale and Coronation Street because of their frequent episodes so were restricted to ITV1 but nevertheless showed the workings of the 9xx0 machines and the results seemed to be consistent with other channels. I have noticed in the last couple of years that the running status change occurs a few seconds earlier than it did when we were testing, at least for ITV1.
Ok, as requested:
I’ve just run a new auto search = No 800 channels
Also just run another manual search = No 800 channels
(Now waiting for EPG to populate again!)
The codes and frequencies are all confirmed by Digi UK as correct although no channels found on 21 & 31.
My aerial is pointing at Rowridge, no signals found if I try to search for Midhurst transmitter.
My immediate neighbour doesn’t even record anything so not much help there.
I will get in touch with an aerial installer, the last one I spoke to wasn’t very helpful, I’ll report back when I can.
PS. EPG has come back quickly this time!

But are they experiencing the wildly varying signal strength that cause you channels to come and go? Is their aerial pointing in the same direction and oriented (elements horizontal or vertical) the same as yours?

thanks for confirming that. 21 and 31 are HD as far as I know. Also thanks to Luke for explaining the EPG population, I only know that every now and again I’ll have a mux missing in the EPG and selecting a channel from that mux whilst still in the EPG populates it pretty quickly.
What was the reasoning behind for doing a manual search after the auto tune?
Have you done a factory reset ‘default setting’ and let it auto tune? and then used it?
In answer to more questions above.
-All my neighbours have their aerials pointing in the same direction as me ie: Rowridge. As you might know that transmitter is on the Isle Of Wight, there is a clear line of site, you can see the IOW from the seafront half a mile away.
-Not sure if neighbours have been experiencing problems, I have always assumed (maybe wrongly, that my 9300 was a fault).
– I did a manual search after the auto one just because I thought the manual one seems to work better (hard to tell for sure)
– Yes, I did the factory reset and autotune, will have to wait and see how it behaves now.
Thanks to everyone for their input, I will consult an aerial installer to see what he suggests and report back.
thanks for the update Steve,
it may seem like we’re asking questions for the sake of it, not true by the way.
One thing I’m still unsure about is horizontal or vertical aerial?
Rowridge transmits on a lower power horizontally for some channels, it may just be a case of turning the aerial to a vertical postition to get a better/stronger signal.
Is the aerial H or V and how does this compare to others locally.

In your post #21 you say you have the same problem when using your TV tuner so it’s unlikely to be the 9300 at fault. To eliminate the 9300 completely plug the aerial lead directly into the TV, if you’ve still got unreliable channels then the problem must be with the aerial system or something peculiar at you specific location.

Well yes its true I lose eg Sky News & Dave from my tv tuner too but I never experience any problems watching the tv tuner live on the other channels. These above mentioned channels together with Film4 seems to be the ones with the most variable signal as confirmed by the chap at Digital UK. It seems that when the signal is weaker I get the skipping & jumping (on playback) on Film 4, this ties in with what I’ve been told by someone before that its ok to watch a weak signal but more tricky to record it. Anyway, you may be right in that a new aerial is what is needed.
Looking around at the other aerials in my road, they are horizontally pointing at (mostly) Rowridge, however I did just spot a couple on top of flats (higher up than me, I’m in a bungalow) that would appear to be pointing at Midhurst.

Sorry but the skipping on Film4 (and various other channels/programs) on replay is a characteristic of the 9300 that no aerial in the world will help you with. Humax have been aware of the problem for some years but I think we can now assume they do not intend to fix it. The specific problem only affects the 9150/9300.
I wasn’t aware of Film4 skipping on the 9150/9300’s, but I bow to Martin’s expertise.
Personally I’d turn the aerial to vertical as a fair amount of channels are broadcast with more power on vertical and this should solve Dave/Sky-news etc., but that’s easy to say at a distance.
I’m guessing there are three problems,
Horizontal or vertical – which your local experienced aerial installer should know about.
Film4 appears to skip anyway.
Multiple recordings on a Sunday affecting Top Gear and not so many scheduled for the Monday repeat, although multiple transmitters will also affect this or timings as Biggles pointed out.
Personally, I’d turn the aerial to a vertical position first, but you’re best placed to decide
