Stephen my question also.

jb38 I have a signal strength meter do I just plug it in the aerial input or output.

My unit is Thompson recording system. The problem also occurs on another set with a built in decoder.

On first change over to digital from Rowridge transmitter every thing was fine and all channels had high signal strength.
For the last three days I have had low or no signal for five channels. Retuning does not pick up the channels or picks them up with low signal strength. A broken up picture appears and the the screen goes blank with a heading " Channel not tuned.
Digital UK tell me the reason is due to work being carried out on the transmitter and they only get progress reports once a week they do not know when the work will be completed. They also advise not to retune whilst the work is being carried out for fear of losing channels.
How will we know when it is safe to retune ?

John Cook: The answer to your question is that you won't which is why they advised you not to retune!

You started off with one problem; picture break-up or no signal. Now you have two potential problems: picture break-up/no signal and the set not being tuned.

Digital UK publishes engineering works at www.digitaluk.co.uk/engineeringworks

Rowridge digital TV is currently "liable to interruption".

If you have a manual tune option, then try using it. Refer to the Rowridge page for details of UHF channel numbers.

I have recently lost the entire C62 (802.0MHz) multiplex on the Oxford transmitter (from Friday 20th April).

That means ITV3, ITV2+1, 5*, 5USA, Quest, The Zone, Channel5+1, CITV (plus others) are all showing NO or BAD SIGNAL.

They are still down today (Monday 23rd April).

"Well, I'm 11 miles due west of the Oxford transmitter and reception has been fine on all multiplexes today."

Yes, it is a strange situation. Although I get "NO or BAD SIGNAL" on all C62 (COM4) Channels from Oxford, my Signal Strength is shown as normal on these Channels (~85%) but Quality is zero.

Since my re-boot, I have lost my EPG on those Channels, too. Re-booting and re-tuning have not restored C62 (COM4) from Oxford.

However, I have a second digi-box, and that is OK on ALL Multiplexes.

On the basis of that, I considered my first digi-box to have developed a fault, although gawd alone know what!

It was searching here, and seeing Stephen AND Robert's reports of similar problems at similar times with this Multiplex from Oxford, made me post.

A good signal strength with bad or no reception sounds very like the effect of an interfering signal .This could be a local radio transmitter.Not nessearily on ch62 (image interference) .Some boxes may suffer this more than others. Or a tv station on the same channel from a nearby region.

Isn't it interesting that different people experience the same problem, but we are told not to re-tune etc. Well sorry, how do we put things right, when the problem seems beyond our control.

I was getting an absolutely excellent signal on Channel 62 at 9.10pm last night. I was watching channel 10 (ITV3) turned it to 31 (Fiver US I think, and black screen and no aerial signal. Checked Channel 30 exactly the same, so went back to Channel 10, that too then had the same problem.

I decided to use another digi box, which seemed to work fine, so tonight I will again be looking at around 9 to see what happens. I know electronic equipment can have intermittent issues but I never known it to be scheduled intermittent.
