Phil:

Hutton, being a relay, is very unlikely tpo have its power output changed.

Do you have a wideband aerial in use? If not you need to have one fitted. That is likely to be the cause of your problems.

Phil: According to Digital UK, the Hutton relay is changing frequencies and increasing power output on 19th June. You will likely need a new aerial (if your existing one isn't wideband) as the transmitter is changing from Group C/D to Group A frequencies. This should be available free of charge if you don't have satellite or cable.

1pm on 12th June, and a scan is showing nothing on ch36 594000 (com7 HD) again.
All the websites are reporting 100% signal/no problems.
Hopefully after the next retune it will settle down.

Since the recent update at the Mendip transmitter, we have a reduced signal quality. Resulting in the picture pixating and sound quality poor. My post code is NP26 5RN.

Have you had your aerial changed for a wideband type? If not, you need to have one fitted as several channl;es have changed frequency and there are nore changes expected next week.

Gerald Kington:

On the 19th June the COM 7 programmes are moved from channel 36 to channel 55. That is one further reason to use a wideband aerial else it will not receive all the available channels.

Andy:

No one else has reported such a problem. I use Mendip in Trowbridge and do not have any such problem. So please check all you aerial cables for damage and check the coaxial plugs/sockets, unpli=ugging them and refitting to clear any possible oxidation on the contacts.

Phil:

If you are receiving PSB1 on UHF32 then you aren't receiving the Hutton Relay as it doesn't/& won't be using UHF32. You must be picking up a weak signal from Mendip. I'd suggest you do a Reset & then a manual tune for the Hutton UHF channels (59,50,55) and as already pointed out noting that they change on the 19th to 21,24 & 27.
