Dave: Sandy Heath was off air overnight for engineering work to carry out a frequency change. You will need to retune again now that it is back on air (retuning when you suddenly loose signal is the worst thing to do and will never fix anything).

Sandy Heath TX, ref above post from StevensOnln1, just got off the phone to Freeview re loss of Com 7 & 8 after retune this morning. They were unable to help. I have no signal on CH 55/56. All other Coms fine. Can anyone advise?
Thanks

Mark: Have you checked for any loose or damaged cables or connections? Please provide a full postcode so that we can see where you are in relation to the transmitter and your predicted signal strength etc.

Thanks Steven,
Yes, I checked all connections. Surely it would not selectively fail to receive on 2 whole Coms only? The DVB tuner in the TV is missing all channels from Com 7 and 8 also (non HD) so it's not my HD box or connections. Postcode is SG8 5PP.
Thanks

MikeP:
com7/8 are still shown on channel 32/34 according to ukfree Sandy Heath table - which does not mention c55/c56, so that makes thing confusing too

Thanks MikeP for your reply and information.
Re-tuned around 8.00 ish last night and now have Com 7 & 8 on ch55 and 56. Signal condition check shows intermittent bit errors, Strength 8 and Quality 3. (before the switch it was 10/10). I'll now look at a better gain aerial.
