Many thanks for coming in for my problem.
I have done the manual tuning and on 24 I get about 2 on the quality and 0 on strength. Pulling the aerial cable out so that it touches the socket off centre the quality dropped to 0.
I did check on 27 the commercial channel that I am receiving and got quality of 2 and strength of 2, on both 57 and 61 I got 0 but of course the aerial is pointing in the wrong direction.
Prior to the "improvement" following the switchover I think I was getting between 7 & 9 for most channels.

Freeview mainly OK, but channel 33 shows poor signal quality, constantly varying - all other channels show 100%.
Do I need a newer aerial , or change to vertical or what?

Keith Smith: The Commercial multiplexes (which includes the on currently on C33) are on low power until 18th April when you will have to retune.
You may or may not need to switch your aerial to veritcal after that date.
Rowridge's transmission power for the Public Service channels is 200kW horizontally and vertically (and that is the case now). The Commercials will be 50kW horizontally and 200kW vertically. Therefore if reception issues are experienced with any of the Commercials, changing the aerial to vertical may help.

David Brinkman: Pleased to hear that you have sorted the "mystery" out insomuch that the problem was caused by the actual aerial amps themselves being overloaded. I would though be obliged if could let me know the brand of the devices involved, this to enable me to check on the circuitry / transistor type used in them.
