David: Unfortunately the manual that I have for the TH-42PX60U is for the European "E" version and not "U", which I believe to be very similar in most respects and which does have a manual tuning facility, this accessed by pressing "menu", then in the three choices seen in the "main menu" box select "setup menu", then scroll down the set up menu to "tuning" and click "access", manual tuning seen 3rd down the list, if available on the "U" model that is.

However, if you do not see what's been described mentioned in the menu then I suggest that if at all possible the best policy is to borrow another TV and try what Dave Lindsay has suggested as it should have worked, as although you may not have had any success when you tried this with the Panasonic it could be simply due to the type of tuner used in the set, and its not necessarily the case that the procedure would not work on another brand with a tuner not quite so prone to being desensitised by the presence of high powered signals on its input.

If though any other TV you might manage to borrow doesn't work either, then I cant see much chance of success except by the inclusion of a group C/D filter in line with the TV's aerial socket, as this will attenuate the lower 23-29 range used by to a level that might allow the TV's tuner to pick up Mendips channels from Ch48 upwards, the upper range changing on March 28th as well as in 2013, but with Ch48 always being the lowest channel used.

By the way should you manage to borrow a TV and it had a manual tuning facility then have a try at manually tuning it, Mendips muxes being: 61 - 54 - 58(HD) - 48 - 67 - 52.

Another final point being that its assumed that your aerial is horizontally mounted and with a 272 degree heading towards ?

I have heard there are some more coming up on either at the end of March or in April. Next year there are yet more changes to come with the high powered BBC Mux having to move away from ch61 to make way for the new 4G mobile phone .

Richard: Simply because Mendips ArqA mux is changing its operating from 67 to 56 as well as powering up from 12.5Kw to 100Kw.

What about ArqB on 52 ? Is that getting a boost from 12.5 KW to 100 KW at the same time ?

Hi

I think - The main entry for the MUX above is correct but the After 7th April is wrong for ARQA and ARQB.

Cheers.
