Poor Signal Strength on ch42

Better antenna or alignment.

Gavin - is it strength or quality or both? Strength as said above is antenna alignment problems. Quality is interference - and short of possibly using a higher gain antenna there might not be much you can do

Without checking, it's quality.

As it's doing a re-tune all of the other stations come in at 10 but channel 42 is at 6.  The antenna was installed four years ago and shouldn't be a problem.

Is this channel coming from a different transmitter? Is that why it's different from the rest?

Not familiar with the Panasonic but my Humax needs to be tuned manually to pick up the right version of each station. If you go here http://www.digitaluk.co.uk/cov...cker/manual_retuning

You check which channels you should use. Hope that helps.

This doesn't make sense,  ch42 is in the middle of aerial group B.

Unless its a quirk with the HDD tuner.  

Whatever I expect you will (eventually) need the help of an aerial installer.

RE a new aerial 4 years ago,  that doesn't mean its now correct.  The last of the realignments changes took place in Dec 2012 to enable space for G4.  

Where do you live (nearest town) & I will look to see what channels & aerial group you should be on.

OK,  I see you are Kingsbury, N.Warks. 

Your TX is Sutton Coldfield located at Hill Hook, this transmits all its six MUX's at 200kW making it the (equal) most powerful transmitter in the UK.  Its only a few miles from you & a piece of damp string would be an OK aerial.  

Sutton Coldfield is on aerial group B & it needs to be horizontally polarised.

Throughout the various realignments, Sutton Coldfield has always been around group B, the last major change was in Sept 2011 that fixed the frequencies where they are now. ch33 was added in Dec 2013 & although 33 is outside group B its close enough to be OK, especially at that distance.

I think its a pretty sure fire bet that your aerial is group B, assuming it was installed by a pro-installer.

I don't see how its an aerial problem as the other channels will be off as well.  

I would suspect its the HDD tuner

We had a notice arrive regarding terrestrial TV reception of some channels and the arrival of a 4G mobile phone signal, has a 4G service just arrived in your area.

Thanks, everyone!

Lunicycle - the link still shows ITV3 on channel 42 so I don't think that will help - but that's what I was looking for as a potential problem.

Derek - well I do get a good signal for EE 4G at home, but I couldn't say whether the arrival coincided with any change to the signal quality.  Wouldn't it affect more than one 'channel'?

Mike - I'm tending to agree with you - it's probably the HDD tuner.  We used to have an equivalent Pana TV and could have compared the signal qualities (as they had very similar tuning routines). That's now with my sister-in-law (who should be on the same transmitter) so I'll have to check.  I haven't quite figured out where to find the same info on our recent Sony TV. I might be forced to watch an evening of ITV3 to test it out!  

I thought the same when I chirped in yesterday as I had the same letter.

In Gavin's case, he (Sutton Coldfield) would not be affected.    G4 took over the old TV channels from ch62 to 68 (800MHz).   That's at the top end of the UHF TV frequencies & (might) affect those with aerial group C/D & the highest frequency channels from ch58.   Sutton Coldfield's highest channel number is 46. 

Just wondering, given your location and the distance to the Sutton Coldfield Tx, whether you've got too much signal and are overloading the tuner head in the Pany HDD (you mention quality is lower on CH42 but signal strength is fine). Worth trying an attenuator between the down lead and the box. You can pick up a 3dB one from Maplin for a few quid.
