Iain Davies: There has been no announcement yet of any date for any channels to switch to HD only output, or for any further multiplexes to switch to broadcasting in DVB-T2. Although the BBC have said they intend to switch to HD only broadcasting in the future.

My reception in Bath (BA1) has been terrible for the last year or so. Quality interrmittent, some channels I cant receive at all some days and hardly ever able to get HD channels. I'm high up, have had 2 ariel firms in, have new high gain ariel and have replaced ariel distribution amp but to little avail. Have a number of different makes of high end TVs and PVRs - Humax seems to be the worst! When engineers have measured the signal strength it seems to be good but they do warn that there's a fairly narrow acceptability band for digital and too strong a signal can be as bad as too little!

Dave:
Would you please give us both a full post code and the signal strength readings for several channels. Then we may get some ideas on how to proceed and p[otentially resolve the issues.

Jane crabb: Unless you've changed the RF output channel on your Sky box, it will still be using C48, however as C48 is used by Mendip for the SDN multiplex (which is predicted to have variable reception at your location) it would be a good idea to change it (C38 is usually a good choice as it isn't used by any UK transmitter). You'll then need to retune the analogue channel on your second TV to match the one set on the Sky box. See the link below for a guide to change the RF output channel on your Sky box.
How do I change the RF output channel on a Sky Digibox?
