After retuning I can only get channels 46 and 47. How do I get the rest please?

Same as Adam, retuned after the latest switchover and can only get BBC channels. Is there a problem?

OK you may say I'm on my High Horse again, tuned my Freesat box to Glasgow postcode to see the local BBC and STV news of the Black Hill switchover. On Tuesday's run up to switchover, nothing on either and on Wednesday's local news nothing on the BBC but STV gave about 2 mins to the subject. I know I've said it before, down here in the West, South West, South Wales area switchovers of Mendip, Stockland Hill and Wenvoe there was a lot of coverage on the local news.

Steve: Have a look at

hope the link is okay. My use of the word 'permanent' may be going too far, but that seems to be the way Alba has been implemented.

Hi , I have retuned my mums TV in yesterday and have all the channels (I think) with the exception of Dave & Dave Ja Vu (were previously 19 & 25 (?) (I think) on her humax freeview+ box. Do I need to unplug everything including the ariel and do a factory reset ? I have just done a automatic rescan through the box.

Postcode is G15 and signal strength is maximum os why not these two channels when she gets all the others

Any help much appreciated

Since DSO started, I've been having intermittent pixalation/herringbone pattern to portions of the picture, and audio tearing. About once every 5 minutes. Although I am in Craigkelly area, my box locks on to Ch46 on BBC1 Muxes seem to match Blackhill. Checked all channels present, I have a wideband aerial (I think it's group E),attached to Pioneer DBR-TF100 Freeview box. Box functions are all fine, checked connections, done full reset and factory reset, but still getting issues. BBC 1 ch 46, Signal strength 88% Signal quality 100%

MM: Its always best to carry out a complete re-scan in these situations, this done by a factory reset as you have mentioned, or simply by carrying out the first scan with the aerial disconnected, this killing anything stored in the programme memory, then once done reconnect and give the box a further scan thereby loading all channels available into the memory again.

LF: If the aerial points to Craigkelly but it decides to tune into Black Hill, it probably indicates that the Craigkelly signals are too distorted to use. You should expect to get very high signal levels anyway - if you have any amplifiers or boosters, you should remove them. That might still leave you with too much signal, in which case you should add an attenuator.

Older boxes were often calibrated to the maximum possible signal from one multiplex - maximum safe levels (avoiding distortion) are often way below 100%. On my Humax box it's actually about 50%. I can't find a spec for the input range on your Pioneer box.

Thanks Mike,

I did do a factory reset (I didn't unplug the aerial though) - I think you're right about Craigkelly, if I manually tune BBC1 to Channel 27, the signal strength is equal to that of ch46 (85%) but there is no picture being pulled in.

I don't have any boosters etc on my aerial, I did try a 6db in-line attenuator, but in made no difference. Interesting what you say about calibration of boxes ie max safe levels of signal - I'll see if I can find out about my box. I will see if I can plug in a different box.
