peter parker: Is that a daily problem with C60 or one which became apparent today? If the latter the tropospheric ducting forecast for midday today shows a fair chance of ducting in Suffolk, which could result in interference from out of area transmissions. Conditions should return to normal later today.

Dave, Nick has another problem. He goes away a few days, returns and finds his box has lost all the BBC channels but none of the others and has to retune. Please, any ideas?

OK, Dave, sense of humour appreciated. Only the BBC channels disappear.

Nick: When you say that you find you have lost all of the BBC channels, are you meaning that although they are still seen listed in the EPG listings when one is selected it results in a blank screen, or is it the case that they have disappeared from the EPG listings?

JB, when I press channel one, it says '1,' but is blank.
I am also puzzled by the fact that I am currently not getting pixellation, or something similar, ie a few small 'boxes' briefly dotting the screen now and then on the two strongest muxes, ITV and BBC. If you recall it was suggested this paterning could be the effect of too large a signal since erecting an almighty aerial, at height, with 28 db booster, to pull in the naff mux on c60

Nick: In that case you should use the manual tuning procedure on mux Ch44 (BBC1) but NOT pressing search or scan after having entered the channel number, because if the signal is actually weak it will generally be indicated as such accompanied by varying quality, whereas if the signal is over the top then its liable to indicate 100% strength but with zero quality.

At least thats whats indicated on most devices when operating in these type of situations, although not guaranteed to be applicable in every case as its dependant on the equipment being used.

JB,
if I was using the Icecrypt box this would be useful, but I am using the pvr, Tvonics which does not have signal strength/quality bars, just sig qual which always says 'very good,' and sig level where the bar is always solid green.
Would you have any idea why periodically I lose these channels on the tuner? I switch the box off at the mains at night, but only the BBC channels, and occasionally the ITV channels disappear.

Nick: TVonics is one of these brands that does lend itself to being used for experiments, and in your type of situation this is a must!

However with reference to your query, what is the model number of your PVR, and if it only has auto-tuning and not manual as well, then during an auto-tune can you see the names of the programmes being picked up? or if not then does it show a progress bar during the scan? as there is a test I would like you to try but this is dependant on the answers to the aforementioned questions.
