Hello
I have just set up a Freeview box (BUSH 50 quid Makro special) and am having a slight problem with it. Apologies if these questions have been answered a million times, feel free to point me to an FAQ. I tried the box with the existing rooftop aerial and could get a few channels, Freeview website says I will probably need a new aerial. Fair enough, I get and install a 19 element Wideband aerial and the analog TV signal is as close to perfection as I have seen. I plug in the Freeview box and retune, now I can get all channels except the ones sitting on MUX 1 16 QAM (BBC 1, 2, etc) - they don't appear at all in the channel list. Would there be a realistic chance of sorting this out by fiddling with the aerial, buying a signal booster etc, or am I just out of luck with these channels?

Would there be a realistic chance of sorting this out by fiddling with the aerial, buying a signal booster etc, or am I just out of luck with these channels? You'll probably find a lot of useful help here, but first we need to know a: where *you* are, I'm in Warsash, near Southampton. b: which transmitter you are receiving from (or at least, which direction your aerial is pointing) Um. Not really sure, I think the aerial is pointing south east. c: what is the state of the cable from the aerial (i.e. did you replace that at the same time as the aerial?) I replaced it with shiny new cable as the old one was corroded and full of water. and d: anything else you might think relevant :-) For example, is the DTT box the first thing into which the aerial is plugged? If it is not the first thing, is it possible that (say) your video's output channel is the same as that of the BBC multiplex? I ran the cable straight from the aerial into the box, so there is nothing in the way. It's a very bog standard setup as far as I can see. I don't claim to know a lot, but if you are receiving *all* the other channels ok (in particular ITV, C4 and C5) then I would have thought it was highly unusual not to be able to receive the BBC channels. Older boxes have two "retuning" options. In a situation such as yours, if you had an older box I would suggest using the "store channels" menu option rather than "add channels", but I don't know if that is relevant for your setup. The manual for the box is less than exhaustive, it just says to do automatic tuning which I did. ITV1, 2, C4 and C5 all seem to work fine (although I did get a slight picture breakup on ITV1) as do the others it has picked up. Thanks for your help. -- Mike Jenkins Dreamcast / Gamecube FAQs - http://www.washu.clara.net Private replies to: Mike's Auctions: http://makeashorterlink.com/?W49D31BA1 |

Your aerial is probably pointing at Rowbridge (13 miles south of you).
From Rowbridge BBC mux 1 is on channel 23 and BBC2 analogue is on channel 24 (the itv mux is on channel 52). So if you receive BBC2 analogue well you should be really be receiving BBC mux 1 okay. Interfernce from elsewhere could be the problem. You could try pointing your aerial in a different direction see link below for a list of transmitters in your vicinity and their directions from Warsash. http://www.wolfbane.com/cgi-bin/tvd....=L&OS=SU495061 JGG (Mike Jenkins) wrote in message news:1fy00ow.je59oq1cezo1sN%mikejenkins_uk@hotmai l.com...

How close are you to the transmitter ? your digital box actually needs a lower gain signal than the analogue tv/video but it needs good recption free from interference and reflected signals. In my area 14 miles from a powerful transmitter I can actually get digital on an indoor aerial. The obvious things apply -- a dodgey aerial flylead, dopwn lead or socket can throw a spanner in the works. If your aerial flylead runs through the VCR before going to the digi box try running it straight from the outlet to the digi box, if that dosen't work as a test try borrowing an indoor aerial -- if either of these work you could try using an in-line attenuator (as sold by Maplin). On the otherhand if you have a weak signal try a cheap aerial booster, the Slx2 as sold by my local ASDS for arond 7 quid isn't bad as these things go. Would there be a realistic chance of sorting this out by fiddling with the aerial, buying a signal booster etc, or am I just out of luck with these channels? Thanks -- Mike Jenkins |
