Missing channels

[tony sayer]

That wasn't directed your way that much....

Effing "Dave" has gone away, now. I tried removing the active splitter and substituting a passive one and retuning (using the right menu option this time), but channels 19 and 20 are still missing.

This digital telly is pants.

It used to work OK here. However the " digital" switchover has resulted in a secondary transmitter increasing its power. Now retuning the TV has resulted in several hundred channels and I have had to switch in the "soft" attenuator in the TV and eliminate duplicate channels in a mass editing session.

In the loft and directly at Sandy Heath, assuming I can take a compass bearing correctly.

No, there's a splitter which provides a feed to the kitchen, then a VCR, then PVR, then the telly. I suppose I could take the VCR out of line now, since it's only used to play VHS cassettes now (of which we have many hundreds)

So far I've only noticed 19 and 20. I haven't checked this morning, nor on the completely separate bedroom telly. I couldn't be arsed. I watched "Lost Christmas" with Eddy Izzard, which I recorded last Christmas, instead. And very good it was, too.

Dint know you were in this area,

Sandy heath is due for a retune in a week - May 9th - so anything we tell you now will be obsolete anyway.

All MUXES will be at 170/180KW then so you should get good reception.

In general either you get a whole mux - 10-25 channels or no mux at all. You should have around 105-120 channels available.

Some channels are blank as the content suppliers fiddle around.

No problem, 8 to 10 miles as the crow goes, the waves sometimes fly on alternative paths tho;)..

Correct and only one really..

;)..

Run it straight off the aerial and do a retune if you can. I very much doubt that at that range its too strong especially with a loft aerial and NO amplifiers in line, and I very much doubt there'll be any other transmitters you're picking up there..

As above straight to the aerial and re tune but do bear in mind theres another sandy retoon before long 9th May IIRC!...

I recommend posting on uk.tech.digital-tv for problems with digital television. You'll certainly get answers to your question about the power being turned up after switchover [it usually is] and whether or not a digital signal can be too strong [it can be].

Sorted (again). Retuning worked fine with the TV plugged in on its own, so instead of running the aerial feed thusly;

Antenna -> Active Splitter -> VCR -> PVR -> TV | V To Kitchen

I've changed it to;

Antenna -> Active splitter -> Passive splitter -> TV | | V V To kitchen PVR

I think I'll get a 3 way passive splitter to replace the two splitters.

Except that Dave doesn't work in the kitchen.

I effing give up.

At least until the retune on May 9th.

The exception to that rule which I discovered was when the co-ax is old and soggy... I had one section that I reused when I moved in, that I had to replace in the end. It seemed to have the surprising knack of dropping one or two channels from a mux and leaving the other undamaged!
