I live in a block of flats,most of the tenants are over 60. The flats are managed by Bournville Village Trust tel:0121 472 3831 they are insistant the commual ariel is set correctly for the switchover,this I very much doubt,my post code is B30 1ST We have lost channel ITV 3&4 History CH all shopping Channels all 900-910 Sky News Pick TV & various others.Please can you communicate with BVT Thanks in antisipation of your help.

Confirmed top up box with a mind of it's own, ARE OTHERS the same, WARNING:
It is the T215 one you can get from argos.

AS those who read my posts know, I'm now on Sutton, may try Lark Stoke tomorrow.

Anyway, in the loft on log periodic and lowered the gain slightly now, so might be around 15 db on amp, but here is the massive problem.

I did a factory reset again, few times since had the box in last few weeks now, and with aerial connection pulled out, skipped through the lower channels.

Now knowing it will not work, unless I least get one mux in, I put back in and collected channel, think it was 46, Sutton.

All was well that night as I manually put in the rest.
But signals vary sometimes, up and down like mad, though often not affecting the picture, surprisingly, sometimes it does.

But next day, put on, and swear still had it on, then bang, later noticed, or next day, but was later on, watching BB on channel 5, that I'm back on Allesley Park again.

I am seriously wondering if mine and many other makes of set top boxes are auto tuning themselves to stronger transmitters if they can get them.

Who knows, most puzzling and annoying in some ways, 100 over 100%, and perfect, works, no glitching, but mad, okay both in same direction, but Allesley Vertical and Sutton Horizontal, likely the Amp.

This may explain why so many claim, I had the channels, next time switched on, or next day, they gone, seems the boxes ability to retain, even manually puts in muxes is dire, if it senses, picks up another in same direction.
Given the crossovers now, power boosts on transmitters and fact many still have hi gain aerials and amps on, might be what is happening.
:(.

Billy: I've seen both digiboxes and DTVs develop a fault whereby a reset and rescan for channels appears to put everything in as you'd expect.
This situation lasts only until you put the box (or TV) into standby and then switch back on again. For no good reason, some channels may now be "missing", or have "recovered" their previous tuning criteria.
If you suspect your kit, its worth scanning with no aerial connected after a factory reset to confirm that at the end of the scan no channels are found. Then switch off (leave a few seconds) and then switch on again - there should still be no channels. Any box or TV that comes back on to a channel (or shows e.g. BBC1, possibly with a blank screen) isn't working right.
I think this is a fault with memory chip(s), but haven't confirmed.

Aerialman:

We've had excellent reception both standard and HD since doing a full rescan on the 21st. Loft mounted aerial.

Interestingly, I've bought a cheap USB freeview dongle for my laptop with a 15cm whip type aerial and I can even get 30+ Freeview channels on that with the aerial indoors (works much better with the magnetic base on a steel plate for reasons I'm sure someone can explain).

B28 8EF should however be a fairly strong signal area.

Thanks Jim, all seems fine now on Lark Stoke, though usual pixel break up, pity channel I want, whether Sutton or Lark Stoke, always on the weakest Mux, go figure.

Keith let me check my last signal takings in the loft on this transmitter:

YUP, how interesting that best channels were 43 and 46, with 95% Signal strength over 100 Quality.
39, one I wanted most, was 80% SS over 100 as are the rest.

Who knows why.
Now on Lark Stoke and even changing to a different amplifier, 23 db gain, still as on sutton get the odd glitch, more a pixel break up and then okay again, but not too often looks like something going to have to live with, cause not buying yet another aerial, got more cable today, throwing more money away and not getting any better really.

Who knows why, unless, and without a recent picture of it, Sutton has them at different heights, meaning channels 43 and 46 are higher at the top, while others are lower down, or the radiating pattern, though one would suspect, it will be all around.
My sympathies as I know all to well, though I enjoy tinkering at times, the annoyance of this darn medium, satellite beats it hands down.

Satellite, (freesat) oh gosh, maybe one glitch in a few hours, rain and I mean VERY heavy rain, lose some channels perhaps.
Freeview, oh gosh, glitch, sound going, playing up, pixel break up, every few minutes if not much less.

But I refuse to give Sky my money and so have no alternative, cheapest option but to have freeview for top up tv nonsense.

Stuart O.: A signal overload will cause no damage, just loss of service. The set-top box will implement an "internal fuse" if high signal levels are detected to protect itself.

Stuart O.: The voltages we're talking about are very low. The recommended signal level for analogue was 60 to 80 dBuV - which is 1 millivolt to 10 millivolts. The normal level for the signal on a cable from another piece of equipment, such as SCART, is 1 volt peak-to-peak, 50 to 500 times the size of the signal arriving at the TV.

The problem is that most boosters are simply one transistor, as is the mixer circuit in the tuner. (The mixer downconverts from the frequency arriving on the aerial to a much lower intermediate frequency; it does this by controlling the gain of an amplifier with a local oscillator circuit, that outputs a pure tone at the tuned frequency.) Digital TV requires that any amplification is linear. A transistor's transfer curve is actually exponential - Bipolar Transistor - Characteristic Curves , second diagram down - but if you use a small enough region of it, it's approximately enough linear. If the input is too large, the range of the curve covered becomes larger and it's no longer linear.

For analogue transmissions this didn't actually matter too much - it was noticeable if you knew what to look for, but the transmissions were spaced far enough apart that it didn't really matter. For digital it causes problems both within one multiplex and for adjacent multiplexes - it's a problem called intermodulation.

At extreme high levels it can cause clipping as the amplified signal reaches the upper supply voltage - the maximum that the transistor can switch - or the ground voltage - no current flowing at all. Neither of these cause damage either, and you would notice intermodulation long before clipping was a problem.

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
