John without looking into it,maybe your getting a relay,that has not switched yet,it will have done by mid afternoon I understand.
So try a re-scan,a little later.

cheers dennis, that could be it, as we are serviced by kidderminster which i believe is a relay from sutton.

I live in North Wales, nr Llangollen, and today for the first time I have been able to get ITV4 & Yesterday (Sutton Coldfield). However, this is only on one out of 5 TVs/digital boxes.
It looks they are not capable of the sub frequencies (eg 618.2MHz). Certainly when scanning they show 618.00MHz, 619.00MHz, etc. I can't manually enter a frequency.
Does that sound a likely cause?

SteveL: All Freeview boxes can deal with the +/- 166kHz offsets, but most do not show them. I can't say more about your reception without a full postcode.

Billy: Yes, there is a whole page about that at Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice .

christina: C21 is the lowest broadcast channel in the UK, and C68 is the highest, your box will scan between C21 and C68.
These are *NOT* the "local channel numbers" such as 1 for BBC One.

Brian my friend, risk getting all technical, as I do believe it or not, not know everything, lol, unless read and learned etc, or shown, which I prefer to be honest, anyway, question:
I've read, but hard finding much info in google, always subject to what you type in, but with Lark Stokes Commercial channels going on the 40's how much lose would that be, so for argument sake:
channel 21 with a gain of 21db will on channel 41 have only 20 db.
I know Aerials compensate for this, but remember I'm keen once I move it into the loft next Wed all being well, to use my new Log Periodic, with only 7.5 db gain and 25 max variable amp.
I know you likely will say not that simple, also tried to find comparison with the db/uv or whatever it is, to the db gain, so for example:
60 db/uv equals 21 db gain
Thanks.

LOL, sorry, that's me for you.
Err not sure how to explain, as frequencies go higher, I'm away they have more loss, hence CB rig at 27 mhz, great conditions on 4 watts can go miles and miles, base station to base station up high can cover, gosh, 20 or 30 miles, who knows.
But TV at that, LOL, no way, so they transmit often at hundreds or thousands of watts, why, because as the frequency climbs it loses more.
Thing is, we see TV Aerial compensate for this:
Gain (curves), Again
However, if you have a log periodic aerial, they are pretty much flat.
Just because I'm getting channels 23 and 26 at 80 to 100% does not assume I'll get channel 47 from Lark Stoke.
So my question is, do you know of a loss factor, again for example:
Channel 21 at say 20db
channel 41 would be at 18 db
channel 61 at 16 db.
Meaning I'd need 2 db more again on an amp to get the same as I did on channels 23.
I hope that helps.
Also on the other, some talk in, as on my useless meter I bought db/uv, looks like a u, likely not, says 60 poor 70 and 80 okay and the last light 90 Excellent, measures in db/uv so 60 to 80, say 45 to 50 min level for Digital.
But when we talk about Amps, it is mostly in 15 to 25 db gain.
Was one site gave me an idea, showing both, but not 100% sure that means, you know, like some table.
All confusing I know, cause depends on circumstances, aerial in or out, how close you are to a transmitter, and what height aerial and obstacles and Amplifier and oh gosh, you know..... (CV59HG)

Actually, found this again:
Field Strength Calculator
So it shows 110 (dBuV) at 47 but 113 at channel 23, so nothing in it and way high, but as it states, take about 10 to 20 off:
Note that your results will be of the order of 10-20dB lower than this predicts. To get the signal strength predicted by this calculator your antenna must be several metres higher than surrounding obstructions, house roofs etc and have a clear line of sight to the transmitter. Most domestic installations do not satisfy these requirements, hence assume at least 10dB lower signal levels.
I still think I'll be more than okay and shall see in weeks time.
Thanks anyway Brian, ignore me again, crack on helping others with the change over issues. (CV59HG)
