    Nothing coming through on Channel 51 from Wenvoe, even though I am about 25 miles away, I should get a signal when the tests do start. I live on top of a hill about half a mile from Blackwood, and use a group B, horizontally polarized outdoor aerial

    So confirmation once again that local TV coverage is going to be better than expected, the extra robust transmission mode really helping.

    The B'ham Local Mux of course being beamed SW from Sutton Coldfield towards Birmingham, and then on to you in Worcester. Sadly, it can't beam northeast as it would disrupt signals from both Derby and Nottingham transmitter sites!

    No, no signal present on UHF channel 29 from Crystal Palace.

    It is supposed to be on UHF 29 from my local transmitter at Brierley Hill. Not there yet though.


    Then again, i seem to remember it had a licence issued for a local RSL back in the Analogue days which never made it to air. Here's hoping it makes it this time

    The signal from Cambridge local TV will just graze the bottom of the CB7 5** postcode area. London Live will be on satellite, but only on Sky channel 117 in its core coverage area. We don't know which satellite it will appear on or which frequency for manual tuning purposes either via Sky other channels or for Freesat receivers, non-Freesat mode.

    To note that the mux launch date for Birmingham is 30/01/2014. London mux launch date not until March (according to Ofcom documents).

    Just had a check of UHF channel 51 here. Seems 51 from Derby relay stronger than usual (normally not enough to sustain a picture, just an occasional trace of a signal). Other UHF channels from the same relay not receivable. I don't know if its just the current conditions favouring a usable signal on 51 only from Derby, or if there's been a few tweaks in view of B'ham local mux launching. The Ofcom coverage map for the local mux showed a small 'splatter' in the direction of Derby.

    The antenna for local TV in London only went up the Crystal Palace mast just under two weeks ago. It'll be 2014 before you see tests in London.

    yeah wasn't it "black country tv" or something...

    I suppose I'll have to stick a Sutton Coldfield aerial up aswell as the 1970's Brierley Hill one to see what the new muxes are like around here.

    Yep. http://www.wolfbane.com/articles/uktv2.htm - bottom of the page is the most complete RSL data I'm aware of (although some of it seems "out of date" if you get my meaning)

    Uktv site map for this local Tv service area shows the usual shadow over Worcestershire caused by the Lickey Hills on the South side of Birmingham.
    As slight off topic note....The Lickey Hills has always been a band site for transmitters but recently a DAB transmitter was installed on a Severn Trent water tower for one of the Birmingham multiplexes and although low power it puts the best signal out into Worcestershire down the M5 and beyond.

    The local muxes will carry more than just a single local service, there will also be other national syndicated channels

    Not sure if it's just my TV Card throwing a wobbley or not but it's recording what appeared to be an empty multiplex from Waltham about 15 minutes ago (and 30 minutes + 1 hour before that).

    Each local multiplex will carry three tv stations

    1 local television station (on Freeview channel 8 in England)
    2 "national" services - these have yet to be announced but will be available on all multiplexes carrying local tv services.

    For example if the 2 national services happened to be movies4men and Capital TV* anyone who gets a local station will also get those.

    e,g, in Preston you'd get
    1. Your TV Preston and Blackpool;
    2. Movies4Men*
    3. Capital TV*

    in Nottingham you'd get
    1. Notts TV
    2. Movies4Men*
    3. Capital TV*

    in London you'd get
    1. London Live
    2. Movies4Men*
    3. Capital TV*


    * Used for examples only - no idea what the actual services will be

    Hmm, there is something there - however only one of my tv cards can see it, none of my tv's can tune to it - however my Humax PVRT is showing 58% signal strength and 10% signal quality (vs 85% and 100% on the PSBs and 21% + 0% for where there is just background noise) ~ 45% strength was plenty high enough to decode pre-DSO COM5 and COM6 though

    In short, there is capacity on the local TV muxes to carry an additional 2 SD channels or 1 HD.

    It's a multiplex, therefore it can carry several video channels, the multiplex owner can therefore subsidise the cost of operating the multiplex, by carrying other material, which is very likely to be nationally syndicated tat, such as 'info-commercial' shopping channels etc.

    Don't get too excited by what's coming on those :cool:
