The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

comps: A log periodic type such as a Log36 (see link below) would be more suitable for of . It would be much more compact than the one you've linked to and would likely give better reception of frequencies at the lower end of the UHF band such as those used by Crystal Palace (a 4G filter is very unlikely to be necessary for the same reason).

Terrible strength for London Live (538Mhz) in BR6 (Bromley)?
I'm in what appears to be in an excellent position to receive all channels from and, indeed get 100% reported by my Humax T2 for all relevant frequencies except 538Mhz, which is reported as 10% signal and 10% quality by the receiver, effectively rendering London Live unwatchable.
Whilst this is a regional channel, can anyone advise of there is any reason why this should be the case, given I'm in a relatively high location, only a handful of miles from the and with excellent on all other channels?
Thanks

And:

You should be getting quite strong signals from as you are so close, maybe too strong and that may be the reason. Please check the strengths of all the multiplexes, they should be between 60% and 85% for reliable . If they are all higher than this you possibly need to add some attenuation. If they are mostly below 60% then you could have an fault so please check all the aerial connection from the back of the TV set.
Would you please give a full post code (BR6 Bromley is not enough) to trigger the display of the reception information - you may have seen the series of blue link boxes below other posts. From those we can see what reception is expected to be like at your location and see if the 29 (538 MHz) signals are likely to be reliable. Note that the LW is only 20kW whereas the main multiplexes are all 200kW, so it is much lower strength and it may have a directional pattern too.

I know this say's UK(Free-TV) but this is a radio question - can't see a specific place to ask radio questions.

I've selected as the best and have been using it for some time, and all is well except LBC Radio, which has recently lost it's EPG. Other EPG are okay, and the LBC programmes are being received okay.

The other point of note is that LBC radio has been on channel 856 for some time, although it appears to be listed elsewhere as being on channel 732, which I think that is what it was on before it was move some time ago.

Could it be that the LBC Radio EPG has been lost because of a continuity mix up somewhere?
And if so who can fix it please?

Colin Knight: The 800 range is where TVs and /PVRs put that they don't know what to do with (e.g. duplicates from another etc). Try a manual tune on UHF channel 28, which should restore LBC to channel 732, however if that doesn't work make a note of any planned recordings then disconnect your and run a full which should delete all of your channels, then reconnect your aerial and scan again.

StevensOnln1:

Thank you.

Doing a with the disconnected has sorted it out, LBC radio is back on 732 with its EPG updated, and all is well again.

Just for info, I'm using the NextPVR program on Windows 7, with a couple of RTL2832U+R820T USB dongles.

DO NOT RETUNE. Instead, check all the cables and connection behind your TV.

Either you have it zoomed in too close or else your browser does not support the way it's done. Try a different browser. I use Firefox normally and that works fine. I sometimes use Chrome and that sometimes has the same problem as does Opera on occasion. I don't know about Safari and I never use IE if at all avoidable. I don't have W10 so don't use Edge so can't comment on that.
