The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. 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.

Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

Thank you Mikes B & P.

The strengths of channels 33 and 35 are well down, but that possibly reflects the reduced transmission powers. However, I'm looping the aerial through an old Humax PVR and eventually came to realise that ch35 was disappearing whenever the PVR was turned on - I hadn't spotted that coincidence before. Turns out that the PVR was modulating its own output onto ch36 which was interfering with ch35. Now moved it up the scale and all is well. Perhaps a warning to others who had forgotten that these devices add their own signal to the aerial feed.

Many thanks again.

Is this aerial ( see link )suitable for Cyrstal Palace reception from postcode CM166Hu? outdoor installation, I want as compact an aerial as possible. What about 4g interference,should I buy an inline filter?

comps: A log periodic type aerial such as a Log36 (see link below) would be more suitable for reception of Crystal Palace. 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 signal strength for London Live (538Mhz) in BR6 (Bromley)?
I'm in what appears to be in an excellent position to receive all freeview channels from Crystal Palace and, indeed get 100% quality reported by my Humax T2 receiver 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 transmitter and with excellent reception on all other channels?
Thanks

And:

You should be getting quite strong signals from Crystal Palace as you are so close, maybe too strong and that may be the reason. Please check the signal strengths of all the multiplexes, they should be between 60% and 85% for reliable reception. 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 aerial 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 channel 29 (538 MHz) signals are likely to be reliable. Note that the LW multiplex 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 Freeview radio question - can't see a specific place to ask radio questions.

I've selected Crystal Palace as the best transmitter and have been using it for some time, and all is well except LBC Radio, which has recently lost it's EPG. Other channel 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 set top boxes/PVRs put channels that they don't know what to do with (e.g. duplicates from another transmitter 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 aerial and run a full scan which should delete all of your channels, then reconnect your aerial and scan again.

StevensOnln1:

Thank you.

Doing a scan with the aerial disconnected has sorted it out, LBC radio is back on channel 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 receiver dongles.

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