This morning I tried to view HD channels 107 (BBC News) and 108 (Al Jazeera)
Both were breaking up. This is from Crystal Palace. Lots of complaint messages from others but I couldn't find an explanation anywhere. -- Mageia 5.1 for x86_64, Kernel:4.4.114-desktop-1.mga5 KDE version 4.14.5 on an AMD Phenom II X4 Black edition. |

Lots of complaint messages from others but I couldn't find an explanation anywhere. Last Wednesday morning (March 21st) COM 7 and 8 from Crystal Palace moved from UHF Ch 33 and 35, to 55 and 56 as part of the three year long 700 MHz clearance scheme. You most probably have a Group A UHF aerial, and if so both these muxes will now be beyond the frequency range of it. -- Mark Please replace invalid and invalid with gmx and net to reply. |

A few houses on the Northern fringes of the sussex village where I live seem to have aerials pointing along the line of stane street. This is the Roman road to Londinium, so presumably CP, because I cannot think of any transmitters in the 37 miles between me and CP. One of them now has one of those Tri-boom wideband jobs on a wavy, wibbly wobbly pole in the garden. It has white coax so presumably a diy job. I didn't think we could get CP down here, but they are on high ground, while I only have line of sight to Midhurst. Grrr. |

Before my time - Once Rowridge came on, there would have been appaling adjacent channel interference, but pre-Rowridge it might have been possible. In the 405 days - who knows. I could get Rowridge here in a strong CP area. I put the aerial up because Southern had better films than LOndon. -- from KT24 in Surrey, England "I'd rather die of exhaustion than die of boredom" Thomas Carlyle |

Wasn't that using Hannington, or did you also get Southern ITV from Chillerton Down Ch 11 pre UHF ? -- Mark Please replace invalid and invalid with gmx and net to reply. |
