Oxford (Oxfordshire, England) Full Freeview transmitter

Like Shirley, I get unwatchable reception on ArqB (C55), but I'm in Oxford using a communal aerial system with a pretty good direct line of sight to the transmitter.

My Thompson DTR-2300 didn't have any indication of signal strength, but my new Vestel T8300 clone HD box does and shows None for signal quality and around 65% on the signal strength for ArqB. All other muxes are Good or Very Good signal quality and only SDN (C62) is below 97% strength (it is 83%).

Before the digital switchover, Mux D (C29) was fine, so we must have a wideband aerial system, but Mux2 (C68) was always very poor. On my Pace DTR730 Mux2 showed satisfactory signal quality and 1/4 signal strength. All of the other muxes were good signal quality and 2-2.5 signal strength and mostly.

My suspicion is that we now have some single frequency interference at C55 which is causing our trouble.

Briantist: Thanks.

Out of interest, how wide a band do these communal system boosters cover?

The reason that I ask is that ArqA and SDN are also on new frequencies (C59 & C62) and they are working fine. There were channels on C60 and C63 before though, so I guess there are probably boosters for these adjacent channels.

In contrast, the closest previous frequencies to ArqB's C55 were C53 & C57.
