Paul: Yes, Hannington might well be, but I think you are overlooking the fact that apart from it being roughly 50 miles away from Oxford its also only transmitting on low power (20Kw), so if any signal was actually received (which is very doubtful) then its most unlikely to be at any level that a box could lock onto.

Emley Moor is the only station that does transmit on high power on both Mux Ch's 51 & 52, but once again at a distance that it also can be disregarded for the same aforementioned reason.

Sutton Coldfield does not use Ch50, it having been previously used by Ch4 analogue, although I assume that you have seen this error on Wolbane's site (or what was) when they refer to the PSB3 Mux, as it should be Mux Ch40.

As it was anyway, the box being used did not show channel numbers in the progress bar, making this part of the info supplied to be a bit on the academic side, although I will agree that the aerial out procedure until a certain channel is reached is always a bit iffy, especially when so many stations have their multiplexes weaved between that of other stations.

Thanks for that feedback.
I don't know where I read that SC uses CH50. Thanks for correcting me.
Hannington, even on its current power level, is a problem in north Oxfordshire, where Hannington and Beckley are the same direction.

Chris, sorry for delay, yes. What I am getting is a huge amount of static on the fly lead from the Thompson box. So much in fact that the spark is clearly visible when removing the lead.

On another set, which was working fine on it's own outside aerial I have had to re-instate the booster for channels 15/24 etc. SN3 4ST

Robert - if you are seeing a spark, you may have a dangerous situation. Suggest you resolve that first before doing anything else! Mike

I 've found where I read that Sutton Coldfield uses ch50: it's in the Television Viewers' Guide.
I'm pleased that I'm not going mad.
Thanks for the correction.

Sorry, I should have given the whole picture. I'm getting EPG for Sandy Heath, and some (but not all) Crystal Palace, but nothing at all for Oxford. My box has also allocated ITV Oxford at position 3, but put BBC Oxford in the 900s. I'm getting all 5 muxes (6 in the case of Crystal Palace) on all three transmitters, so presumably it's not that I'm missing the mux that the EPG is transmitted on.

Nicholas: The standard Freeview EPG is transmitted on all multiplexes. Each multiplex transmits its own information more frequently than others, and information about programmes coming up sooner more frequently than later events, but it does all get sent and repeat after a few minutes. Some boxes can get very confused with a mix of different services from different transmitters.

I'd start off by doing a full reset or first-time installation with the aerial unplugged, then doing a manual search for the transmissions from your most preferred transmitters. If that is then reliable, do a manual search for just the regional services (BBC A and D3&4) on your second preferred transmitter, which will put those services in the 800s. If it stops being reliable after that, you'll know where the problem lies.

Some equipment does still use a proprietary EPG. Top-Up TV's EPG is attached to TOPUP Anytime 1, Guide+ to, and RadioTimes Extra to Television X. All three are on Mux A/SDN.

Paul: Ofcom's official documentation of Sutton Coldfield's frequencies was re-issued in January this year, to move BBC B's allocated channel from C50 to C40, and ArqB from C49 to C39. This is part of the plan to free C61 and C62 for 4G mobiles - basically C39 and C40 were going to be freed but are now kept. However, a direct move from C62 to C40 or C61 to C39 would affect a lot of people, as they aren't in the same group, so the compromise is *generally* to move allocations of C62 to C50 and C61 to C49, and move C50 to C40 and C49 to C39, where there is a clash.

Yes, this means there will be another retune at Oxford some time in the next two years, to move SDN from C62 to somewhere else, although it *should* remain in Group C/D.

Hannington C50 isn't particularly low at 20kW, that actually made it joint equal most powerful pre-switchover transmitter, with Crystal Palace, Rowridge and Sandy Heath! Post-switchover PSB power levels are only 4 dB higher at 50 kW (COM power levels are 1 dB higher than at present, 25 kW).

Thanks for responding, problem now fixed - it was a dodgy cable.

Thanks for your reply. My box is ex Top up TV (Thomson; can't remember the model) and doesn't have a manual scan facility.
