Freeview signal from Rowridge stops for 2 or 3 minutes and then restarts. This has been happening for the past 3 - 4 weeks but not on all Rowridge signals.
My postcode is SO31 4JQ at Hamble-le-Rice. My neighbour has the same problem and has a separate aerial.

Can someone tell me why on the Rowridge Transmitter all of the COM Muxes (on Vertical) have been put on reduced power, in e.r.p, (down from 200kW to 50kW)? I have cross-checked this information on digitaluk.co.uk's website and it tells me that all Muxes (on Vertical) are still at 200kW.

Is it that there is an error in the site or what?

I am at PO15 5LS for your information.

Kind Regards,

Andrew Murphy.

Andrew Murphy: Are you reading just 50kw, or have you found that figure somewhere? Because obviously if your reading a low signal strength, but the transmitter is fine, then that points to a problem at your end.

Andrew Murphy : I suspect that its an error on this site, as the Vertical COM4/5/6 power levels are still indicated as being 200Kw everywhere else.

jb38: Sorry about that, I have a system that checks all the values here everyday against the Ofcom master data. It seems to have not looked correctly when a transmitter has both vertical and horizontal outputs. Of which there are very few and Rowridge is the only main one.

Briantist: Re; System malfunction caused by variation in Rowridge V/H power levels. Yes, this station is indeed oddball in this respect, however, said malfunctions can obviously occur in the best of systems, but with in my opinion, your site being relatively free of errors considering the complexity of same.

Hi, I want to programme the freeview to only receive the south coast broadcasts. But I'm picking up about seven different BBC one's!

Hope there's a simple solution?

Pete: What make/model TV or set-top box are you using? Some have a function to allow you to delete channels from the program guide.

StevensOnln1: I have that problem with my Sony recorder - the tuner is so sensitive that it picks up another three transmitters, but sometimes latches onto a programme from the wrong one, thus messing up the recording.

I partially solved it (or at least made it slightly better) by using an attenuator, or rather a series of them. It will still bring channels up in the 800's, but apart from BBC1, it wont do anything about them.

I cannot see the colours orange and yellow on the output in each direction diagram. I can see blue . violet and red. Does this mean that COM5 output is full in every direction ?
Thanks
