Hi, Now on Freeview since 21st March on Piddletrenhide booster Xmitter in Dorset, fed off Rowridge. Picture is reasonable, but...only getting 22 channels & not Sky news or ITV3 & 4. How many channels should I be receiving from this Xmitter? Aerial on roof, using iCan 285IT digital box.(Box obviously tuned after Digital switchover & factory reset!) Thanks for your help.

Bernard Roughton: The Piddletrenthide relay only transmits the three PSB muxes (a Freeview Light transmitter). It is possible that you will be able to receive the COM muxes when using a suitable aerial from either Mendip after the power increase on 28th March, or Rowridge VP after the transmitters enter service on 18th April 2012. Mendip requires a group C/D aerial set for horizontal polarisation, Rowridge VP requires a group A aeerial set for vertical polarisation. You could try C48 now for SDN from Mendip, as this transmitter is at higher power than the other muxes.

Bernard Roughton: Piddletrenthide is only a Public Service transmitter; the Commercial broadcasters do not wish to pay to transmit from this and 1000 or so similar small relays. They achieve around 90% coverage by using 80 of the biggest sites (by viewer population).

To transmit from the rest would roughly double their cost of transmission They were asked if they wished to increase coverage and they declined. They are private profit driven organisations and generate a return by selling advertising which they show to as many people as possible at lowest cost.

See here for a further explanation:

Will there ever be more services on the Freeview Light transmitters? | ukfree.tv - independent free digital TV advice

The Digital UK Tradeview predictor suggests that your reception from Rowridge may be "good" for the Public Service Broadcaster or PSB services (those are the channels relayed by Piddletrenthide), but "variable" and "poor" for the Commercial or COMs (the ones that you don't get now).

I guess that the reason for the lower rating of the Rowridge COMs is due to possible interference from Stockland Hill as its COMs are co-channel with Rowridge's COMs (although its PSBs are not).

Mendip is predicted as "good" with some multiplexes being "variable". Two of its COMs are predicted as "good" with one being "variable". Going fully with Mendip would mean a change of regional BBC and ITV programming. Having looked at your road on Google Streetview, I see that there are a mixture of Mendip aerials and Piddletrenthide aerials. They are roughly in the same direction, but the former are horizontal and the latter vertical.

Some suggested possibilities (which will probably need an expert opinion, such as aerial installer, to say how feasible they might be) are:

1. Change entirely to Mendip which will mean a change of regional programming. This will require a single aerial.

2. Diplex (combine) your current aerial with one on Mendip so as to receive its COMs. This will give you BBC South and ITV Meridian, as now, but with the COMs. Be warned that whilst from a signal point of view this is perfectly find, some PVRs have issues where different multiplexes come from different transmitters.

3. Attempt reception of all services from Rowridge. You will have to wait until 18th April for this as its COMs are on low power until then. Once that date has passed, Rowridge will be broadcasting horizontally (as it was before switchover) and vertically. The COMs signals will be more powerful vertically, but the vertical element of the COMs will only become available on 18th April, which is why you will probably need to wait until then to do that. Receiving Rowridge vertically will also help reduce the possibility of the possible interference from Stockland I mentioned as it is transmits only in the horizontal plane.

4. Increase the number of channels you have with Freesat. There are some services such as Sky News and Dave that aren't on Freesat but are on the full Freeview service. If you used this in conjuction with a Mendip aerial, you could then get all the channels available on Freeview (but not on Freesat), plus you would be able to receive BBC South/ITV Meridian via satellite, negating the need to connect the current Piddletrenthide aerial. It might be a good idea to retain (even if you don't use) the current aerial as a back-up or if you decide to change the arrangement.


P.S. One other thing to mention is that in the future it is expected that there will be three more licences granted to Commercial broadcasters. Expect these to not bother with Piddletrenthide but transmit from Mendip and Rowridge.

Because of the UHF channels they are likely to use (somewhere from 31 to 38 from all transmitters), this could perhaps present a problem, particularly if you go with option 2. It may be that in the future you may need a second aerial for the new services from Mendip. You might like to raise this potential issue with the installer, should you decide to go down this route.

If you go with option 3 (a single aerial on Rowridge) you will be OK.

If you go with option 1 (a single aerial on Mendip), then this will need to be a wideband aerial. If it is a Group C/D aerial, then you will need a second aerial for the new services. Again, best to raise this with an installer.

I add this P.S. as a warning, so that you aren't taken by surprise (and perhaps annoyed) that in a few years time you find that you have to have more work done in order to receive the future Commercial services.

Thank you to KMJ & Dave Lindsey for taking the time to answer my query, much appreciated. The Dorset village I live in went Digital last week, & as I was BBC staff for a long time (Film unit, not engineeering!) people here have asked me questions about their about Freeview problems, which your replies help me to answer. Any other comments you may have would be gratefully received!
Thanks
