Ann: A bit of information that you probably won't want to hear- Midhurst is planned to use C56 instead of C61 later this year as part of the clearance for 4G. With regard to Rowridge, the transmitter now transmits all muxes at 200kW with vertical polarisation, this is double the power normally used to cover the former analogue service area, so together with the polarisation difference you might now have a usable signal. It is important to use a group "A" aerial for Rowridge in difficult reception areas.

So, we will lose even more channels. Great! I can't understand why they are using the same channels for adjacent transmitters.
We have a wide-band aerial, btw. Would that be ok for Rowridge?

Ann: This has happened in other areas. People who could receive the full Freeview service before switchover (and therefore on low power) found that a relay transmitter adjacent to them which they do not use wiped out any chance of receiving the Commercial channels (which the relay doesn't transmit anyway) when it came on air at switchover.
As an example, Steyning transmitter relays Midhurst's Public Service channels and rebroadcasts them on the same channels as Midhurst uses for its Commercial services. So those living in places where they can receive directly from Midhurst but close to Steyning transmitter will probably find that they can no longer get the Commercial services from Midhurst.
The reason that it's like this is because of scarcity of frequencies and the requirement to fit it more services, albeit that they (the Commercial services) are quasi-national.
In the days of analogue, all transmitters had four channels each. Now the main ones that serve large areas have six and the "filler-in" relays have three.
Midhurst is one of those where the transmission power of the three Commercial channels are lower than that of the Public Service channels. The "re-use" of these channels in closer proximity to the re-use of the Public Service ones is probably the reason for this.
As KMJ,Derby says, a wideband aerial isn't the best for Rowridge in poor reception areas. The sensitivity of these aerials is lower at Group A (bottom third) channels which Rowridge uses exclusively. See these plots:

Thanks. There must be a great number of disgruntled viewers, then.
Why is C50 from Horndean not picked up, though - not that I want it, as it is D3+4 and not ArqB (as from Midhurst).
My husband wondered if an attenuator would be sufficient to stop the Horndean interference as it is only 5w. What do you think?
| link to this comment |
Ann: You aren't picking up C50 from either because they are corrupting one another. Your aerial faces Midhurst and so picks up some of its C50 signal. However, even in that position, evidently, it picks up enough of Horndean's C50 to render either unuseable. In essence what you have coming down your aerial lead is the sum of both signals.
Remember that the aerial is most sensitive in the direction to which it faces, and is less so in other directions. However, it is probably in such a location that the unwanted signal is so strong that the lesser sensitivity in that direction (than forward facing) is still sufficient to pick up that signal.
I doubt that attenuation would help. The problem is that you would be reducing the level of everything coming down your aerial lead. So now have you a "large" poor quality/corrupted signal. Attenuating it will give you a "small" or "smaller" poor quality/corrupted signal.

I have followed your advice about removing the aerial whilst tuning through unwanted channels and the result is fantastic. We receive all the correct channels perfectly. Thanks

We have a new wideband horizontal aerial installed in the loft under the switchover help scheme pointing at Midhurst with an excellent signal according to the installer. I cleared the tuners on my 2 digital TVs as recommended on 25 April and retuned them . I still receive fluctuating signal quality (0-6 out of 10)on the 3 multiplexes C50, 58 and 59 which makes them unwatchable.
What should I try next?

Could someone please let me know when the power for ArqA, ArqB and SDN will be increased. It's very frustrating not being able to receive these FREE channels, missing out on great films etc.

Andrew: The COM muxes are now all transmitting at 10kW from Midhurst, which is full power for the current post DSO network.

Sorry to contradict KMJ DERBY,still no Tx Channel 50 from Midhurst after several retunes over different days since APR 25th. Getting Tx Channel 28 from Crystal Palace though. RH121SY We have comummal aerial.
