B Moreton : Although its unlikely that it wouldn't be. but on the signal check you carried out make sure that you are receiving mux Ch45, this bring Plympton's COM5 as used by Sky news (82) as well as Pick TV (11) and Dave (12).

However, in order to make a proper assessment of the situation a more accurate location is required, this in the form of a post code or one from nearby as a test code using Plymptons Post Office indicated it as being under 1 mile away from the transmitter, and if you are anywhere near to this location then your aerial system would be grossly over the top and liable to overload your receiver.

Further info dependant on reply, but just in case you are not receiving from the Plympton transmitter but Caradon Hill then its COM5 is mux Ch24 and with the aerial being mounted horizontally whereas Plympton is vertical, elements up and downwards.

JACK: In specific response to your question: because different frequencies behave differently, and particularly so in situations such as yours where there is no line-of-sight to the transmitter and you have trees in the way. So, in actual fact the question you are asking is why does ITV come in OK?

The Digital UK predictor doesn't predict anything. The terrain plotter shows that the ground rises up around 100m within approximately three-quarters of a mile:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


This is hardly a recipe for interruption-free viewing!

You only mention PSB channels BBC and ITV. As you have ITV, it follows you must have access to Channel 4, Channel 5 and their six other sister services.

But do you receive the Commercial (COM) channels, these being (10)ITV3, Pick(11) and (18)4Music?

JACK: I have looked further at your situation. In your posting you said signals came from "cornwall" which I now understand to mean from Caradon Hill. Whilst it's not great it may be so, this plot showing that Brownhill is your only obstruction at about 80m above you:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


With this in mind I would confirm that for ITV you are tuned to UHF channel 25 (506MHz or 506.2MHz) and not UHF channel 49 (698MHz), this being the frequency of Plympton. This information is usually given on the signal strength screen.

If it turns out to be tuned to Plympton then run the automatic tuning scan and unplug at 30% or when the scan gets past UHF channel 30.
