The symbol shows the location of the Bilsdale (North Yorkshire, England) transmitter which serves 570,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Is the transmitter output the same in all directions?

Darren Brown: Have you had your Group A aerial replaced with a wideband or Group K one?
The Commercial (COM) channels from Bilsdale are out of the former analogue group.
If your aerial hasn't been replaced, then it may be a Group A one which means that it is most sensitive at frequencies within the bottom third of the band. Prior to switchover all analogue channels were in Group A and all except Mux D which carried Film4 and Yesterday were within Group A.
The six channels are:
PSB1 | BBC One | C26
PSB2 | ITV1 | C29
PSB3 | BBC One HD | C23
COM4 | ITV3 | C43
COM5 | Pick TV | C46
COM6 | Dave | C40
Note that the COMs are now in the 40s which is above Group A. Mux D was formerly on C42 at much lower power.
A Group K aerial will be best for Bilsdale now:

Group K covers Group A and Group B; Group B being the middle third of the band, where the COMs are.

Since the switch over my PVR keeps loosing the channels on Com 5. A manual or automatic retune finds them ok but they drop out at random times or if the PVR goes into standby. The digital tv is fine and the digi box on an old tv is also fine....we have a signal booster on because prior to the switch over we had problems with channel drop out and picture break up and the booster resolved it. Although pick tv did remain troublesome on the pvr. Post Code TS17 0SH. Stockton on Tees.
I guess this is an obvious question but does this seem like a PVR fault? and if so why only certain channels and not all of them? Is it possible we may no longer need the booster on since the increase in power output and could this be the problem? I need to get this working because the wife likes Star Trek and likes to watch it after working late....

Alan: Different receivers have differing tollerances and therefore I wouldn't jump to the conclusion that there is a fault.
The thing to be aware of about Bilsdale is that aerials may require replacement because some channels are out of the former analogue group.
In the days of four-channel analogue, each transmitter used four UHF channels (frequencies) from within the same "group". Each group is a portion of the band of frequencies used for TV.
Aerials that were installed were usually grouped meaning that they are most sensitive of one particular group and that they drop off in sensitivity outside of the group.
Bilsdale was Group A (C21 to C37) for all five analogue channels and all pre-switchover digital multiplexes, except for one (Mux D which carried Film4, Yesterday etc). Group A is the bottom third of the band.
Post-switchover the Public Service (PSB) channels are on Group A channels, but the three Commercial (COM) channels are in Group B (middle third of the band). COM5 is the highest of the COMs which is on C46.
The channels are (those in brackets are the pre-switchover channels of the equivalent multiplexes):
PSB1 | BBC One | C26 (C34)
PSB2 | ITV1 | C29 (C21)
PSB3 | BBC One HD | C23 (n/a)
COM4 | ITV3 | C43 (C31)
COM5 | Pick TV | C46 (C27)
COM6 | Film4 | C40 (C42)
Prior to switchover the booster may have been needed because the digital signals were on much lower power. It is, of course, always worth a try without it. But I wonder if it may in practice be being used now to compensate for the weaker signals due to them being out of group.
To understand the sensitivities of aerials, see these example gain curves:
Gain (curves), Again
If, having tried removing the booster, it doesn't work and you decide to replace the aerial I suggest that you get a Group K aerial if you get a yagi type or if it's a log periodic, then these are wideband but have a flatter response than yagis (see gain curves on above link).
See here for some pointers:

Please help me I live in whitby and have always recieved my signal from bilsdale after the switchover on the 26th I have now lost channels like 5+1 5usa 5* dave challange quest and im gutted why is this why have they gone i have retuned 3 times since yesterday and its still not there!!!! help

Jan: Try manually tuning for them. 5+1, 5USA, 5* and Quest are carried on COM4 which is on UHF channel 43 from Bilsdale and Dave and Challenge are on COM5 which are on C46.
Perhaps you need your aerial replacing to receive the COM channels. I covered this in response to Alan in the posting immediately before yours.

I live in Pickering, and have had an acceptable signal on all channels until the switchover. Now PSB1 experineces freezing and breakup. I am using a standard digital aerial and a 4 way booster. I believe this is caused by too strong a signal from BBCA, so I have reduced the gain on the booster. However, the signal is not at all maxing out, (strength 8 quality 7.) If anyone can help with this please. I am using a Thomspon top up tv box

Matt: Have you confirmed that it is not picking up Emley Moor's BBCA on C47 instead of Bilsdale's which is on C26?

Could someone suggest why it might be that the DUK Postcode Checker "thinks" that the Bilsdale PSBs aren't as good as the COMs in the Saltburn-by-the-Sea area?
There appears to be no co-channel transmitters that could degrade reception and the COMs are on half-power to the PSBs. So surely the COMs would be most likely to be not as good as the PSBs, if any.

Up the coast at Seaham, all are "good", but the figures for served and marginal are slightly down for the PSBs:

I appreciate that the DUK is a calculation and therefore there may be variables that aren't totally correct. But what could make the predictor give this result. Could it be Caldbeck?
