I notice the disparity between the Gross and DPSA figures for the Dundee area, and having read the Ofcom document and looked at the map, I don't think it equates to poor coverage.
Given that the coverage area shown on the map extends to the Edinburgh area, I presume households in the Lothians are being included in the Gross figure, but that is irrelevant if the target area is Dundee and Angus (I think Perth may be stretching it)
:-).

Dave Hunter: It's probable that your BBC channels are coming from another region. A common problem due to lack of foresight when the receivers software was written.
You may find your proper BBC channels in the 800s You may just have to put up with that for now because the popular trick of removing the aerial during during the scan will not be that useful at the moment due to the spread of the other multiplexes for the next 2 weeks.
Instead, if you can, delete all the BBC channels from the channel list then manually scan UHF channel 61.
If someone knows where the problematic BBC channels are coming from, it may help

Regarding the North and Tayside opts, you get one or the other on channel 3, but the other NEVER shows up separately in the 800's.
Easiest way to get the Angus signal is to pull the aerial out and start a scan, plug the aerial in just before it gets to UHF channel 53 or about 2/3s of the way through. :-)

Sorry I was incorrect above, some receivers do allow both to be present, others don't. My LG TV does, my Vestel-based PVR doesn't.

Adrian, I saw this answered on another site. The broadcasters switch dynamically between 1080i and 1080p to maximise picture quality. Your TV has different picture settings for each of these modes. You need to alter the zoom setting for each mode so they match :)

David Wall: You could argue that transmitters that serve major population areas are over-powered, it goes back to when the first TV transmitters were established, they were designed to cover the largest area possible with one mast, and with 405-line VHF signals they covered the country quite well. UHF signals don't travel so well and more transmitters were needed. Angus is really just a fill-in between Durris and Black Hill.
I never thought about the Watts per viewer argument, but it seems to make sense.
Another way to look at it: if 10kW can cover 95% (say) of viewers and 20kW can cover 99%, that's twice the cost to reach 4% more people, not worth it in commercial terms.

Just to let you know, the FEC mode changes announced for 2/11/11 and 3/11/11 on Angus haven't materialised.

Mike (1): In my experience Panasonic DTT equipment can have an unsatisfactory tuning routine. I've had a Panasonic Freeview box and DVD Recorder, and I've heard from others with Panasonic TVs.
This equipment finds a multiplex from a distant transmitter during the early part of the channel scan and then ignores the identical multiplex from your desired transmitter.
So it's quite likely that you are getting Durris multiplexes in place of Craigkelly.
One answer to the problem is an attenuator to weaken the signal to the point where unwanted signals are not detected but the wanted signals are still powerful enough. After a scan you can remove the attenuator if necessary. If you don't have an attenuator any way of weakening the signal would do.
