I'm in a RF hole in Bromley but can go mobile to nearby hills if they have a LOS to Rochester. One in particular looks over London and may go easterly enough. Lots of gain this end.

Or better still connect it to the composite video out of your Portsdown Raspberry Pi and you can use the Portsdown test cards:

Is it possible to capture the analog video out from the Portsdown so I could store the test card on, say, an SD Card?

Actually, I have just found a rather nice little free app in the Mac OSX App Store. It is called TestCard and is dead easy to use with export available as PNG. It will certainly do me for my 5.6ghz testing.
