I can only scan if I set QAM64 not QPSK (which worked 3/4 months ago
when I tried the first time).

Since then, I moved, before I was in Victoria and I used a T cable
aerial (the one that is often sold for FM radios), while now I live in
Aldgate East and I use the aerial of the building.

Not much luck here in N7 (Holloway road) using the signal from the buildings aerials.

Done.

I am suspecting this might be due to me using the wall socket signal though, since in order to receive dvb-t services, I have to manually put different frequency information into my vdr channel.conf file. Am assuming it has to do with missing repeater amplifiers for anything but the standard uk television channels.

What kind of antenna would be required to receive these signals?
