I'm asking, because when I use a roof antenna, I receive BBC 1 at
505833, while when I use the in-wall provided signal, which goes through
at least one amplifier, I receive it at 506000, although most programs
try to re-tune to 505833, since the signal apparently contains
information to ask them to do so. (I don't know the correct terminology
So I'm suspecting that you see the same as I do in regards to offset.
I haven't been able to receive the test transmissions from the in-wall
signal though. What exact parameters are you using to receive it?
