Where did you get those numbers from? How could I find out which numbers
I should be using for the Mendip transmitter? The numbers seem to be
different every time I do a full scan. I have tried to pick and choose
different ones, but it has been guesswork.

Thanks
Damian

A bit of investigative work and luck (they work for me).

The first one in the list was the new frequency for the BBC Mux that
just worked. The other multiplexes where automatically tuning with
the offset of 000000 but I had the previous frequencies noted down
before switch over and tried adding the offsets back and this sorted
my locking problem out.

It is also worth noting if you have changed TV tuning cards some card
drivers automatically try different offsets when tuning so they just
automatically work even if the offset is wrong. My Hauppuage USB
sticks do *not* so you need to ensure the offsets are correct.

There is a good chance your offsets are wrong if MythTV sort of Locks
to the channel in LiveTV but does not finish the process off (i.e. the
L lights but the MS does not).

Perhaps wait to see if someone posts the correct frequencies (and
offset) for your transmitter. If they do not try posting with a new
thread with a better subject with Mendip transmitter near the
beginning of the subject text as most people will just see Winter Hill
and ignore this thread.

I just wanted to follow this up in case anyone else is having a
similar problem I missed a couple of recordings yesterday using the
810000000 frequency (channels ITV4/V1+1). This frequency appears to
be very low quality for me so I had to use the alternative Mux D of
626000000. Hopefully at beginning of December when this alternative
frequency (Winter Hill B) is switched off Mux D will get a power
increase which will mean 810000000 will work.

Additionally, ukfree.tv (http://www.ukfree.tv/txdetail.php?a=SD660144)
reports very low power for all muxes on Winter Hill apart from the
BBC1 mux. The 10x power increase in December should help things
considerably.

Cheers,
Nick
