UK Digital Switchover - w_scan results for Mendip transmitter

UK Digital Switchover - w_scan results for Mendip transmitter

[Rupert Plumridge]

Hi

As part of the UK's digital switchover, it seems some of the pre-set
mux information is now out of date. I don't know the technicals here,
but for example adding channels to tvheadend git version now fails as
the mux information at my location is out of date.

I used w_scan to check the current situaiton and it gave me the
following for the Mendip Transmitter (since that is where my antennae
is pointed):

The #West settings seem to work for me on tvheadend, ignore the #Wales
ones, unless you want all the welsh channels, which you don't.

Hope this is useful. It is all beyond me.

Hi Rupert,

It looks like you're picking up more than just Mendip there; Mendip only
has 6 muxes: http://www.ukfree.tv/txdetail.php?a=ST564488

Unless it's announcing other frequencies? I'll do a rescan in MythTV and
see what happens.

As the switchover progresses and transmit powers are increased, however,
some antennae will pick up signals from more than one transmitter. So we
should be careful not to assume that the muxes we see are necessarily
from the transmitter we think we're pointing at!

Cheers,
