I notice that there are two test transmission channels from Comux this morning. Made in Bristol gets one. Does anyone yet know who gets the other?

Local MUX now on CH 51, showing colour bars on 791 & 792. Odd how Kings Weston Hill has been on now for a few days, is KWH a relay of Mendip in this case or is it directly fed?

Iain Davies:
The test transmissions showing old US programmes on the Bonanza channel (it used to be on the Sky line-up a few years ago) also started from Waltham yesterday.
Here in Notts., Test 1 is still showing colour bars whilst Test 2 is showing Bonanza programming (including adverts!).
Both Test 1 & Test 2 are being broadcast on Ch. 26 (514.00 MHz) with no interference.
Iain, I can't understand though why you're receiving Ch.64 because that's no longer used for tv. Your local relays at Ilchester Crescent and Kings Weston Hill will both use Ch. 30 and Mendip Ch. 51

Jim: I'm not sure if it's a trailer or the actual channel...

Jim, no the ref. to CH64 in on the Freeview EPG the broadcast channel as you say is on 51. In Weston super Mare the signal is not that strong but it does tune in with no break up.

So it is appearing on Logical Programme Number 64 and not Channel 64, that's now in the spectrum being used for 4G.

Hi Briantist and Iain D,
The 'Bonanza channel' programmes seem to be showing in their entirety on Ch.792 as Test 1, which from Waltham, also appears on the Freeview EPG.
Test 2 (colour bars) is coming up on 811 but doesn't show on the EPG (presumably because there are no programmes!).
There's nothing on EPG Ch. 64 here.
Does 'Bonanza' actually broadcast anywhere in its own right?
Regards.
