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, 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.

From Mendip at the moment BonanzaBonanza is on EPG 64 Local test 1 is still on EPG 791, which should go to EPG 8 when in full service. So the question is will there be other channels on this CH 51?

Iain Davies: Well, giving Ofcom | Television Broadcast Licensing Update January 2014 as a guide, I would guess we're due to see "ABC Shopping" very soon!

There are two "quazi-national" channels that are being used to support Comux and the network of local stations.

I noticed recently that Channel 5+24 started broadcasting on channel 55, that ITV4+1 is now showing on the EPG at channel 54 and Quest+1 at channel 57. I assume that this indicates that the compression technology is getting even more efficient, even within the constraints of DVB-T. (I haven't noticed any services ceasing to broadcast.) How is this being achieved and does this mean that DVB-T2 can also provide more channels because of improvements to compression technology? (51.4634,-2.5264)

Seeing that Bonanza has commercials, I am of the impression that it's a permanent new channel, rather than some kind of test transmission. (51.4634,-2.5264)

Further to my earlier postings, Waltham (as Mendip) is now broadcasting 'BonanzaBonanza' on EPG 64 (it no longer states Local tv Test').
It was showing the usual old US programmes on Friday evening plus an hour of Teleshopping.
Comux - Local tv Test 1 (colour bars) is on 811.
