are now on air
791 Local TV Test 1
792 Local TV Test 2

Both carrying test cards saying "Comux-local TV test"

Signal strength being reports as 63% on my PCTV Nano Stick vs the 82% of Multiplex B.

Wenvoe is now carrying the same test transmissions on UHF channel 51

Well its one week signal - 29% on my hummy, vs 70% for the psbs, still 100% quality so the qspk is doing the job! Just south of Nottingham on an high gain aerial installed before DSO. Weakest signal I've got without needing a booster.

Are you south of Ruddington?

No - further north nearer the sports grounds (the PSB multiplexes come in strong enough to use a loop aerial from my 14" TV - I'll have to see how the CoMux multiplex performs on that )

Near Edwalton, my Humax is giving a signal strength of 56% and quality of 100% (although this varies 50%-100%). Strength has dropped to 16% on one occasion. BBC strength 75%, quality 100%.
Very susceptible to interference (more so than SDN). This is for loft aerial and no amplification. Hauppauge dongle also connected (from Humax RF out) to this aerial is unreliable for signal strength. Shows a number of continuity and TEI errors. Might be watchable.

My old Philips STB connected via booster to another aerial gives no signal quality.
Using an old roof mounted aerial (pre channel 5 analogue) gives a 75% signal quality on a new(ish) tv. Given this aerial designed for use up at the channel 54-60+ range - not so bad.

FWIW on my Sharp TV on an unsimplified indoor aerial (A Silver Sensor which was able to get Multiplex 1-4 pre-DSO with slight visual corruption but no audio drop outs)

PSB 1 BBC - S: 89%, Q: 71%-75% - No break up
PSB 2 D3&4 - S: 82%, Q: 71% - No break up
COM 4 SDN - S: 97%, Q: 71% - No break up
COM 5 ArqA - S: 82%, Q: 59% - No break up
COM 6 ArqB - S: 78%, Q: 50% - Some MPEG corruption artifices and sound drop outs
L-NOT - S: 53%, Q: 18% - Some MPEG corruption artifacts (less than on Arq B though) but no sound drop outs. Suffering from impulsive interference (i.e. boiler starting)

No sign of the multiplexes from Nottingham at all so can't check those to see if CoMux is a go there...

24% signal strength but 100% quality here in Long Eaton.

Signal here is 68% in North Warwickshire with a booster.

Btw kev, you really should update your TVheadend install and secure your site directory

Hmm, they aren't really controlling the radiation pattern of these local tv services very well are they? Wonder if that's why Winter Hill is so late on in the list - trying to get three different multiplexes on the same frequency should be fun!


TVHeadend is on the latest release one and that directory is intentionally open for these random screen shots Should really set-up a proper gallery thing though

Just south of Spalding (Lincs), via my boosted wideband aerial on Waltham, I'm getting around 75% strength and 100% quality of the Nottingham local TV tests, consistently since they started.

Not too surprising considering that Spalding is the only town the Notts TV local multiplex has full coverage of according to the predicted coverage maps!

I hadn't seen the predicted coverage map, I see what you mean! Spalding can hardly be within the intended area for Notts local, so I assume it will carry nothing of any interest for south Lincolnshire. We'll have to stick with BBC 'Derby Today', sorry I mean East Midlands Today and 'Look Hull', sorry, Look North. A Peterborough local service might benefit this area but I gather there are no plans for one.

Loughborough is returning 18% with 100 quality. Is that it or will they turn the power up a bit?

I feel that we are returning to the 1998 when digital TV started with the have and have not's service with those in good weathers that can without blocking.

We have HD mux that is low powered with second said to come along later, but both under a 5 year only contact.
And now local mux which is even lower in power from transmitters, that well make city and town people up to three channels richer on the poor DTT system.

We have many before DSO that in the pass year may have taken away amps thinking that all new muxes will be same powers, But no OFCOM has now made the power amps needed again.

Well it makes a change from the accusation that East Midlands Today only covers news within a mile radius of the London Road Island in Nottingham...

There are two ways to upgrade the broadcast infrastructure. We could just have one system, and then a "big bang" changeover where one night we shut it all down and start up something completely new from scratch and we the consumers have to all change all our kit on that single day, and the broadcasters get no opportunity to publicly trial the new system. Would you like that? Can you imagine the outcry as that took place?

Alternatively, we have the main supported full power system- analogue before DSO, and Freeview after DSO. But at the same time we fit in - at lower quality, reduced coverage- a second system that is effectively the next generation of technology under test. Before DSO, it was Freeview/DVB-T that was being tested. Now that's become the main system we're seeing the next generation again being introduced into the lower power/reduced coverage regime. At the next switchover DVB-T2 will become the main technology, and something else will start to appear in the reduced coverage slots if there's still enough bandwidth left to do that- else the trials of (e.g.) UHD TV over DVB-T3 will be much more restricted.

The power on the local TV multiplex is less than that of Multiplex 2,3, and A were pre-DSO - and either equal to or slightly higher than multiplex C and D were. Looks like the more robust transmission mode means that pre-DSO aerials which required boosters for multiplexes C and D can get the Notts Local TV multiplex without them (thankfully as a booster wrecks the two PSB multiplexes!). As I've already mentioned I can just about get the Nottingham multiplex on an indoor aerial - pre-DSO I wasn't even able to get any form of picture from Multiplex C and D so it's certainly a bit more robust. Of course being the same strength means the signal strength readings are going to be on the low side especially when compared with the PSBs!
