Do you think London will be able to receive a DTV signal from Oil Springs after they transition? If not, having them remain analog may be better than the alternative.:rolleyes:

I was making the statement in reference to those near the SW border- see Sarnia, Lake St. Clair area.

I wonder why Global has decided not to duplicate Paris transmitters analog coverage?

Emerald_Boar 2011-01-19 09:08 PM

In Theory, Global has duplicated Paris transmitter, fully.

But we all know that at 4kW. It likely will not be enough in order to receive it. Unless of course you have an VHF/FM antenna. (I do have an FM antenna. I will see then)

As for Sarnia transmitter. The Analog seems to be receivable in the winter time. And the DTV ERP is about the same value. So I would assume if GTN uses the full ERP. (300kW) GTN should be receivable at least in the winter time.

PS. There are many US stations available via FTA satellite.

Well, there is a difference in comparative coverage footprints--as indicated by their coverage map within the Paris DTV transmitter engineering application. With digital being less overall.

My own experience tells me that it's possible to view a snowy analog station--far below the threshold where a usable digital signal could be viewed. Thus, I see the Paris DTV signal reaching far less viewers....

That is a big if. It is highly unlikely that CIII-DT-29 (Sarnia/Oil Springs) will actually use anywhere near that ERP.

True. Also, VHF-LO has proven to require 20dB more power than the models predict for reliable reception so those contours are very much wishful thinking. GTN, the CRTC and IC don't seem to care though.

Can anyone verify that we have a recourse with the CRTC if the predicted level of service is not what actually happens? If I complain after the fact are the obligated to fix it?

stampeder 2011-01-20 12:50 PM

Yes, you do have recourse. Keep a printout of their conditions of license, and if those conditions are felt to have been unmet then raise the issue promptly according to the specifics.

That doesn't mean that CIII-TV's application hasn't been approved yet, only that it wasn't approved during the time period that this bulletin covers (1 May to 30 June 2010).

Has anyone heard any word on the status of CIII-TV-22 Stevenson? The CRTC listed it as part of the Windsor market from back in the day when the transmiter was in Cottam and could actually be reliably recieved in Windsor and has mandated it for mandatory transition by the deadline, but I see no information on it outside of Shaw saying they would spend $4.6 per year to convert the analog retransmitters to digital.

Anyone think they will actually make the deadline?

Truth be told I would rather see CIII-TV-29 converted as I find its reception comes in more reliabily in the Windsor core.

Phil81 2011-03-17 06:15 PM

Isn't CIII-22 part of the Windsor market? It along with all the others locally are supposed to be digital by 8/31.

Looking forward to 22 in digital. Much lower power will cut down on multipath reflections. Never could get a decent analog picture without excessive amount of ghosts.

I would guess 29 is better there because of antenna HAAT. 22 is rather poor at 110m. 29 is 208.8m

In 1986, the CRTC approved the relocation of the Windsor-area transmitter from Cottam to Stevenson.[5] This transmitter (then CIII-TV-1) was silent for several years following a transmitter fire in the late 1970s. Some time after this, the CIII-TV-22 call letters from the now-disused Uxbridge transmitter were re-assigned to the Stevenson transmitter. The transmitter is located northeast of Wheatley, but its signal is aimed northeast (towards Chatham-Kent), and barely reaches Windsor and Detroit—presumably to protect the Detroit stations.
It is technically considered by the CRTC as Windsor but it really isn't. It's about 65km/an hour drive time away. Truth be told CIII-TV-29 from Sarnia/Oil Springs comes in stronger I find in the evenings, even though its 90km away and has to go over Lake St. Claire.

Re: CIII-TV-22, this doesn't look good for those in Windsor who want to pull in the station

Quote:

The Post-Transition associated allotment is CIII-PT-22 at 600 kWh 10m, also on CH22. Canwest proposes to "flash cut" the NTSC operation at the end of Transition. It is proposed to operate at a power level well below the allotment power, in order to substantially reproduce existing analog coverage, and to avoid excessive signal into Detroit, since the American broadcasters serving that market have programming rights for some of the same programs broadcast on the Stevenson station. The proposed operation will operate on CH22 at parameters of 49 kW ERP /110 m EHAAT, using the existing antenna/feed system.
Also, the compareative contours that are attached in the link Emerald_Boar posted looks HORRIBLE for those in Chatham. They are going to lose their Grade B signal of CIII-TV-22 outright.

Also, Shaw says they intend to kill the analog signal of CIII-TV-22 on the August 31. But no where does it say if it will actually be able to go through with converting to digital on that day.

DigitalRocks 2011-03-18 04:31 PM

RF 22
 
Well there you have it... they have to broadcast lower due to american stations on the same RF. I'd imagine one of them being WNEM CBS in Flint. I pick it up on occasion with some tropo coming from the north, it will kick out Global 22.
Makes sense really.
