Here are the data from Stampeder's mirror of the IC database, which contains the proposed operating parameters for CJON-DT.

Code:
Prov	 City		Status	 Ch.	 Call sign	 Lat.	 Long.	 	HAAT	 HAGL	 Max ERP	Avg ERP	 Freq.	 
NF	 St. John's	RE	 21	 CJON-DT	 473132	 -524248	 254.6	 91.4	 266000	 	128400	 512.00	 
NF	 St. John's	OP	 6	 CJON-TV	 473136	 -524246	 250.1	 91.4	 212800	 	76000	 82.00	 +
Antenna height above ground level is the same for Channels 6 and 21.

Sparky2k, will CHCH be providing program guide data in its PSIP? There was some in the past but it's gone now.

OOPs, pgm info tables in stream from master control appear to be empty.
I'll get on to CH zero.
Thanks,

Prgm info would be nice on CHCH! If you could make this happen, I would be very appreciative!

CHEK-DT Application

Posted today by the CRTC
http://crtc.gc.ca/eng/archive/2011/2011-340.htm

Link to application:
https://services.crtc.gc.ca/pub/DocW...ppNo=201100859

My summary:
Channel 49 using the minimum amount of power possible to cover Victoria, Vancouver and Nanaimo (I assume to obtain simulsub).
They list their asset cost to transition at $460 k

The radio station is not at the top. It's a 10 or 12 bay antenna on the tower. It goes almost to the top, but not all the way. The TV antenna's are at the top.

I have a picture. It is not the clearest, but you get the idea. The FM is the dark "barrels" running most of the top half until the TV antennas take over at the top.

The FM is CHOZ-FM 94.7 on those bays. The channel 6 audio heard on FM radios is simply the audio coming from the TV transmitter.

As you can see with this configuration, such a tall FM antenna, they couldn't put TV below it.

CFTU Montreal post-transitional contours

From the application for CFTU-DT, posted to the CRTC website Friday.



LEGEND
Pink lines represent grade A and B contours for current analog Channel 29 @ 10,000 kW omnidirectional ERP.
Dotted and solid lines represent digital urban contour and noise-bounding limiting contour for approved DTV Channel 29 @ 450 watts directional max ERP.

Thanks for the pictures Wharfe, that makes sense. The new UHF antenna will be much smaller than the current channel 6 one, so if they wanted they could move the FM antenna even higher on the tower, but it probably wouldn't be worth the effort.

I understand about channel 6 audio. I wonder if no one is using channel 6 anywhere near by if they could apply for an FM license to transmit the TV audio on 87.7 MHz (or another frequency if there are any available) to keep listeners happy. It shouldn't cost that much and for various technical reasons, the sound quality would improve over receiving the NTSC audio.

I wondered that myself. If enough people rely on the 87.7 audio maybe they will setup a new transmitter for it after the switch.. There are plenty of open frequencies here. It would sound much better. Currently the audio is a lower volume than normal FM stations, and you can hear the video pilot tone!

Also, you can see that there are a couple more FM bays sitting above an ice sheild. Not sure if they are audio for NTV, or an aux FM antenna. If they're already transmitting audio on a separate transmitter/antenna then that makes it even easier.

Their FM signal is the strongest, most rock-solid in the whole market as it is. Definitely not much to "gain" from moving the FM antenna any higher!

Application for CFAP-DT Québec

The CRTC is accepting comments regarding the application for CFAP-DT Québec (V network).
https://services.crtc.gc.ca/pub/inst...PST=A&Lang=eng
Here are some specs translated from their technical brief:

Antenna pattern: Directionnel
ERP at beam-tilt:
Max.: 20.1 kW @ 0.5°
Avg.: 12.7 kW @ 0.5°
HAAT: 172.91 metres
Channel: 39 (620‐626 MHz)

Transmitter location is same as now, at Complexe G in downtown Quebec City. The station states it will need to be off the air at the transition deadline for a few days to dismantle its current Channel 2 antenna (analog service) to make room for its new slot antenna for Channel 39.

CFJP-DT Montreal and CFKM-DT Trois-Rivières

According to Stampeder's mirror of the Industry Canada database, the CRTC has approved the post-transitional parameters for two more V statuibs.

Montrėal; ch. 35; CFJP-DT(1); 453116 lat.; -733358 long; 79.1 m HAAT; 13750 watts omnidirectional
Trois-Rivières; ch. 34; CFKM-DT; 462927 lat.; -723858 long.; 395.7 m HAAT; 9000 watts max.; 3910 watts avg.

I noted your PSA points to CHCH customers losing analogue as of August 31st.

As plans firm up, maybe a tweak of the PSA on the conversion and transistion date for CH might help alleviate some confusion, keeping in mind the differing dates..... :-)

(there is some crossover here between this and the PSA thread unfortunately)

I think this is one of these situations where engineering and programming are not quite on the same page. It seems to me the PSA information was taken from Industry Canadas' playbook without being aware of the engineering dept conversion schedules.
BTW, we should now have our usual PSIP guide data, since last week some time.
Finally, we are going to be trying to locate the source of the transmitted ghost recently observed on CH 11, therefore both analog 11 and DTV 18 will be off air or at low power this Sunday night into Monday morn.

Does anyone know the status of CHEX-TV-2 Durham/Oshawa. Are they, or will they be converting to DTV come the end of August? I heard CHEX Peterboro will be transitioning sometime this year.
