Since SUN tv is going to shutdown OTA its not to late for CFTO to stay on frequency 40 and increase power to 100kw.A much better option that going back to 9.

I still think I might have issues here getting CFTO/CTV Post transition on VHF Ch 9. Similar to Canadians with WNGS on VHF 7. It does have a much higher rad center going for it, but it will still have to clear the Niagara Escarpment and then some to get to me. We'll have to wait and see what next year brings.

Yep, I agree, nice to see it explained in plain english.

I say that because even the existing UHF doesn't get here, just barely on extreme tropo days, think I saw it like twice all summer long. We'll have to wait and see what next year brings.

You're right, you'll have to wait and see.

On the one hand, channel 9 will propagate over the escarpment better than channel 40, because VHF signals can (generally) bend over obstructions better than UHF can.

On the other hand, in the extreme fringes of a VHF-High stations, you will be more susceptible to interference from nearby FM broadcast station 2nd harmonics - either generated at the transmitter (in Canada only restricted to 80 dB down from the primary signal, I'm not familiar with the FCC rules) or at your receiver or preamp.

To mitigate FM interference, try a highly directional VHF antenna (to avoid local FM signals) with an FM trap (to attenuate the ones you can't avoid.

Of course, if there are no local high power signals between 93 and 96 MHz (half of channel 9's 186 to 192 MHz channel), this may not be a problem for you. (But it looks like you have at least one 100 kW station (WNED) and two 47 kW stations near Buffalo in the 93-96 range.)

Two other thoughts. A VHF-HI antenna will also help as it won't receive FM as well as a full VHF antenna. Secondly, with most FM traps, the filtering starts to drop off below about 100MHz to avoid interfering with Channel 6. To overcome this you can either get a full band FM trap that doesn't protect channel 6 or just get an HLSJ that will filter out VHF-LO as well.

Another option is to use an FM notch filter to just filter out problem FM stations. Some preamps have a variable notch filter built in.

True, but tuning the notch isn't very easy for the average person. You could buy notches that have been pre-tuned, but they can be quite expensive.

If you're very close to an FM broadcaster, and you're trying to get a distant digital TV station, you also want to have a directional antenna that will avoid picking up FM transmitter generated second harmonics. The FM notch filter won't help with those.

Agreed, special equipment is often necessary. OTOH, it can be done using an FM tuner or TV by tuning it until interference from the strong station is minimized.

The FM notch filter won't help with those.
That depends on where the harmonics are being generated. If it's from the station, it won't help. If it's in the preamp or tuner, it will.

The following CTV-owned OTA digital television stations have been added to Stampeder's mirror of the Industry Canada database (http://www.user.dccnet.com/jonleblanc/Canada_TV_Stations/DT.html). They are listed as having been approved by the CRTC.

Charlottetown; Ch. 8; CKCW-DT-1; 461605 lat; 632027 long; 150.3 metres; 9,600 watts
Wheatley; Ch. 16; CHWI-DT; 420830 lat; 822648 long; 168.2 metres; 3,400 watts
Lethbridge; Ch. 13; CFCN-DT-5; 494359 lat; 1125740 long; 171.5 metres; 27,000 watts
Victoria; Ch. 23; CIVI-DT; 482530 lat; 1232013 long; 99.6 metres; 1,500 watts

Wow, that "superstation" should reach all the way to the city limits. :rolleyes:

I believe that's an error. The CIVT allotment shows 15k watts ERP. Not 1.5k.

The allotment is for 15 kW, but they appear to have applied/been approved for 1.5 kW — according to the database, anyway.

CHWI but no CFPL yet?

Nor CHRO or CKVR. My guess is there will be hearings for those stations for some reason (likely due to changes in parameters).

In the case of CKVR, hopefully a hearing to oversee an increase in ERP.

CHRO-DT-43 (A Ottawa) now shows up as AP (approved by CRTC) in Industry Canada's database. See stampeder's list:

CKCO-DT Kitchener's entry in the IC Database changed from AP (Approved by CRTC) to AU (Authorized By Industry Canada) on Oct. 29, so if anyone hears anything from them about their latest transition status please let us know.ON Kitchener AU 13 CKCO-DT 432415 803804 291.9 12000 210.00

Well, if that means that CTV is clear to start testing a digital signal on that VHF station to prove out that they can...well I'm ready with an antenna pointed right at them...and getting a clear analog signal. I'm looking forward to see what I can catch in digital.

Is going from AP to AU a step forward or backward? I noticed the same thing for CITY woodstock and OMNI1 london. Both originally said AP and now they read AU. Could someone please explain the difference between the two?

Same here in London!
