CIRI - Calgary Traffic Advisory Radio 106.5

C

CKNF

Was to go dark after the 106.7 CKYR test period was completed on March 1st. It's now almost mid-July and they're still on the air. Both stations seem to be able to co-exist on adjacent frequencies without any real difficulty tuning either one. However, this goes against any operating practice I've ever seen in Canada.

For several months now we've had two licensed stations co-exist on adjacent frequencies and I'm wondering if this could set some kind of a new precedent for lower powered FM stations here?

From what I understand, 106.5 shouldn't still be on the air, however, I can't really imagine the City of Calgary blatantly defying federal orders.

Has anyone else ever seen something like this happen before?

It is my understanding that in some U.S. cities, there are at least two low-power stations transmitting on the same frequency or on adjacent frequencies. There is also a group of maybe 6 such stations in Mexico City too, though they are all under the same ownership (a university).
 
Noncommercial stations in the U.S. are licensed on a contour-protection basis. If you can demonstrate that a 100-watt station (the lowest power currently licensed for a "full-power" signal) doesn't create interference to another 100-watt station on 88.3, both can be licensed. In Chicago, for instance, the sprawl of the city has allowed for such low-power stations to indeed coexist in various parts of town on 88.1 (two of them at opposite ends of town), 88.3 (also two, at opposite ends), 88.5, 88.7 and 88.9.

Canada also licenses stations on a contour-protection basis, but I'm pretty sure that doesn't allow for 106.5 and 106.7 to coexist right in Calgary. If memory serves, CIRI is a non-protected station and must now seek a new frequency. It'll get settled, sooner or later. They won't both stay where they are.
 
CIRI 106.5 is listed on the Industry Canada database as a "tentative deletion". I just can't see them allowing CIRI to operate much longer adjacent to the 8,000 watt CKYR on 106.7. Perhaps things were put on hold due to the recent flooding in Calgary as I would assume CIRI provided emergency programming during the crisis.
 
New Orleans had 2 stations (94.7 and 94.9) that co-existed for years without interfering with each other. Of course they both had the same programming, but you could easily separate one from the other.

I do have to say, that station came in handy a few times during the crisis in helping with navigating around all the road closures. What a mess it was that week. There were a couple of days where I just worked from home. Nobody wants to sit on the freeway for over 3 hours to get to a destination that would normally be a 20-25 minute drive.

Should be interesting to see what will eventually happen. I've listened to both stations for good chunks of time in the car just to see if one interferes with the other and from what I heard, neither station is causing the other any real grief other than the odd split second drop-out on 106.5. However, I would attribute that more to the fact that CIRI (106.5) is very low power because those dropouts were not unheard of before 106.7 signed on the air. Of course, that's with a car radio. On a portable, CIRI is a bit tougher to pick up, but it's still there without too much bleed through from 106.7. In regards to 106.7, no signal issues whatsoever. Nice clean signal...well, as good as you can expect from a 1500 watt station.
