Got a speedy reply to my question from the good folks at CFCN engineering.

They had a part failure this morning. replacement parts are on overnight order, and they expect to be back on air tomorrow.

(If the CFCN engineers read this forum - thanks again)

and I dont have to go crawling into my attic (ugghh)

Thanks for the update. Did they mention which part was affected by the failure?

"An electronic card in the transmit chain" :confused:
I have no idea what that is, but then I'm not a broadcast engineer. its generic enough to tell me some modular card in some piece of equipment failed. I work in the IT field, and so can picture a PCI card in a PC failing, or a card in a networking switch failing - so I would guess (and I'm really just guessing) that some of the broadcast equipment is constructed in a similar modular fashion, and one the cards failed.

They've ordered the part express overnight, and I'm sure they'll have it back up soon.

An electronic card in the transmit chainWell, if any part in the chain is going to fail the broadcast engineers hope it will be a swappable card and not something up top on the tower! :D

They use rack mounted gear similar to an IT server room. You can see some terrific photos of TX gear in the following thread:

TV Broadcast Towers & Transmitters (photos, vids) (http://www.digitalhome.ca/forum/showthread.php?t=114203)

Well, they're back on the air.
And you can totally tell where the replacement part came from: The station now appears as CIVT-DT 32-1! (Vancouver)
That'll confuse a few people. ;)

my TV still shows 4-1 CFCN-DT, although I didn't rescan.
didn't check my other TV or DVD recorders. maybe if I wait long enough I wont have too :)

anyways, I can happily confirm I have CTV again.

(OK, so technically I could've gone back to using the analog signal, but once you get used to the HD, it's very hard to go back, as I'm sure most on here would agree)

I wrote to CFCN engineering to let them know about the channel mapping issue. They wrote back to say the problem has now been corrected.

Nice to be back here again and see all the new posts,anyone know off hand if another channel is going digital soon? it sure be nice to see CBC get on the bandwagon and watch Hockey Night in Canada Saturday evenings OTA.Anyone heard anything?

Yes. Please see these previous messages, starting here:

Test transmissions for the new higher powered CFCN-DT Channel 29 service are expected to begin around the beginning of May 2011 - just in from my CTV contact.

CITY TV in Edmonton analog Channel 51 is off the air as of last night.

It is working for me right now from 23rd ave and 99th street.

But is analog CKEM 51 working? I think that was the problem Mike FM was reporting …

I'm looking at the spectrum analyzer right now.
17-DT is there
47-DT is there
45-analog is there
but there is no 51.

Analog channel 51 is gone. That's fine with me, the digital signal is nice and strong.

It's too bad CFRN digital didn't get up and running before the SuperBowl. Missed opportunity to make a splash.

hehe oops my bad! I wonder if anyone noticed. (anyone outside this board I'm meaning)

Perhaps it's time for someone to call Citytv Edmonton to let them know …

They are back on the air.

Oh? And here I thought they were shutting down the analog early and did this on purpose. :confused:

Just heard that the 1.5 Kwatt DTV transmitter is expected to arrive at the Calgary station site any day now ready for installation of the transitional service. The other detail is that a second 10 Kwatt transmitter has also been ordered for installation in 2012 for the new full power service.
This will translate to an ERP of > 100 Kwatts (possibly closer to 200 Kwatts). Great news for Southern Albertans! :)

Haven't heard anything official about the Full Power Service parameters yet.
