For me I got lots of seatack and I ws able to see the tropo build as this site when it got good I did a scan.

without the preamp installed i could pull in a few more channels by manually selecting it...like king, kcts,kstw and such..but still couldnt get civt...

I'm with you. Picked up KOIN-HD on my pre-amped 4228.

With a north facing 4-bay UHF reflector that I use only for Mt. Seymour stations and additionally with a huge cedar tree between it and SeaTac stations I was seeing elevated signal on most of the digital carriers that made it through from the south - usually there is not much to detect from SeaTac on that antenna! :D

In the days ahead the two Canadian analogue VHF-HI blowtorch stations in the area (CHAN Global channel 8 on Mt. Seymour and CKVU Citytv channel 10 on Saltspring Island) will at long last be going dark:

This means that anyone in the B.C. Lower Mainland, on the southeast side of Vancouver Island, and in Northwest Washington will suddenly be free of massive Adjacent Channel Interference on the VHF-HI band that tends to hit KCTS PBS channel 9 and KSTW CW channel 11 quite hard.

Please let us know in your local reception thread whether you see a difference after those Canadian flamethrowers go dark. :)

Stampeder, I am not up to speed on whether CHAN and CKVU will be moving their digital broadcasts to VHF-HI or staying with their current UHF designations. Also, will CBC be moving down from 58 to 43 at long last?

Safe to say that from Vancouver and Victoria there will be no more VHF-HI. I'll update the other thread found in that link.

I just noticed that RF19 (channel 24 KBCB) has now added a 720p 16:9 main channel. At present it is showing the following:

* 24.1 KBCB 720p
* 24.2 Estrella 480i
* 24.3 KBCB 480i

My guess is that they are going to dump 28.1 KBTC (PBS) onto the 24.1 720p channel, after RF27 CKVU in Victoria fires up tomorrow and causes co-channel interference problems from the originating RF27 KBTC signal.

I noticed the same thing this afternoon. The NBC Shopping Channel was showing up on both 24.1 and 24.3. KBTC has indicated they will be going back to the PBS only sub channel as of September 1st.

Now that CIVT-DT has moved from 33 to 32 you may want to scan 33 for KWPX the ION affiliate from Seattle before CKVU signs on channel 33. I am able to get direct reception of KWPX on channel 33 in Bellingham and immagine that some people in the lower mainland may be able to do the same now. (33.1 = ION HD, 33.2 = Quibo SD, and 33.3 ION Life SD).

In fact I noticed ION starting to come in while my antenna pointed NORTH at Vancouver, so I immagine that I was probably taking a lot of co-channel interference from KWPX on CIVT-DT when it was on channel 33.

I hope that CKVU will have a much stronger signal than CIVT did because there's going to be a lot of co-channel interference from Seattle on channel 33. ION is booming right in here nice and strong in Bellingham and I immagine also for some in the lower mainland. My receivers have no trouble getting a lock on ION right now.

It's too bad that CKVU had to go and co-locate itself on channel 33 (Vancouver) and channel 27 (Victoria) with channels in Seattle (KWPX 33) and Tacoma (KBTC 27). Co-channel interference from the United States will cause difficulties for their Canadian viewers, and interference from CKVU will cause difficulties for viewers in the United States. It would have been better for everybody if they had just flashcut channel 10, or if they really wanted two UHF channels -- channels 15 and 36 would have been better choices than 33 and 27.

It's too bad that CKVU had to go and co-locate itself on channel 33 (Vancouver) and channel 27 (Victoria) with channels in Seattle (KWPX 33) and Tacoma (KBTC 27).

At least we have a rebroadcast of KBTC on channel 24 (RF) from Bellingham, nothing for ION sadly.

Until CKVU fires-up channel 27 in Victoria and kills KBTC's OTA signal on Mt. Constitution.

The Mt. Constitution transmitter is on channel 24, remapping to 28.1 so it will not be affected by CKVU on 27, have a look at: http://en.wikipedia.org/wiki/KBTC-TV

The Mt. Constitution transmitter is on channel 24, remapping to 28.1 so it will not be affected by CKVU on 27, have a look at: http://en.wikipedia.org/wiki/KBTC-TV

But KBTC's main signal is on 27, and they're picking it up off the air to retransmit on channel 24.

Yes it will be affected because rf 27 is the signal from tacoma to bellingham for kbtc so bellingham receiver gets garbled by the new 27 in victoria. they will put the main channel on kbcb sub until they find another way to deliver the channel to orca island (bellingham)

KBTC sends its signal to ttansmitter via ota on 27 so it will be affected.
On KBCB 19.1 they have made 720 hd availible for the primary KBTC PBS until a solution is worked out.

I didn't realize the re-transmitter pulled KBTC OTA, I wonder how the FCC allowed IC to allocate CKVU to 27 then?

It'll be a downer in our household if we lose 33.2 QUBO. We've got a couple months left on our SHAW 'deal' and then we'll lose Treehouse. QUBO is very close in its programming (although regularly repeats reading out the same annoying 'audience provided' letters about it being a 'safe place for children, etc, etc ...).

What is the ERP of CKVU 33? It's coming in here at about 70% (about the same as it was before), and my ION reception is gone. :(

Co-channel interference is still a concern for me. KWPX is approved by the FCC to increase power on channel 33 from 179 to 400 kW ERP. Their CP expires on December 2nd 2011.

It would be great for me if KBTC was a sub channel of KBCB.

KBCB is the only Bellingham channel I can receive in PoMo and the shopping is becoming a bit of a drag. ;) Because of multipath I can't get KVOS consistently and K24IT-D (KBTC) only comes in one a blue moon.

This shouldn't be much of a surprise but I'm confused. Some are talking about a loss of KBTC 33.1-3 due to Canadian interference. Has this happened now? When I reposition my antenna towards Seatac and rescan - I still get those channels (I wanted to confirm whether or not Qubo would still be around for my daughters when we cut cable again in a couple months).

What am I supposed to be seeing at 33.1?
