sounds to me like u may have sumthin else goin on there??

Measured Signal Strength
-12 dBmV -> ~ -61 dBm (in a 75 ohm system)

Pretty stout signal, doesn't look like a noise limited system to me.
Maybe try adding fixed attenuation in line, in a truly noise limited system, the SNR should decrease with the added attenuation. If it doesn't change at all with the fixed attenuation, you know for sure something else is going on (my guess is it won't change much).

The 11.1 is also out of band for the DB8, and there is a distribution amp as well, adding to noise ( 3 TVs 5 PVR tuners ).
Its all set up for buffalo only. I'm going to make some changes once the dust settles after Aug 31. Just posting signal strength for FYI, and I'm not expecting good results from the DB8 for 11.1 .

Been lurking here for awhile. Given everyone's horror stories, I wasn't expecting to be able to pick up this channel still, given that my antenna is a little indoor Terk HDTVI (unamplified). I am on the tenth floor facing westwards, near Eglinton & Marlee. The antenna is two feet from the window, and facing north west - lots of high rises here and my best signals are actually bounced off anther building. To my surprise, I pick up CHCH easily, with a signal of about 56%, which is about as good as I usually get on any channel. I was looking into a small outdoor antenna to use indoors to see if I can possibly get some more of the US channels, but given that my little Terk is hauling in 16 channels, I think I might wait for all the dust to settle from the conversion before making a firm decision.

Signal testing at night is unreliable. Try again during the afternoon.

Again, trying to receive CHCH here is Mississauga with my ClearStream 2. The only way that I can reliably receive the signal is if I am attempting to adjust my antenna, which is attached to a room divider screen facing out my window. While I am touching the screen to adjust the direction of the antenna I receive the channel perfectly. The moment I release the screen, the signal is lost.

So, all I need to do is find someone to stand with their hand grasping the room divider screen in order to receive CH. Of course, they'll have to stand off to the side so as not to block the screen.

I believe this was the reason people had children before cable and satellite existed ;)

It was late afternoon when I rescanned and picked up sixteen channels (up from eleven). I tested them throughout the evening too. Still getting most of them this morning except WUTV. CHCH still a solid 55%. TVO has actually been a bit more temperamental for me than CHCH - I have to reposition my antenna a bit more to the south to get that one, which means I lose CITY.

That and to change the channels if they didn't have a remote control.

Heh - noticed that when I was repositioning the Terk that my signal shot up to 88% on CHCH when I was holding it. Thanks for the info on the Clearstream 2 - it was one of two I was considering as a replacement for the Terk.

Just noticed areound 8:00am my signal went from mid-60s to 0. Several minutes later, it was back in the mid-60s, maybe a touch higher?? I was getting occasional pixelation before, but seems good now (I know, very small sample).

Perhaps this was some sort of transmitter adjustment? :confused:

Now has a note about re-scanning (good!) and dates for London (Aug. 22) and Muskoka (Aug. 24).

I think it would have been a good idea in their PSAs and website to mention the UHF 18 station was temporary and that they'd be reverting to VHF in Hamilton, and people with UHF-only antennas might need to do something to retain the signal. I don't think the average OTA viewer understands this.

No idea if they had it there before as I've never visited their website until now, but noticed they have links to the post transition coverage contours for each of their 4 transmitter locations near the bottom of the page. 60 dBu and 36 dBu contours are shown to help determine if you are in the coverage area, and to what degree. I am just outside the 36 dBu contour.

Picking up CHCH with a YA1713 pointed at WBBZ.
CHCH coming in at 26-27 snr
WBBZ coming in at 19-20 snr
Both channels no errors
I am located in Scarborough

Damn...looks like I have to get one - YA 1713.

I hope there is a thread on how to get VHF channels for those of us on the east side.

I did another scan on my TV and yesterday CHCH was awesome and today I got nothing on 11-1. Why can't I get it anymore?

Tropo conditions most likely

We just had our huge spruce tree cut down which was blocking everything from the rear of my 4228hd (which is aiming at Hamilton) so I was expecting a big increase in signal strength at least.

where are you relative to the service contours? See ElGranChico's post for their website.
Are you using a VHF antenna?
Do you have a UVSJ and / or CH 11 trap in line possibly blocking VHF HI?

I'm outside of it, but do have an old vhf antenna.
It's been pretty much nighttime only for me since the transition.
I might be able to improve it here as others have with a new VHF antenna.
Won't know for sure though till I try.

Hello Kooguy,

As I mentioned back on this thread the one of the main downsides of the DTV transition is on the receiving end and your antennas capability to receive the higher VHF band.

First off I am not sure just what type of antenna setup you have? I know this is a little late for this but here is a small tip that might give idea if you are going to require a separated antenna for the stations in upper VHF band.

Here’s what I did, prior to the switchover and can still be performed on the channels that have not switch over yet. Using the antenna setup you presently or using (UHF), tune the TV receiver or tuners etc to the NTSC signal old analog. If you can pick up that signal there is a good chance you will be able to pick the digital signal. So far it work has work f for me, prior to the switchover I tested the older 4228 on channels 7, 9, 11.

So far it has worked for me checkout channel 9 analog with your antenna before the shut down the analog signal. They have a pretty strong VHF analog signal most likely your uhf and with still pick it up. If doesn’t well you most likely have to get another antenna.

BTW there are some tricks to increase the uhf antennas performance in the higher vhf band, but they are limited. I agree with you, no matter wait for the dust to settles. I am sure there is more fun yet to come :o

All the best!

I just looked at this map
CHCH Hamilton Map (http://www.chchnews.ca/CHCH-TV-0-HAMILTON.jpg) and I am in Beamsville which is in the first inner circle. I have the 4228hd wich is VHF-hi and UHF. I am using the 7777 pre amp which has an FM trap setting I can't remember if I had it set to in or out bit I think it's set to in, is that good?
