Good setup flavoie.
I see that WNYF (real channel 18) does not appear on your TVFool analysis. That means TVFool is "fool" in your case. In my case, I get different TVFool analyses, depending on if I provide my full address, my Lat and Long (from google earth) or using the zoom option from TVFool map analysis.

Like you I get WNPI, WCFE and WNYF (WNYF only at night) and all the local channels from my setup in the attic. I finally (yesterday) setup a CM2221HD with CM7777 on the peak of my roof (~35ft). With this setup all my local channels are at 100% Q, which completely masked WNPI and WNYF (cannot get them). Therefore, I slightly attenuated the signal by using a 2-way splitter and a roll of 150ft RG6 coax cable (this is what I have at hand now), and voila was able to pull WNYF and WNPI (but still only at night). My objective is to be able to get WNYF during the daytime, not only at night. Seing that you are able to do that is giving me hope that I may be able to get it during the day. I think I may not need the CM7777 preamp...
You are not too far from me, and I get WNPI, WCFE and WNYF along with all the other digital and analogue channels solid all day long. Check this thread for me results, but I have a tower, the cm4228, cm long range antenna, cm7777

lima, i always forget to ask, how are your antennas combined ? Is the 4228 on the UHF input and your other CM antenna on the VHF side of the cm7777 ?

lima, I'm wondering if you tried your CM2228hd to see if you can pull abc (virtual 50.1) and CW (virtual 50.2). I know that you have a deep fringe antenna that you may be using for this reception; I just want to see if it is possible to get at least a glimse of it with CM antennas 2221(mod) and 2228hd. I'm planning to construct a special high gain antenna for that purpose. I have already tested my special antenna in my attic and was able to get the weaker WNYF (nights only). Also I was able to get abc, CW and WPBS during tropo times with another antenna (GH10) in the attic.

Flavoie....that is how it is

Skipticum....I have the cm4228 not the 4228hd. It's UHF only and hi-def. I do get abc and cw depending on where I point the antennas. cbs has been very clear of late, just like my omni 1 and 2 HD, along with my 6 pbs channels 18.1,2,3 and 53.1,2.3

I think you mean 57.1,2,3, not 53.

My setup is rewired now. I still get WNYF, although just this morning I saw it drop to SNR 16 on my 950Q. It's currently at SNR 18.5 as of 12:05pm.

The SNR is good late at night and early morning. On my 950Q the SNR is between 19.5 and 24 at night and early morning. It drops to 16.5 for the rest of the day.

Can I ask about your ANT751 ?

Q1 ) where and how do you have it mounted ?
Q2) do you have to swivel it or point it do get certain channels ? I've noticed that the CITY and CBC towers are in totally different directions ..
Q3) Do you use an amplifier or other gear with the ANT751 ?

Thanks, John.

I made a small change to my CM7777 (terminated the VHF port), and I noticed my reception improved dramatically, especially for the weak channels (WNYF, with SNR of 26/27). I used to use a variable attenuator to tune in WNYF, and after the change to the pre-amp, I no longer need it. Also, I was able to tune in abc (50.1), CW (50.2) and WPBS (16.1, 2, and 3).

The factory setting for CM7777 supposed to be default set to "combined" and FM trap st to "in". But when I opened the box of cm7777, I found it set to VHF separate. I left at VHF separate and terminated the port.

Did we have a tropo effect last night? I'm just trying to see if the improvement in my reception is real.

nice results ! I think my 7777 factory setting was Separates as well even though I expected it to be Combined. Trap was In. So I didn't change anything since I was connecting 2 antennas to the 7777.

So I finally rewired the side of the house - a part that hadn't been finished yet. Pics here.

I'm hoping the change to an all-Quad shield run will help. I had Quad only outside up until last week. Many will say it doesn't matter. At least I won't wonder if I did everything I could have :)

I tried using a 2:1 splitter in the house; it decreases my SNR level reading on my 950Q by 1. (WNYF goes from 22/23 to 21/22)
I'll keep it there, this way I don't have to use an A/B switch to switch between my production system (HVR1600+1800, to be replaced by a single 2250) and my 950Q I use for testing.

After two days of observation (two rainy/snowy days), now I can confirm that my setup is optimum and the fantastic improvement in my reception is real (as per post # 369).

flavoie, I'm wondering if you have tried to tune in abc (50.1) and CW (50.2) with your setup, since you have a rotor with your CM4228HD. I initially had two objectives with my ota hoby; one is to get wnyf reliably, even during the day, and sofar seems I have achieved that (with the outdoor mounted CM4221hd). The other is to get abc and cw (50.1 and 50.2) reliably at night. I'm still trying to see if I need a deep fringe antenna or a common antenna, such as the CM4228hd. If you could give your rotor a try and swing the CM4228hd a bit west and see if you can catch a glimpse of abc and cw.

In a previous post lima mentioned that he can reliably get abc and cw, but I wasn't sure if that was achieved with his long range antenna or the CM4228.

Even though lima20's results aren't exactly very clear, and I unfortunately never been blessed to see his TVFool results, he did acknowledge when I was asking that he's using his 4228 original for UHF and his other CM antenna for VHF, and both are mixed in using the cm7777.

So lima20 is getting WWTI 50.1/2 (ABC/CW) but we don't know when he's getting it and whether he's got the capability to know if he loses it during the day. On the other hand, his 4228 does have better gain on channel 50 than my 4228hd.

The couple of times I moved the rotor toward Watertown with my 4228hd and scanned specifically just channel 50, I did not get something showing up. My WinTV software would usually at least show the new channel if it found something. But I will try again. It will need to be at night for sure...

Did you scan for 21 or 50? WWTI is on RF 21.

tvlurker is right. The real channel is 21 for WWTI. Also, I may add that last week I was able to get WWTI and WPBS with my CM4221hd pointing to the WNYF transmitter, but that was at a mild tropo night. That gives me hope that may be getting WWTI on regular basis is not far fetched...

Can't remember if i scanned 21 or 50, this could well explain it... Very good point...

I just rescanned 21 (remotely controling my home PC using vnc) while pointed at WNYF. Nothing. I have remote access to the software, but not the rotor interface... So I will rotate to WWTI sometime this week to try it out again.

Watertown and South Colton are only 30 degrees from each other in Orleans -- I don't know how much of a difference that would make on a 4221. (Although for tropo, every fraction of a dB counts.)

rotated 30 degrees, same results. WWTI, channel 21 (50.1) won't show in scan. What may not help are strong 20 and 22 signals off the back (CF), but 17 off the front (HC)never stopped me from getting WNYF(18 real), and 17 is one of my highest SNR signals...

21 won't get better for those near Herberts Corners.

20 and 22 will be moving to Herberts Corners next summer.

CBOFT will revert to 9 at Camp Fortune, CHCH will flash cut to 22 at Herberts Corners, and CJMT will switch from out-of-core channel 66 to 20 at Herberts Corners.

By the way, 17 is only 5 kW.
