Nothing really on the forum here regarding this type of signal interference yet. Here's what is happening now here..
A new wind farm consisting of up to a couple dozen turbines was built near here over the summer. It's looks nearly complete now in south central Essex county. The nearest turbines are about 3 miles away from me in the direction of Detroit (West and North west). Almost constant reception problems have developed nearly overnight within the last 3-4 weeks in the form of repetitive digital dropouts. Before this, Detroit UHF OTA reception was never ever this bad, even in strong winds.
Here is what I am seeing so far:
Channels most affected are UHF 60(/A\),44(CBS),43(PBS),45(NBC). More on this below. The cause is dead clear and unmistakable on analog CHWI-TV60 /A\ television repeater station broadcasting from downtown Windsor. There is a constant process of pulsing reception where the picture goes from good with colour to the loss of nearly all colour and more snowy then back again in exact intervals depending on the moving speed of the turbine blades. Looks as if someone is waving some steel mesh back and forth in front of my antenna. Also tested and replicated the same thing on two other temporary outdoor antenna setups and tuners I have tried in different areas in past days/weeks.
WWJ CBS is the most damaged of all the digital stations. It's signal is now very erratic/not reliable when there is any speed of wind even if it is light. Investigating on RF44 in NTSC mode, WWJ's amount of digital snow radically changes back and forth in it's "thickness". In digital this is causing my TV's (LN32A550 LCD) signal strength bars to go from 10/10 to 0/10 and back and all points in between. WWJ was always a good reliable station (when pointing at it) since I started watching OTA digital channels, until now.
I am quite upset about this!
The moment i learned turbines can and do screw up your TV reception, I was against them from that point on. Still... they were approved and were built quickly. Sure have been dreading the effects over the last month or so as they neared completion leading to an eventual uncorrectable,unavoidable multipath disaster. A damn shame that they are sitting directly in line with our only 24/7 reliable U.S TV market to boot. Bet someone with a good TV signal analyzer would have better proof of the damage these things are causing here. I can't be alone in seeing these new issues...anybody else in and around this specific area in southeastern Essex county area suddenly experiencing anything like what I have described over the last two weeks+?
I took a photo a last Wednesday afternoon from a high location up in a tree 50-55ft above ground on our small property here. The photo was taken looking towards the WNW-NW. Doesn't look like much, but the turbines pictured are the *the* ones in line with Detroit causing major problems.
Further reception details
-CHWI-TV60: Horrible reception started around the second week of Aug. Affected essentially 24 hrs a day now. Constant pulsing pattern is obvious of turbine blades slicing it up.
-CBEFT-TV54 (SRC): Slight noticable pattern visible especially in any red coloured content.
-W33BY(aka WHPR-TV33): Pulsing pattern visible in the already very poor b/w reception.
-WWJ-dt44 (62-1): Very unstable with extreme swings in signal readings leading to frequent to even constant dropouts. Slightly better near ground level but radical swings still exist.
-WTVS-dt43 (56-1): Second worse. Close behind WWJ for "dropout city".
-WDWO-dt18 (18-1): Third worse. Was already very weak before, now it's totalled.
-WDIV-dt45 (4-1): Can be bad at times, but far better than previous two.
-WMYD-dt21 (20-1): Not real bad, but station very hard to get now off axis.
-WKBD-dt14 (50-1): Very slight effects. There are a couple audio only dropouts noted from time to time though.
-WADL-dt39 (38-1): Worse when pointing NW. Facing nearly due north produces best result.
-WXYZ-dt41 (7-1): Was and still is Detroit's most reliable. Highest signal of all almost always.
-WJBK-dt07 (2-1): Continued great reception. No real changes noticed.
These problems ease off almost completely with times of dead calm wind, but don't necessarily stop 100%. Most times wind isn't as calm ~450ft up in turbine land.
This evening (Sep 13) in the moderate wind, the top 4 digitals listed are absolutely destroyed and unwatchable.. it's that bad.

NOTE: My main antenna is a Winegard hd7084p combo antenna mounted at 26 feet with a CM7777 preamp (since 2008) + near the coordinates of 42.097 -82.61. Up to date TVFOOL infromation/azimuth's are available in the album in my user profile.
