5.1 - 90 to 100%
7.1 - 90 to 100%
9.1 - 70 to 90%
11.1 - 100%
26.1 - 70 to 90%
32.1 - 70 to 80%
38.1 - 90 to 100%
44.1 - 80%
50.1 - 80 to 100%
60.1 - 80%
62.1 - 40 to 50%
66.1 - 60%
And of course absolutely no signal for 2.1 WBBM
Why did all my other signals increase with the booster except 2.1?
I'm on a mission now!
I wrote a huge list of what could be the problem. Only getting 20 hours of sleep this week due to working severe weather (I'm a meteorologist at NIU out in DeKalb) has made my brain turn to mush. But one brain cell finally woke up long enough to make me realize exactly what the problem is.
You live in Gilberts! You live at the home to WHYY-FM (103.9). Oh sure, it says they're in Dundee, but that's the town they serve. The actual 3,000 watt blowtorch that's killing you is the ~300' tower that's right behind the baseball diamond just north of 72 and on the west side of the railroad tracks. Those two devil's pitchfork thingy's sticking out of the west side near the top of the tower is their antenna. FM stations less than 5 miles away can and usually do interfere like crazy with channels 2-6. Your amp does have a variable FM attenuator. You need to make sure it is set so that it filters out FM signals. It quite possibly may be letting FM signals in fully. If it is, not only are you getting nuked by 103.9, but the amp is making things even worse!
Now, if you have the attenuation on at maximum, then you need a second FM trap, like one person in Gilberts needed that I helped a year or two ago.
They used to sell them at Radio Shack for $5; alas, they no longer do. They have them at Tri State Electronic up near Arlington Heights (http://www.tselectronic.com
), or you can grab one online from them:https://www.tselectronic.com/winegard/ft7500.html
I bet if you had an analog TV, channel 2 would just be loaded with interference. Make sure the trap is "in", or perhaps the knob or screw turned all the way to the right on your current amplifier, before you try this. See if that helps, then report back.
Just out of curiosity, try punching in these channels if you can do so manually (on most TV's, you have to scan for a channel or it won't let you tune it):
These are all Rockford stations. Let me know what you get, and we'll take it from there. BTW, that Radio Shack amp isn't very good. A better one at slightly more cost can be had at http://www.warrenelectronics.com/antennas/7777.htm
I order through them, and this amp is considered one of the best consumer-grade ones out there. I know, I own one and have installed several.
