Unhappy I lost my KOMU!

Hi, folks...

I have an issue.

I live in Fulton and I am using a RCA Compact Outdoor Yagi HDTV Antenna with an amplifier. Using the information on AntennaWeb, I aimed the antenna precisely in the middle of the signal directions. For years now, it's worked flawlessly, getting all the channels in the area just fine, save for the occasional hiccup during storms and sometimes in icy conditions, but that is expected.

Until yesterday. All of a sudden, I have stopped receiving KOMU/CW (8.1/8.3) totally. It says I have no signal. This baffles me, because I called KOMU and they said there is nothing wrong with their broadcast signal, yet while their station is not even coming in, I am able to get the three PBS stations (6.1/6.2/6.3), the three KRCG stations (13.1/13.2/13.3), the four KMIZ stations (17.1/17.2/17.3/17.4), Fox 22 (22.1) and KNLJ (25.1).

KOMU has always been the powerhouse station, the strongest signal out there, yet boom...nothing now. So please help me: Is there any way to get it back? I wouldn't think it's the antenna, because every other station is fine. Do I press KOMU on the issue? I want that station back!

Thank you.

Keep trying with them. I had some trouble with the KOMU signal last night too, during the first half of SNF. Couldn't tell for sure if it was an issue with KOMU or with the actual feed coming from Denver, but the signal periodically broke up then the screen went to black. It is coming in fine today though.

Just to rule anything else out, can you temporarily rotate the antenna to aim straight at KOMU and see if that causes the station to come in? KOMU does actually operate at the smallest power output of any Columbia-Jefferson City station and on the lowest frequency, which do combine to make them the most difficult digital signal to receive at much distance from the station. But since they've been the strongest for you in Fulton, that shouldn't be a factor.

I would also recommend checking all cable connections between the antenna and the TV, including at the antenna, any splice or splitter points, wall, and TV.

Are there any new devices in your home that might be interfering? Due to the low frequencies used, in our home we've found that activities such as turning a vacuum cleaner on or off, running the microwave, or even turning a fluorescent bulb on or off can temporarily interrupt being able to get KOMU and KRCG.

I aimed it as close as I could, and nothing.

I did, and I got nothing.

Here's the funny part...at one point KOMU did work for a while on both TV's I have. The smaller one worked instantly, but the other TV had to be reset. It only lasted about 15-20 minutes or so, because it has gone black again.

No, nothing new.

Now this you will find hard to believe, but I swear on everything good and holy that I am not lying. I affected the signal when I got too close to both TV's. I kid you not. My wife was making fun of me about it, LOL.

I guess I am going to have to. This makes zero sense...it has to be on their end. Not a single KOMU signal, but everything else is perfect. I am baffled.

KOMU has an application with the FCC to turn up their power. If they were already the strongest signal you had, and then they just turned up the power, the signal might actually be too strong and you're getting severe multipath. Do you have an amplifier of any sort? If so, does it work if you turn the amplifier down or off?

KOMU last changed their ERP several years ago. Most likely, today's issue is due to some new electrical interference or signal ingress.

What are you using for an amplifier?

That suggests signal ingress to me, perhaps due to a bad F-connector or similar.

Well, I checked out everything...ran the antenna without amplifier, with and all measures in between. Nothing worked.


Then all of a sudden, everything was fine and remains so. Oddness for sure. I am glad to get my station back!


Thanks for all the help and suggestions, folks!

Hi, folks...me again.

I swear I have the worst luck. After my above issues some time back, my television OTA reception was just fine. About a week ago, I lost stations...as in, only KOMU came in, with KRCG, PBS and KMIZ coming in occasionally and even then not totally clear. Now for the last two days I have had nothing. Noting but KOMU and KNLJ. That's it.

I tried waiting it out, but nothing seems to be happening. I checked how my antenna is pointed, and it's still firmly as it was, pointing toward the weaker KMIZ with KRCG and KOMU to each side as they are stronger. I then checked the signal booster, in case it went haywire. Nope, that didn't do it, either. Connections and cables are fine. I even reset my TV and ran an auto scan of channels, just in case. Nada.

I am at my wit's end. I have no idea what's going on. Hopefully it'll magically fix itself again, but man this is frustrating. Any ideas?

The heat and humidity are causing distant signals to cut in and interfere with the local ones. See http://www.dxinfocentre.com/tropo.html for predictions on which days will be especially bad. Here in Mid-MO most of our locals are lower power, even if not technically low-power stations like KQFX, and they're getting trampled on by more powerful distant stations on the same frequencies. On the flip side, it looks like today would be a great day to pick up Springfield stations... With a powerful antenna and perfect conditions, might even see Joplin, Fort Smith or even Tulsa.

It is very, very, very unlikely that out of market signals are causing reception issues with the local stations to anyone in Fulton.
