I'd like to get KQMK-LD, physical channel 21, virtual 25. Please reference RabbitEars.Info . My working antenna (see complete setup below) is pointed to the NE and I am picking up physical channels (listed in order of field strength) 26, 29, 22, 20, 31, 12, 32, 17, 15, 33, and 35. Channel 21 has a field strength less than 33 and 35, and is in the same general direction. I thought I should be able to pick it up. However, when I look at fccdata.org the station is in a different location on the map: FCCdata.org - powered by REC

There are two locations in fccdata.org. The most recent matches with rabbitears.info, another site marked as pending shows the Ashland, NE location.

Sorry I don't know how to interpret FCC application data. Where is the station right now? To the NE or NW?

My antenna setup is on a 50-foot tower and clears the local terrain by around 15'. I have an RCA ANT3038XR pointed to the NE and a Five Star Yagi 2020 Antenna pointed to the SE. They are combined with a Wineguard CC-7870 and then into a Wineguard pre-amp on mast. Currently the cables from the antenna to the combiner are not correct, they are of different lengths and pretty sure the cable to the Five Star is damaged. As soon as the wind dies down around here I'm going to replace with equal length cables. I'd like to have an idea of where to point the Five Star when I'm up on the tower. The SE direction was intended to capture the Lincoln market but turns out I won't grab any networks I don't already have and there is competing physical channels, so I'm going to move it. At least I'll point it in the same direction as the RCA and get some gain. I could point to the NW if that's really where KQMK-LD is. I'll have my phone so I can re-scan my DVR while I'm on the tower to verify my channels.

Fairly new at this, any advice is appreciated.

I hadn't done a TV Fool report, I've only looked at the RabbitEars.info report. TV Fool is very helpful! It places the transmitter to the NW-ish, same as fccdata.org. It is 10.7 miles from me. Doing the NM calculation the value is 17.9. If the report is accurate, pointing my second antenna directly towards the transmitter should be sufficient. Looks like there are several more stations I should be able to pick up.

Since you asked about a TV Fool report I assume it's more accurate?

Hello, double16; welcome to the forum.

Thank you for the signal report; it helps.

The FCCdata.org shows two locations. The one dated 07/07/2020 lists the correct location which is:
Latitude: N 41° 13 ' 29.6 "
Longitude: W 95° 57 ' 10.5 "
or
41.224889, -95.952917

As a double check:
RabbitEars.Info
click on Application Info
Application Search Details
click on View LMS Information for License
click on View Engineering Data for coordinates and antenna data

It's to the NE and further away.
I have an RCA ANT3038XR pointed to the NE and a Five Star Yagi 2020 Antenna pointed to the SE. They are combined with a Wineguard CC-7870 and then into a Wineguard pre-amp on mast.
Combining two antennas aimed in different directions with a CC-7870 is the same as combining two antennas aimed in different directions with a splitter in reverse. It often doesn't work because when the same signals arrive at the combiner they will interfere with each other if they are not in phase (arrive at the same instant).

If you don't have all the signals when combined that you had when the antennas were separate, that method of combining doesn't work for your location.

I sugest you try just one antenna aimed at KQMK as a test.
Currently the cables from the antenna to the combiner are not correct, they are of different lengths..... As soon as the wind dies down around here I'm going to replace with equal length cables.
When the two antennas are aimed in different directions, the cables do not need to be equal length; it's irrelevant. They only need to be equal length when you combine two identical antennas aimed in the same direction for additional gain.
At least I'll point it in the same direction as the RCA and get some gain.
Not a good idea; let just one antenna do the job.

The TVFool reports used to be the most accurate, but they now contain many errors because they use a database that is not up to date.

Trip, a member of this forum, the webmaster for rabbitears.info and an employee of the FCC, saw that the TVFool reports were becoming less useful. He created the rabbitears.info Signal Search Map to generate more accurate reports.

I reviewed the tower map and terrain map in RabbitEars.info and I should be able to receive the station. I'm receiving 35 which has less strength and more distance and is in the same direction. So I'm puzzled why I don't currently get 21, or 27 for that matter. I'll take your advice and try with only the one antenna and bypassing the combiner and see what I get. Will report back when I'm able to get up the tower.

I looked at the Longley-Rice coverage maps for what I think is your location. The report moves the marker to protect your identity.

Since they are a computer simulation, the coverage maps aren't as accurate as implied, but KQMK shows light green. However, KQMK RF 21 is at 34.4 degrees and KHIN RF 35 is at 59.9 degrees. Antenna aim can make a difference.

I’m not sure exactly where the antenna is pointed. I used the Wineguard app to locate a tower with augmented reality and then eye-balled it. It wasn’t the 35 tower, it’s a rebroadcast of 33 so not necessary. Pretty sure it was the three close together with 17,22,31. I have access to a good compass and will use that to align antennas.

Still too windy to get on the tower. I did make a measurement from the ground and it's close to 40 degrees.

I also tried something for kicks and went to the top of the nearest hill and used a cheap DTV antenna in the attached picture on a cheap 13.3" TV. I got all the same channels I'm getting with my tower mounted RCA except for 12, and that's a VHF signal. Kinda surprised!

Maybe I'm putting too much on receiving channel 35. It's field strength is 57.54 and I'm picking it up on this cheap thing. Channel 21 and 27 have strengths 73.87 and 70.12, respectively. I think if I'm getting something in the same general direction at 57.54, I should get 73.87.

The application for KQMK-LD in Omaha was approved July 6th, 2020. What is the timing of licensing? Does it happen before the station is built? Seems reasonable. Perhaps KQMK-LD isn't transmitting yet?

I'm starting to think aiming at 40 degrees, where it currently is, is good enough and I'll point my second antenna according to my original plan, at 250 degrees towards Lincoln. Just doesn't seem like at this field strength 8.2 degrees will make a difference. (Too bad it wasn't such a pain to adjust it.) I will still re-scan with only the RCA connected and bypass the combiner to see what I get.

Thanks for answering my questions. I like to dig into stuff like this and try to understand.

I would think so too.

The rabbitears says it's on the air.
RabbitEars.Info

So, if your tuner isn't able to pick up KQMK, it's either too weak or not on the air.

The rabbitears.info site has monitoring stations that use SiliconDust HDHR tuners.
RabbitEars.Info
click on Sitemap
RabbitEars.Info
scroll down and click on
Maps > Live Bandscan
TV reception map
on right side scroll down to and click on
Bellevue, NE (about 3/4 down)
TV stations received at Bellevue, NE tuner0
on lower left scroll down to KQMK and click on graphs
Signal graphs for KQMK-LD at Bellevue, NE on tuner0

It looks like KQMK is on the air but very weak even in Bellevue. His antenna must not have much gain.

KHIN is stronger at his location.

After comparing the signal graphs for KQMK 21 and KHIN 35 done in Bellevue, it looks like KQMK is running at reduced power.

I wonder how you can contact the KQMK station engineer.

That's great info, thanks! I was at a relative's house last night about 2-3 miles away from the station and I was able to get a picture on 21, just to be sure it is on the air.

I wonder how you can contact the KQMK station engineer.
The FCC application has an email, which I'm sure isn't the station engineer, but it's a start.

Good; that seems to confirm it's at the new location in Omaha.

All I could find is HC2 Holdings:
1-800-667-0388
Help@HC2Broadcasting.com

If I was at your location, I would want to see if I could find the signal using a $25 USB dongle and SDR# (SDRsharp) software.

It's owned by HC2 Holdings. I checked their web site which has a list of stations and KQMK isn't there. There is a contact email for help, so I emailed today. We'll see what turns up.

I was up on the tower today and replaced the bad cable to my second antenna pointing to Lincoln. Some Lincoln stations came in and the Omaha were not adversely affected. I didn't bother scanning with only the one antenna for KQMK. I figure since it's weak in Bellevue at 3 miles, 25 miles is hopeless. (TBH, still a bit nervous on top of a 50 foot tower, so I fixed what was necessary and came down.)
