Had an odd problem with our SX5 blowing certain FETS and PA fuses. Turned out to be one of the coax connectors from the divider to the PA stages had become loose. Found it when I re-seated all the connectors to the PA modules. Never worked in a gates one but maybe something similar. Mark Brockmeyer.
Started working with KYFR 4 tower directional. Currently there is no tower light monitoring system. Manually done nightly. The flasher and photocell are on each tower for 2 OB and 1 Beacon. The lighting choke only brings across a single phase circuit with combined current for both beacon and side ma...
What the FAA and FCC process for removing side marker requirements? Wondering if we can file it ourselves without using a consultant. It's a 3 tower array. We currently are only required to light the center tower since it 480 feet.

We sent pictures to the original painter. Who has agreed to give the red bands another coat and touch up the white bands where needed. Hopefully this will last more than 5 years. Then we will plan doing the whole tower. Painter was shocked at how much the red bands have faded away in less than 5 yea...
My question is. Since this first coat is disappearing so quickly. Not fading or chipping its disappearing for some reason. Do we need to do 2 coats or will one more coat be enough?
Need some feedback on painting a 1000 ft fm tower. 1000 ft tower put up in 2009 with strobes and not painted. In 2013 we moved to LED lights and painted the tower. Saved us a bundle in strobe repairs. We only put one coat of paint on the tower and no primer. As you have guessed the red bands are qui...

Tossing an idea out there. Our AM 3 tower uses about 17 acres. I have wondering if some of the land could be used for a solar panel farm. There is a lot of southern exposure and a couple of miles from a midamerican energy substation. Several arces are outside the guy radius. The solar panel farms I ...
Got them up and running again. Full power day and night. A bit hit and miss with the RF switch control wiring with out a schematic. The replacement RF switches had different control wiring than the orginals.
Wondering if anyone knows anything about KYFR site, south of coin, Iowa. Its a four tower AM. Doing some work for them on the side to resolve problems with both RF and directional control wiring. I bit like exploratory surgery right now, blind folded. Need to find diagrams on the directional system ...
We have had other calls at the same time with no problem. The two factors seems to be weather eye and the time. We are going to try to use a flipping extensions to see if it is extension. We have tried changing who originates the call with no difference. I wish I could just them to change the times ...
Not sure this the right forum. However I will post what is happening and see if anyone has an idea what is happening. At 6:45am and 7:45am exactly we are getting an audio drop on our calls with Weather eye. It only lasts at most 3 seconds and sounds like call waiting. We don't lose the call just the...
For that distance, I would think a 900 mhz data link on a couple of yagis would do the trick, even through some trees. Ubiquiti, or Mikrotik, and the like. I'm using Mikrotik radios diplexed into one of my STL paths, and it works great across the Sacramento metro out to south of rancho cordova. dav...
