On kiwisdr.w1euj.com, I've got this blanket of pulsing noise over these frequencies. I'm looking for the most effective ways to figure out the source.
Location: KiwiSDR setup is located in the barn, which is 100 feet from the house (buried power line to it) and 200 feet from the house and horse barn on the adjacent properties. This is the only thing in the barn that is powered.
Kiwi: The Kiwi is in a metal trashcan, with the power, Ethernet and antenna cables running out the rim. The antenna input has a Mini-Circuits SMA LPF for 30 MHz.
Antenna: A large wire Vertical Delta loop in the trees behind the barn (about 30 feet away) with 50 foot apex, feedpoint at the bottom corner. 4:1 balun at the feedpoint, running to LMR style cable along the ground for 30 feet to the entry point on the barn. Runs through a grounded Polyphaser arrestor, then the wall, then inside for 5 feet to an Array Solutions reciever protector, then 1 foot of cable to the inside of the trashcan.
Power: A linear power supply (2-prong AC connection and inside a plastic box), with the DC lines then wrapped (10 turns) on a large ferrite ring before then running a very short distance into the trashcan.
Ethernet: This is unique. I an running a pair of Ubiquiti Bullet M5 radios to link the barn to the house. They are connected to small yagi antennas mounted on the corner of the barn closest to the house - about 20 feet away from the Kiwi and connected to it via the CAT6 cable. The Bullet in the barn is powered from a linear power supply. Both the power and Ethernet lines are wrapped through several ferrite rings.
