I have been experiencing interference that looks like wide-band data bursts from 120MHz - 150MHz+ which is destroying my NOAA APT captures.
Here is a YouTube video of it happening:
What its not:
- My phone or router (tested LTE/2.4ghz/5ghz/Bluetooth)
- My PC directly (only happens on outdoor antenna, tried different ports)
- Likely anything in my house (don't run much, tested appliances and other electronics, and could not find any correlation between anything and the interference)
What I've tried:
- MW High-pass
- FM Filter
- Ferrite on each end of every cable used
- Air Choke coil (this has the most effect, without the coil, the energy bursts are stronger, but shortening or lengthening the coil does not appear to help)
Geo Info:
- Using an AirSpy R2, although interference can also be observed on RTL dongle attached to same antenna
- A supermarket is within 1000 feet
- An iHeartRadio tower broadcasting 1230 KHz and 93.5 MHz at 1 kW is within 1 mile
- An iHeartRadio tower broadcasting 98.5 MHz at 1 kW is within 5 miles
- LTE signal is strong with this antenna.
- Antenna is Custom Turnstile made of Coathangers
- Is intermittent, but damn coincidental with satellite passes (happens other times too)
- This is what it does to APT captures
Any ideas would be appreciated, thanks in advance.
