What WiFi router are you using Jim? Thanks, Chuck W4NBO I'm using only one Ethernet cable, between cable modem and WiFi router. WiFi does everything else. It's a great solution to eliminate another s

Lots of good tools available nowadays to track this stuff. Agree Dave. Lots of noise out there. Of the last 2 power line issues I successfully found, the single thing that helped me the most to find

Interesting you would bring this up. My current 120hz target peaks at roughly 19.5mhz. Falling off below roughly 10mhz to where its almost insignificant and goes up to about the 2 meter band where it

Sounds like my neighborhood. In locating my last source (a horrible 20-30 over S9 on 75m), the most significant break through for me was matching the noise pattern to what I was hearing in my hf rece

So let me get this straight. If hams make false complaints then the utility is ok to blow us off. But if they make false statements or findings, then its ok. Got it. I think 120hz noise is a much lar
