Hello all,
I am in the process of putting up a 2M repeater on what I would consider a
pretty vacant site. There is only one other machine (70cm Repeater) currently
out there. My concern is with an AC (60Hz) buzz that comes across on the VHF
band. It doesn't have a signal to it that will

Wade,
This sounds like a defective insulator or cable clamp sparking on a power
pole. Such interference can carry for many miles. Try using a portable
radio with a handheld Yagi antenna
Distribution voltages begin at 2,400 and go to 34,500 volts. Transmission
voltages begin at ... depends upon the utility. Could be 46,000, 69,000 or
115,000.
Anyway... it's not the voltage. It's simply there is a device issue somewhere
on a power line.
Could be a bad connector. A

Remote hilltop sites are very often fed with a lateral power line that

the hilltop site is on that lateral, and with the site owner's permission

I had a similar problem at my house and it was tearing up my packet
