I finally figured it out, well sort of.... from an earlier post:
"A few years ago all of the house (kitchen and office) phones were dead. The 50 year old main line from the box must of had an open. The phone line at the alarm was fine and so was the return line that went to the garage and the rest of the house. I disconnected the house end and ran a line from the alarm, down into the basement to junction box where the kitchen and office lines connect. Everything was fine. "

This past weekend I disconnected the open line from the Verizon box and the problem went away.

At the time of the open, I did not have Verizon service but was utilizing that line until I reconfigured. I never disconnected the open line and when I switched to Verizon I was getting some sort of signal that must have been causing the problem with mj. Further more, the open line was laying on roof flashing and when it rained it must of grounded the line causing the weather related problem (without mj there was hum and with mj no hum).


Thanks for all of your help and teaching me a thing or 2.

Glad you finally found the problem!
