[Elecraft] IMac pro RFI

[Ramon Tristani]

I have an iMac and a Macbook, both operating within 6 feet of the K3 which drives a 5BTV vertical in my backyard. I run the full 100 watts without any RFI to my Macs. Guess you may have a defective iMac that should be returned for exchange or refund. My iMac is connected to the same AC circuit as the K3 with no special or separate ground for the K3.

73s,
Ramon, KP4GE
