What type of antenna, how close to the shack and have you installed any common mode chokes?
- Glenn W9IQ
I have a fan vertical (three wires for 10/15/20) with ground radials, and they are probably 15 feet from my desk, separated by an outside wall with a lot of windows. Coax enters the house, goes through a coax switch and then my radio.
I ordered a bunch of Fair-Rite snap-on chokes of various sizes and will receive them soon. Wrt coax, I was going to start with one or two near the antenna, and some in the shack near the antenna switch and/or the radio.
I expected to use some chokes on the mouse and keyboard cords, but then thought maybe I could just eliminate those cords with Bluetooth.
There are also power and USB cables to worry about.
I have been reading a lot, including the papers by W1HIS and W9JI.
I saw an article on a home-brew common mode current detector, and thought that would be really useful. But such things don't seem to be very common in my experience - maybe they don't work that well in practice.
As a new ham, I am just getting started on this issue.
