Hey all...Just bought a 101B right here off of Eham. Tech right now but will be General class in short order. Before I ask my question, I did spend quite a bit of time searching to see if it was answered before. Anyhow, I know that the stock AC line cord is 2 conductor. After looking over some diagrams and other research, it appears as though there is chassis ground at that connector. What I can't seem to get consensus on is which pin is chassis ground. Now, if I were to install a brand new, heavy gauge cord like 12/3 would this serve as grounding the radio?
I don't think there's any point in replacing the cord. That radio runs from a transformer that provides full isolation. There should be no safety issues with an isolation transformer.
If you use a balanced antenna like a half wave center fed dipole, you should not need any ground to get the antenna to perform normally.
There are three kinds of grounds.
1. Safety, and that's handled by the isolation transformer.
2. RF ground and you won't necessarily need one with a balanced antenna. If you don't have a balanced antenna, the RF ground is generally placed at the feed point.
3. Lightning. And that one needs to be outside using a single point ground entrance panel.
