If you disconnect the ground connection to the average PC, the chassis
will sit at half supply potential above ground.
That's potentially 120V between your computer and radio, more than
enough to damage the radio.

Most new amateur radio operators start with the no-code Technician
Class operator license. Some newcomers, however, begin at the General
Class. A few even begin at the Amateur Extra Class.
That they start with the Extra class license doesn't necessarily mean that they

No. You can't have half a turn on a toroid. It's only an extrsa turn if
it passes through the middle. You can do as you please with the ends.
If a toroid has been wound backwards, it is best to strip

It must also be remembered that most amateurs are not on this reflector.
Most of those here will be keen constructors. I tend to buy the rig,
pull it apart to see how it works (or doesn't work, after I've finished

Hi Ken.
My pooter doesn't have any serial ports so I use USB/serial adaptors.
