In discussing various coax choices and installing different radio sets, it
came to me to suggest to our lesser radio-concious fellows to make a
suggestion which I hope will avoid some bad results otherwise.
There are grounds (earths) and other grounds.... When an electronic device
is planned for installation, there may be two grounds involved - ne'er the
two should meet. there will be a DC ground whence cometh the juice to power
the beast. There is also a RADIO ground which is used to connect two parts
of the radio. Sometimes these two are confused, or even badly described in
the text. ALWAYS ensure you know exactly which is which; otherwise it's
likely that interference will show up later.
Ferg.
