I just was reading about this radio.
http://www.galaxyradios.com/cb/959.html
says it has an "Automatic SWR Circuit (no complicated calibration
procedure)" Does that mean the circuit sets the SWR automatically?


No. It means that it will read the SWR ratio without you having to
manually calibrate the meter. It does not correct the problem if there
is one.

If you move the radio from location to location just check the
reading. If it's 2:1 or lower don't worry about it.
