I have this very old, but in very good condition, SWR/Field Strength
meter with out the instruction sheet that I would like to know
something about. It is a Thorotest SWFS-2, measuring 2x2x5, with the
connectors on each end and the meter, adjustment switch ( FWD, REF )
and control knob on a 2 inch side. I imagine this was used for CB
work, but could it tell anything about marine radio setup, without
damaging the radio?
Thanks,
Helmer
