Is the Automatic Antenna Tuners in the pro2 of similar design in the old 756??

If so, I have found the spec says it will tune SWR's of 3 to 1. In actual
practice it has handled SWR's in excess of 7 to 1 on many (but not all)
occasions. It has always handled SWR's of 5 to 1 except on one occasion on 10
meters. Moving a few 10's of KHz and it would tune it.

Like Specification on most items, they are limits that the unit is guarenteed
to met without damaging itself. Operation outside those specifications is at
your own risk.

I also had an ICOM 737a and had similar performance with it's automatic antenna
tuner. (Same antennas)
