MAN mode or AUTO mode?
Unless you intend to operate the KAT500 in a remote configuration where it may be a long distance
from where you will Control it, Elecraft recommends using MAN (Manual) mode.
AUTO mode has an additional feature where the tuner will monitor SWR while you are transmitting.
If, for some reason, the SWR rises above about 1.8:1 threshold (the default), AUTO mode will cause
the KAT500 to enter Full Cycle Tune mode without you starting it. When used remotely, this is a very
effective way of accommodating wide-ranging SWR due to weather or other conditions. Successful
Full Cycle Tunes in AUTO mode will be memorized just as they are in MAN mode.
AUTO mode thresholds can be set by the operator, too. Use the KAT500 Utility to enter the
Configuration dialog and select Thresholds. There you can specify, by each ANT port, what level of
upper and lower thresholds you want the AUTO mode feature to monitor.
MAN mode will store successful Full Cycle Tunes just as AUTO mode will and the KAT500 will monitor
SWR while you are transmitting. However, the KAT500 will not act if the SWR rises of falls. You can
monitor it for yourself directly from the front of the KAT500 or from the KAT500 Utility.
