In the AUTO mode operation the MAC-200 remembers not only
the frequency, but the antenna. The tuner will save the selected
antenna along with the tuner settings when a successful match is
found. Both the tuner settings and the antenna settings will be
recalled the next time the MAC-200 is operated at that frequency.
Antenna settings are kept in a special set of bins. Only one antenna
may be stored in each bin. The upper frequency limit on each bin is
given in the table below:
When changing the selected antenna in AUTO mode, the LED
above the AUTO switch will blink for 10 seconds after a new
antenna is selected. Transmitting while the LED is blinking will
cause the MAC-200 to store the antenna selection in the
appropriate bin. If no transmission occurs while the LED is
blinking, the MAC-200 will go back to its stored antenna.
