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.
When operating in MANUAL mode, the MAC-200 ignores the
antenna setting, but the antenna tuner continues to function. Tuner
settings will be stored and recalled from memory without changing
the antenna selection setting. This may cause retuning when going
back to the AUTO mode since the antenna and the tuning settings
may no longer match.
Tuner settings are stored in predefined ‘bins’ across the range of
the tuner. The width of each bin varies with frequency, but
averages approximately 170 kHz per bin, with more bins at lower
frequencies and fewer, wider bins at higher frequencies. Retuning
may occur when working at opposite ends of a bin if the change in
