Switching on AFC
• Tune the receiver so that the frequency of the signal is
within the bandwidth of the filter
• The square beside "AFC" stops flashing when the AFC
locks onto a frequency and the receiver is tuned to the
signal frequency
• The square beside "AFC" flashes if the AFC has not
locked because the signal frequency is outside the
capture range
• The AFC will not lock if:
– the signal frequency is fluctuating rapidly or there are
large jumps in the signal frequency (select a larger
bandwidth)
– the signal level is too small
