Triple Frequency Conversion - virtually eliminates any
interference from IF
(intermediate frequency) images,
so you hear only the selected
frequency.
Limit or Direct Frequency Search - lets you search within a
specific range of frequencies or
all frequencies, starting
directly from a specified
frequency.
Service Bank Search - lets you search the frequencies
allocated to the air traffic,
fire, marine, or weather
services, so you can listen to
the services you prefer, even if
you do not know the frequencies.
Ten Channel-Storage Banks - let you store 20 channels in
each of 10 banks to group
frequencies so you can easily
identify calls.
Two-Second Scan Delay - lets you delay scanning for
2 seconds before moving to
another channel, so you can hear
more replies.
Memory Backup - keeps the channel frequencies
