Setting Dual or TripleWatch (Tri Watch)
[For Marine and FRS Band Only]
There are two specialty
channels: 16, and 9. Channel
16 is the primary distress/
Coast Guard/Hailing channel
while Channel 9 is typically the
backup hailing/calling channel
for areas where there is higher
level of marine trafc. Depending on your location, you can
choose to monitor both distress Channel 16, the extra hailing
Channel 9 as well as the radio channel you are otherwise
using (TripleWatch), or you can choose to only monitor
Channel 16 and your regular channel (DualWatch) which lets
the radio check each channel more frequently.
