there are no signals present.
Make sure to first select a channel not in use before setting
the squelch in your MHS050 VHF Marine radio.

Operation
Think of the squelch control as a gate. If you
increase the squelch level to maximum it
raises the ‘Squelch gate’ so only the strongest
signals get through.
If you decrease the squelch level to minimum
it lowers the ‘Squelch Gate’ to the extent that
weak signals can get through.
If unwanted weak and noisy signals are getting
through increase the squelch level (‘Squelch
Gate’) to a medium level. Now only medium
and strong signals get through.
