UNIDEN MHS050

Handheld VHF Marine Transceiver

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.
