RF signal for the unit to not engage the squelch feature.
NOTE: For squelch settings 1-3, the squelch function is slow which allows for maximum
transmission range. For squelch settings 4-20 the squelch function is fast to ensure little
radio noise is heard during the squelch function.
NOTE: Keep in mind, low squelch may allow multipath and squelch chattering at long distances.
