• Multipath
Multipath interference is a form of RF interference that occurs when radio signals have more than one path
between the receiver and the transmitter causing the two RF signals to add out of phase. This could occur in areas

and out of squelch when the receiver is moved. Portable applications are much more susceptible to multipath
than those that are stationary. Multipath distortion is often worse as the distance between transmitter and receiver

Eliminating Multipath
As mentioned on page 5, multipath can occur with portable RF systems. The audio quality of the
transmission can decrease with the occurrence of multipath. Here are a few potential improvements that

Squelch
Squelching the receiver will mute the audio output when the signal from the transmitter is turned off or
the signal is too weak to be received. Without squelch you would hear radio noise in your earphone with
no RF signal present. “Tightening” the squelch will turn the receiver off if it is chattering because of
PXOWLSDWKUHIHUWRSDJHIRUSURJUDPPLQJVTXHOFK.HHSLQPLQG´WLJKWHQLQJµVTXHOFKZLOOOLPLWWKH
range between transmitter and Receiver.
Transmitter power level
7KH5)SRZHUOHYHOFDQEHDGMXVWHGRQWKH/7UHIHUWRSDJHIRUSURJUDPPLQJ/7SRZHUOHYHOV
The lower the power setting, the less range the transmitter will broadcast. Decreasing the broadcast range
will force the receivers to remain closer to the transmitter. To maintain an RF signal, the higher power
settings will increase range between transmitter and receiver thus introducing a higher probability of
multipath.

Squelch
Much like a multipath situation, “tightening” the squelch on the receiver will mute the audio output when
the signal is too weak to be received. Tightening the squelch will help with force the receiver to squelch
