✔ What is squelch?
A squelch circuit allows you to mute undesired noise while re-
ceiving no signal and emit audio while receiving signals.
This provides quiet standby. The [MONI] key cancels the
squelch setting. This is useful to listen to weak signals that
do not open the squelch.
✔ Talk Range
The IC-F22SR is designed to maximize performance and im-
prove transmission range in the field. However, the single
most important factor in transmit range (talk power) is your
surrounding environment. These radios are “line of sight” ra-
dios and as such, transmission range is influenced by the de-
gree to which you can “see” the other communicating party.
Large concrete structures and heavy foliage or transmission
from inside a building or vehicle will reduce your talk power.
• Optimal range: wide, open areas free of obstructions.
• Medium range: large buildings or trees blocking your line of
sight.
• Minimum range: mountainous areas or areas of heavy fo-
liage.
