(5) Signal Strength Meter: It is for relative signal strength comparison and calibration may not be
totally reliable.
(6) Squelch Control: There are 2 types supported, NOISE squelch and (signal) LEVEL squelch.
Move the slide to the right (for values from 0 to 255) until the unwanted noise disappears.
(7) Manual Frequency Tuning: Using the left arrow (for tuning down) or the right arrow (for
tuning up) you can decrease or increase the frequency by the value defined in the (2) Frequency

(8) Volume Control: Represents the AF audio output through the external speaker &
headphones sockets. The SR2200 has no internal speaker!

(9) Functions not yet supported.
TERMINAL-THE COMMAND WINDOW
Although this function is more for
testing purposes, and still under
development, you may access the
Terminal window through the VIEW
menu.
This window allows you to monitor
the data flowing from the SR2200 to
the PC, and to check upon the
SR2200 data response when a
Command
Instruction
has
been
entered.
So
far,
only
READ
commands are supported, WRITE
commands are not.
If you would like to use READ AND WRITE commands easily and extensively, we would advice
the WINDOWS TERMINAL SOFTWARE, included in all Windows versions.
