② 

Frequency Step size:

 You have to manually choose between 0.1, 0.5, 1, 2, 5, 6.25, 9, 10, 

12.5, 20, 25, 30, 50, and 100kHz. 

③ 

RF Preamplifier:

 Select either 

auto

ON

 or no selection for disabling the preamplifier. 

④ 

RF Attenuator:

 Select either 

auto

0dB

10

dB, or 

20dB

 of attenuation. 

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 Step section. For finer tuning, use lower STEP values. 

⑧ 

Volume  Control

:  Represents  the  AF  audio  output  through  the  external  speaker  & 

headphones sockets. The SR2200 has no internal speaker! 

Volume scale is from 000 to 255. Beware of excessive volume level when using headphones. 

⑨ 

Functions not supported. 

 

TERMINAL-THE COMMAND WINDOW 

 

Access  the  Terminal  window  through 

the VIEW menu. 

 

 

 

 

This window allows you to monitor the 

data flow from SR2200 to the PC, and 

to  check  upon  the  SR2200  data 

response when a Command Instruction 

has been entered.
