A typical spectrum analyzer display is shown in Figure 8 . The display
creates a received signal strength indication (RSSI) vs. frequency plot
for the frequency and surrounding signals. By analyzing the display,
you can determine the presence of other signals near the transceiver's
operating frequency. This information can be helpful in trouble-
shooting interference problems.
SQUELCH [AUTO, BYPASSED]
Squelch Operation
Set or display analog squelch bypass.
SREV
Software/Firmware Revision Level
This command displays the software revision level of the transceiver
firmware.
STAT

This command displays the current alarm status of the transceiver.
If no alarms exist, the message

appears.
If an alarm does exist, a two-digit code (
00

) is displayed and the
alarm is identified as “Major” or “Minor.” A brief description of the
alarm code is also given.

TOT [1-255, ON, OFF]
TX Timeout-Timer
This command sets or displays the transmitter Time-out Timer value
(1-255 seconds), as well as the timer status (

on, and the radio remains keyed for a longer duration than the
TOT
value, the transmitter is automatically unkeyed.
