If you know the attached antenna will always
be good, you can disable antenna detection.
This will prevent the radio from down-
powering and the radio will always output the
selected power. (Assuming the radio is cool
enough.)
p. The Antenna VSWR displays the Standing
Wave Ratio. Any value less than 4:1 is
reasonable. The lower the number, the
better:
Values higher than 8:1 result in a ‘no antenna
connected message.’
q. One last right click and you are back to the
Device Status:
r. Clicking the ‘down-arrow’ will display the
owner name:
s. Down arrow to the FCC ID which is
transmitted in Morse Code every 15 minutes:
t. The modulation type is GSMK:
u. In almost all cases for all current FCC licenses
in the United States, the channel bandwidth
must be 12.5 KHz or less to meet current FCC
requirements:
v. This screen indicates if the transmitter is
enabled and what the output power is:
On hot days, it is possible that the radio
power setting is higher than the enabled
value. Power will also be reduced if Antenna
Detect is enabled and a fault is detected.
w. This is the internal temperature of the
receiver:
Power management becomes active when
this temperature is higher than 85 deg C.
x. 30 seconds after you switch to the DutyCycle
screen, the transmit duty cycle of the receiver
is shown:
