Show Radio Statistics
Radio Statistics in the Main Menu allows the user to view data transmission statistics gathered by the
transceiver during the most recent session. This is valuable when the user needs to know the signal
strength and noise levels of the link. Statistics are gathered during each data link and are reset when the
next link begins. See display below.
N
UMBER OF DISCONNECTS
Any time the link between the Master and the Slave is broken and the radios lose Carrier Detect, it is
recorded in the Number of Disconnects value. The value indicates the total number of disconnects that
have occurred from the time the transceiver is powered on until the radio is put into Setup mode. Under
ideal operating conditions, the number of disconnects should be 0. One or more disconnects may indicate
a weak link, the presence of severe interference problems or loss of power to any of the radios in the link.
A
NTENNA REFLECTED POWER
This is a measurement of the transmitted power that is reflected back into the transceiver from
mismatched antennas or cables, or loose connections between the transceiver and antenna. A reading
of 0-5 is good; 5-20 is acceptable. Once the reading reads 20 or higher, this could be an indication that
the antenna cable connections should be inspected for loose connections and cable quality. A reading of
30 or higher indicates a definite problem in the system. The most likely reason for a higher Reflected
Power reading is a cable issue between the radio and the antenna: loose connections, cable kinks,
breaks in cable shielding, moisture in the fittings or connections, etc. Less commonly, a high Reflected
Power reading can indicate a hardware problem with the radio itself, such as a dmage RF connector.
Lastly, a high Reflected Power reading may indicate a problem with the antenna itself, although antenna
problems are the least likely indicator.
