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.

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.

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; 5-30 is acceptable; 30+ indicates that the connections should be inspected for loose

connections and cable quality.

RANSMIT CURRENT (MA)

This measures the current draw of the transmitter in milliamps. Refer to Transceiver specs for typical

values.

VERAGE NOISE LEVEL

The average noise level indicates the level of background noise and interference at this transceiver and

at each of the Repeaters in the link. The number is an average of the noise levels measured at each

frequency in the transceiver’s frequency hop table. The individual measurement values at each frequency
