RF Key Test
Using the RF Key Test action, the active radio can be manually keyed (transmitter enabled) or
de-keyed (transmitter disabled). This may be useful when diagnosing signal-strength on a remote
receiver.

Spectrum Analyzer
A unique feature of the transceiver is the ability to view the RF spectrum above and below the
operating frequency using its built-in Spectrum Graph. Often, this can assist in diagnosing the
cause of interference, or to view other signals near your operating frequency. To use the Spec-
trum Graph, you must first specify a center frequency and a scan width. The center frequency is
the frequency that you wish the spectrum display to be centered on. The span frequency defines
the width of the overall spectrum to be examined.
Once the correct values have been entered, switch it on by sliding the on/off switch. The graph
will automatically refresh itself every 5 seconds. To stop scanning, turn the on/off switch off.
