SET MODE 10 D Scope audio output Sets the audio output function while scope operation. SCOPE-AF-OUTPUT OFF -ON SCOPE-AF-OUTPUT OFF >ON No audio output while sweep operation AF output while sweep operation The scope audio output is used for finding out the signals while scope function are modulated, unmodulated or beet signal etc. D Offset frequency Sets the duplex of-fs-e-t-f-re-q-u-e-n-c-y-fo-r-e-a-ch frequency band independently within 0 to 159.99999 MHz range. During duplex operation (-DUP or +DUP), the monitoring frequency (while [SQL] is pushed) shifts the set frequency. OFFSET-FREQ ----0.000.00 OFFSET-FREQ 159.999.99 The default value may differ according to the selected frequency band (before accessing set mode) and receiver version. The selected tuning step in VFO mode is used for the offset frequency setting. D Duplex direction Sets the duplex direction. The displaying frequency shifts the programmed offset frequency (at left below) when monitor function is in use (while pushing [SQL]). • OFF : Simplex operation. (default) • -DUP : The displaying frequency shifts down dur- ing monitor. • +DUP : The displaying frequency shifts up during monitor. DUPLEX OFF --DUP -+DUP DUPLEX OFF --DUP >+DUP Simplex operation Positive duplex operation 10 56
