Main dial
t Rotate the main dial to tune to the desired signal and decode it correctly.
· Also use the tuning indicator of the TNC or software. · During SSB data mode, the 1/4 tuning function can be used for critical tuning.
Appears
y Operate the PC (software) or TNC to transmit.
· When operating in SSB data mode, adjust the TNC output level so that the ALC meter reading doesn't go outside the ALC zone.
NOTE: When SSB data mode is selected, the audio input from the [ACC1 (pin 6)] is used for transmission instead of [MIC]'s. 12-7, 12-8))
The fixed condition is used for SSB data transmission as follows: · [COMP] : OFF · Tx bandwidth : MID · Tx Tone (Bass) : 0 · Tx Tone (Trebles): 0

y Push [MARKER] F-3 to turn the marker for transmit frequency ON or OFF.
· " T " displays the marker at the transmit frequency. · "<<" or ">>" appears when the marker is out of range. · The spectrum scope shows the transmit signal while transmitting. Peak levels are displayed in the background of the current spectrum in a different color until the receive frequency changes. This can be deactivated and the waveform color can be set in scope set mode. 5-5)
· Scope spurious signal example Spurious signals may be received on the spectrum scope screen regardless of the transceiver's state (TX or RX). This does not indicate a transceiver malfunction.
u Push [HOLD] F-4 to freeze the current spectrum display.
· " HOLD " appears while the function is in use. · The peak hold function can be deactivated in scope set mode.
