Receive Mode; Transmit Mode - Spectrum DSP M2 User Manual

Spectrum DSP M2 User Manual V1.1
Operational modes and functions:

Receive mode:

After powering up, the Spectrum DSP will revert to receive mode on the last frequency, in the
mode and using the audio bandpass filter that was in use when it was last powered down
using the POWER button.
To adjust the volume click the DSP mode button and make short swipes up and down on the
left-side of the screen. The AFG box number will change as this is done, adjusting the
volume level.

Transmit mode:

In transmit mode most of the controls are locked, this being done to prevent the change of
frequency, filter type and mode during mid-transmission.
TUNE mode: Virtual dial
Tune mode may be entered by pressing the button located below the TUNE/O button on the
lower screen.
Figure 6: The virtual dial mode provides accurate frequency control.
Draw a circle on the screen as if you were spinning a dial to tune. If you want to tune faster
you can also make a long-press on [VFO A] which will then turn red to indicate that fast tuning
mode is active. Both modes provide accurate frequency control.
Pressing the TUNE button again will exit to the scope tuning mode. Clicking anywhere on the
scope will change frequency if the Spectrum is in Master or BiSync modes and the CAT cable
is connected to the transceiver.
