Incremental Tuning Pad

This unique tuning tool is located above the Tuning Knob. If the mouse is

positioned above one of the coloured squares, the square lights up and the

associated tuning increment value appears:

Clicking on the square with the left mouse button results in increasing the

frequency, clicking with the right mouse button will decrease the frequency.

There are several convenient tuning increments to choose from: 1 Hz, 10 Hz,

100 Hz, 1 kHz, 5 kHz, 6.25 kHz, 8.33 kHz, 9 kHz, 10 kHz, 12.5 kHz and 25

kHz.

Tune To Peak

The Tune to Peak function can be invoked by pressing the TTP button. The

receiver will tune to the signal peak (provided the peak falls inside the selected

IF bandwidth – the highlighted area of the real-time frequency spectrum).

Depending on the location of the peak and type of signal, it may take several

seconds for the receiver to tune in accurately, by a successive approximation

process.

In the FM mode, the Tune to Peak function will work correctly, i.e. tune to the

centre of the signal, even though the sidebands may be higher than the carrier

frequency.

In LSB and USB modes, the success of this facility will depend on the type of

modulation signal. It may be useful for certain types of data modulation (fax),

but is not usually recommended for voice modulation.
