I think the tuning step is 1Hz all the time. All the FINE control
does is change the tuning rate of the tuning knob to the display.
The display shows 10Hz resolution whatever you do - unless there is
somthing I have missed.
I made a simple test. Using the Up-Down pushbuttons on the
mike, the step for each pression is 10 Hz or 1 Hz depending
on the 'Fine' setting. The display has the resolution fixed at 10 Hz,
but the actual zero-beat carrier received can be adjusted in steps
of 10 or 1 Hz. Not bad for a non-professional RX.
