The minimum guaranteed working distance for Ronja is 1/15 of range at 4km visibility (nominal range). Therefore for nominal range 1.4km it's 93m. If you need to make Ronja run on N-times shorter link that 1/15 of maximum, change capacitor in 10M Receiver for a series combination of resistor and capacitor as seen in the schematic.

The maximum distance will be affected by this too, but much less than the minimum distance.
