setting (0 or 1), there may be an unacceptably high number of
noises. Very low squelch settings also seem to increase the
number of reflections.
Because of the LD-350’s increased sensitivity, you will be able
to detect substantially more strokes from storms when using
the lower squelch values. However you will also detect more
electrical noises.
Whereas a squelch setting of zero may be appropriate for the
LD-250 or the StormTracker, the same sensitivity for the LD-
350 will be achieved with a squelch setting of about 5.
By setting the squelch to non-zero values, you are instructing
the hardware to ignore weaker strokes. This can be an
advantage in certain situations, such as when you are trying to
adjust the range scaling.
Unusually high antenna placements (greater than 10m or 30
ft.) have the unfortunate ability to receive an unusually high
amount of weaker strokes. This can cause the ranging
algorithms in Lightning/2000 to produce incorrect results.
When used in conjunction with the Range Scaling Dialog, the
squelch setting can be used to correct ranging problems.
Users with very high antennas (> 100 ft. or 30m) have set the
squelch to a higher level and then set the range scaling factors
to higher values than normal in order to correct the ranging.
Antenna rotation (degrees)
Correct for an antenna that is pointed away from due north.
A positive value will cause new strokes to be drawn counter-
clockwise from the location they would have been drawn in.
A negative value will cause new strokes to be drawn clockwise
from the location they would have been drawn in.
Board address (hex)
This is the hardware address where Lightning/2000 expects to
find the lightning detector card. The default value is 360h.
