These are the "North/South" channel and the "East/West"
channel. This had the effect of causing most legitimate
strokes to show up as reflections. This problem was easily
fixed in Lightning/2000 by reversing those channels. In other
words, the data from the North/South channel is interpreted
as having come from the East/West channel and vice versa.
However, it appears that when using the new v9 device driver,
the "channel reversal" problem has been corrected.
It is believed that no matter which device driver you are using
with the PCI card, the data is now interpreted correctly.
Therefore, you should never have to check this option.
However, if it seems that all strokes are reflections of the real
lightning activity, we cannot rule out that (inexplicably) the
data channels are "flipped". That is why this option was
added.
When checking for reflections, make sure that you are looking
ONLY at the Raw Lightning Data window and that the View
| Strokes option is selected. If you are in stroke mode, then
you will automatically be viewing strokes in the Raw Lightning
Data window. Otherwise, you will need to select the
advanced mode arrangement of windows and manually select
View | Strokes in the Settings dialog (choose Settings…
from the right-click menu).
Receiver squelch
This setting determines how sensitive the lightning detection
hardware is. Setting the squelch to 0 allows the hardware to
detect everything, when using the LD-250 or StormTracker
hardware.
The LD-350’s squelch setting operates slightly differently. A
setting of 7 approximates the zero setting used by the other
hardware types. You can set the squelch lower than 7 and
detect increasingly weaker strokes from storms, some of
which might be very distant. When using a very low squelch
