I have been experimenting with the lightning strikes and the gain factor of antenna and preamp.
When the gain is set a little to high with consideration to the antenna being too high in receive
performance we have desensitizing effect. An auto gain feature would work well . As I discovered
the newest TOA board that has come out version 10 I saw spoke of an auto gain feature. This
I guess addresses the issue I have found.
I have designed my antenna as a 2-foot pvc loop antenna with 25 turns, 22gauge stranded
wire and gain set at preamp of 43x Gain. Channel A,B jumper set on pin 2.
The preamp board is PCB 5 version 7, Data board PCB 6 version 8.
Are there any newer preamp board versions available?? Please let me know.
I will be looking into an auto gain method. Or finding a setting that fits
both distance and local strikes which will give best effciencies at 5000km
and moderate level efficiencies.
The best we can do is use a gain that will fit most instances of nearby high activity
storms as well as distance ones. Or find a way to build an auto gain preamp.
