Maybe. lightningmaps.org might be persuaded to give a suitable regional based activity plot.
Glad you've got your system sorted out. If memory serves something around 45 kHz occurs when the controller and PSU don't get on with each other. If you can see it with LP filters enabled and set to < 20 kHz it isn't getting through them, they really are very steep and deep. I see no sign of MSF on 60 kHz on any channel with a LP filter set to <20 kHz, if fact 54 kHz is enough to have pretty much the same effect. And that'll be on a channel with the best part of 100 mV of p-p 60 kHz present, same channel has 200 mV p-p of 19.6/22.1, unfiltered.
I know have Ch1 loop with it's null aimed to get minimum Anthorn/Skelton, which means it's lobes are almost exactly N/S. Gain is normally 2560 with 50 - 60 mV "noise". Ch2 loop looking NW/SE as far as it can go W/E without Anthorn/Skelton being so F***ing loud they constantly trigger the system, that means about 200 mV p-p unfiltered. I filter this channel at 17 kHz which brings that down to the 50 - 50 mV range with a gain of 4000. This is the only channel I have a filter in.
The system seems to be working very well. Yesterday there were many in the western end of Iran and the area where Turkmenistan, Uzbekistan and Kazakhstan all meet the far side of the Caspian Sea. That's 2,700+ miles (4300+ km). See attached:

I'm not sure I believe the few participated and other strikes that show up south of the equator off the coast of Congo/Angola! They are 4,200 miles (6,700 km) away... Is there a way to verify them?
