Lightning strikes heard, but did not appear on map.

That's with the antenna on my porch about 10 feet away from my computer, router, TV not much further. 23 kv single phase power line 30 feet off the ground 30 feet away horizontally makes about 200 mv of AC on the loops to ground. Not much magnetic influence from any of that though. Did a digital 1 k high pass to remove what little was encoded by the ADC. Filter that is on amp board should do the same.

Antenna will be about 70 feet away from house when installed.
