Dears,
My station stopped receiving discharges. It is "Station 2927, BLUE, FW 9.4, PCB 19.5/H1/E1"
'Fault' LED is continuously on, I believe because of 'Fault' mode.. because of overload/interference?
Everything began on a day, when there were big electrostatic discharges in air.
Radar's antennas collected static, and presumably, burnt something on PCB.
Radar was connected to Internet via unmanaged switch over ethernet cable, which has been burnt that night - had to be replaced.
Static was so powerful, that I heard 'clicks' in the middle of the night from another room. I walked into the room where radar was located and saw sparks near antenna connector. I had to use insulated pliers to unscrew F-connector.
Good news: built-in GPS module works, network adapter works.
With disconnected antennas, from debug log:

I did open receiver and visually inspected with a loupe, there is no visible damage.
I belive, that static damaged something, but my knowledge is limited to design/construction.
Anybody has similar issues?
Where to troubleshoot?
Any help is appreciated.

| Raw schematic files? |

Hello! Other threads relating to this haven't been active for several months, so I figured I would start a new one. Was looking into setting up a detector to contribute data and get access to raw data, but it seems those are impossible to purchase at the moment, so instead I am looking into manufacturing my own.
I have located screenshots of schematics and board files at this link (https://www.blitzortung.org/Compendium/H.../PCB_20_7/ which is linked publicly in the documentation), but I was unable to find any raw schematic files (to open with EDA software to generate gerbers). Are these available anywhere so I can generate files and order parts to manufacture a board myself?
