Only post I see about this from Cutty was a suggestion for troubleshooting.
Even in that post he said he did not believe the shielded LAN cable was causing the noise.
I use as shielded LAN cable, I have no issues.
My thoughts have been to use shielded to contain the rf signal in the Ethernet cable and not radiate to the antennas.

In case you do not have the case this plan of the back pannel may help.
Network: Ethernet cable to the network.
H-Field: RJ45 cable to the H-Field board.
Both should be shielded, for the H-Field shield is a must have.
Thank you for sending the diagram. Egon rectified our RJ45 issue for us. We are a "running station" now. However, as far as I can tell, we are not contributing, so I am searching for threads on the forum about how to figure out what the problems are and how to troubleshoot them.

Looking at your last signal sent to lightningmaps.org, you seem to be getting some heavy interference. Check for cfl lightbulbs, some flat screen tv’s, power supplies, etc. if you have a portable AM radio, you can walk around the house with it on and pinpoint a lot of noise sources. I had a flat screen LCD tv that would render the system unusable throughout the whole house! I replaced it with with an LED tv and all was well.
Good luck!!
