Thanks! This list is like graduate school

I just changed out an ATOM mikrotik to a CCR, and found that it is
Incrementing FCS Errors exactly every 30 seconds on the Ethernet line
from a Trango LYNX. The lynx is powered via DC, so the Data line is
clean of POE. I am using a GIGE-APC Unit on the Ethernet line.

This is not a High RF Site. Ham Operator and a Helicopter Relay for a

meter? From the APC Ground line to the building ground?

I don't remember is the GIGE-APC high voltage? If this is a low voltage
unit, you may be seeing some sort of ground bounce and/or RF triggering the
surge supressor.

Start with DC before and after it. Keep it attached for a bit...then try
AC as well. Make sure all cuts are clean and uniform. No need at add more
antennas to the mix.

Seen this happen before. Has to be a potential between one of the ethernet
lines and ground. Sometimes it is because someone used a LV version instead of
a HV version.

Ground bounce is where the ground potential moves. Usually it's a phrase
used in high speed circuit design where the switching currents cause enough
current to flow that the negative reference for a given part to be higher
or lower than the rest of the circuit.
A fair number of people seem to
