I agree this is not a Mikrotik thing, but rather a problem with ethernet in general. Seems the HAMS don't like Ethernet either. http://www.hamuniverse.com/linksys.html

This was not Mikrotik anything. I think it is several RF sources mixing in the switch and retransmitting a harmonic. It depends on what the combination of transmit Freqs at the site is. Shielded cable, ferrite beads and grounding did not help. Only physical separation stopped the problem.
