Flex 6300 Ethernet port

Yes, I saw the other post…

I run two Flex6300 on two different locations. Both suffer from RFI in the ethernet port. Transmitting high power on 160m or 80m make the radios crash. Ethernet port stops working, comes back after 2 minutes.

My antennas are top notch with Rl over 20 dB.

But when you make 1 kW on a Vertical antenna 20 meters away you have more than 3V/m field strenght.

I have 38 ethernet devices in one of these two locations. ONLY the Flex6300 goes offline. My conclusion is that the ethernet transceiver used in there is ****…

How to fix this ? Very short wire to fiber converter ??? Buy a better radio ?

Lacking any schematics of the 6300, is there maybe somebody from Flex here who could give me the part number of the (bad) ethernet interface connector used so we can check the data sheets and see what can be improved ?

Maybe there are pin compatible better ones.

So many complaints on the internet about the RFI on the ethernet port of this radio….

And yes, I already tried 2 tons of ferrite :-)

Are you 100% sure the problem is in the radio? More often than not, the RF problem is in the network switch from RF getting on the LAN cable. And, sometimes on the DC power cable to the network switch.

The excellent RI numbers on your antennas say that the antenna is doing good work at emitting RF and it might be that RF that is impacting your network.

Try this test and do a link.local connection with one radio and see if the problem goes away. We want to remove as much of your network as possible to run this test and help isolate things.

If it does go away, then you need to look some other place for the loss of network communications.

Let us know how you make out.
