SDS100/SDS200: SDS200 interference caused by ethernet LAN wire?

[MikeyBeeUSA]

Hey all. I recently got my SDS200 and I have ti all linked up to Proscan via LAN. My question is as follows: Has anyone else experienced receiving any interference on a frequency after plugging in a LAN, on a frequency where they did not experience said interference prior to connecting the LAN?

I'm waiting on an antenna to arrive, so right now I'm just using the back of unit antenna. But prior to inserting the LAN (and when I take it out) I had no signs of interference on the frequency in question. Post LAN, the transmission has a very buzzy electronic sound over it.

It's actually a couple of different frequencies all on the same county system. Analog freqs. between 154.755 - 156.165.

Thanks in advance for any context and/or advice on how to correct this!

Yes, it's coming from whatever the other end of the cable is plugged into (switch/router). Shielded cable resolved it in my case.

You could also try these... Attach one on the ethernet cable close to the switch/router...

I get random birdies and static in vhf around 155 MHz when using the vonets I don’t get that when using cat 6

All electronic equipment can generate RF interference and it's usually in the VHF-LO and VHF-HI frequency ranges. I have a lot of those but have actually never heard any interference in the UHF range. I have a Raspberry Pi 5 mini computer board in a plastic box that rest on top of some coax cables and it's crazy how much RF interference it generates over the whole VHF band.

USB is very good at generating emissions across 70 cm.
