Wanted to get some input on the Fluvanna Louisa System. On 1/3/2022 around 0820 and for about 2 hours, the system experienced an "rx: illegal carrier" on multiple (sometimes up to 4) control channels.

What would cause this issue?
  • RFI
  • Hardware issue
  • Tropospheric ducting
    • closest P25 site I can find on the same frequencies is in PA, after that TX
    • closet analog site on primary control channel is in SW VA
  • Intentional interference using a high power amplifier that could cover all control channels simultaneously 151.0625 151.1075 151.355
Would be interested to see what you all think... here are some documents I obtained while looking deeper into this.

For the record, I am in no way affiliated with the system or the people who work on the system... otherwise I probably would just call Motorola.. just a concerned citizen and HAM wanting to learn more and more importantly.. how and why this happened.

Not a systems person(there are some absolute geniuses on here who are tho), but it speculatively looks a site went into failsoft, it was voted out by the controller, the issue cleared itself and the network ops cleared it out.

I doubt there was intentional interference or tropospheric ducting that took it out, I'd say some kind of hardware transient at that site. Would need waaaaaaaay more information than what you have here to get to the bottom of this.

Site controller failure is the only thing that will put a radio into failsoft.

The data you attached tells the story. Illegal carriers (interference) on all control channels caused the site to go into failsoft. We can only speculate what the source of the interference was (bad amp in the RXMC, intentional jamming, ducting, noise form a nearby power line arrestor or ???).

Yeah all the Control Channels being failed out would do that as well. I didn't think of that senario.
