If the GOP were smart, and I’ve seen no evidence of that - based on who they allow to be “moderators” - they would continually broadcast a sharp electronic signal to counter any cheating of this nature
They'd have to know the specific receiving frequency which could be determined with an antenna hooked up to a frequency counter. Every time she received a transmission the frequency would be detected. What would be "more" fun though would be use a ham radio tuned to the same frequency and let everyone hear the signal she's receiving during the broadcast without her being aware she's been caught...lol
