Time to fix some of this. Record and then jam their tinker toy signals next time and inspect lecterns for hanky panky.
I think that box inside the podium was a special relay receiver/transmitter designed to defeat jamming attempts. If the channel they were using detected interference, it would automatically shift to another channel. Only a broad-band jamming device would have been able to knock out the signal. Then other things like wiFi and the wireless mics would have stopped working. People would look for the source of the interference and that would be trouble.
Wouldn’t it have been fun if a Trump rep. showed up with a dolly right after the debate and wheeled off Hillary’s specially built podium for inspection. Too late, now, but maybe next time.
