So, what the heck did you and he say? I am unfocused? Undisciplined? Unable to use the force? Should I be more interested in this?
What is it that you are telling me?
RF Touch lamps are RF-operated devices that often cause, or are susceptible to, EMI problems. They have a free running oscillator that is very broad and rich in harmonic energy. This oscillator is hooked up to a touch plate that changes the frequency of the oscillator when a hand is placed near the plate. Unfortunately, this plate also acts as an antenna, radiating some of the energy of the oscillator, or picking up nearby radio signals. When the former happens, it can interfere with other services. When the latter happens, the circuitry inside the lamp reacts the same way that it would when the plate is touched -- the lamp changes states from "off" to "on".

Ever have a TV with rabbit ears? A portable radio with an antenna?
Know how sometimes touching the antenna or rabbit ears can change (improve/degrade) the reception? Sometimes just moving near the thing can cause a change.
