How this works does not take a degree in rocket science.
A member of our TruthOrFiction.Com Team is an amateur radio operator who
said that touching the radio control key device to your head will
improve its performance because the body has becomes the antenna for the
radio transmitter. This is similar to the effect you get
when adjusting the rabbit ears of an old TV set and noticing the
reception improves until you walk away from the set.
Doing this is safe and will not harm the body as the transmitter power
is very low. It is no more harmful than using a mobile telephone.
