Stan, If that "hand effect" occurs while transmitting, then it can be attributed to RF-in-the-shack. The only cure for that is to work on your antenna system. If your transmitting antenna is close to the operating position, there may be no real cure. OTOH, if the transmit antenna is not coupling directly into your operating position, that may be an indication that RF from the antenna is being coupled back into the operating position - the use of baluns or transmission line chokes, or effective RF Grounds (try a 1/4 wave "counterpoise" wire) would be means to minimize that effect.
