I have heard noise caused by tower climbers rubbing two metal objects together near the antenna. > and the weird noise that is initiated by keying the APRS, but > won't leave until the voice repeater is unkeyed has me scratching my head. > The repeater might be getting into the PA stage of the APRS radio.
