Does anyone know of a modification for the KW Matchbox that would allow it to operate on 160 meters? I ran into a ham recently who suggested that such a modification has been published but could not recall when or what the details might be. I feed 80 and 40 meter dipoles on a common center insulator with open wire. Would like to use them on 160 with the KW Matchbox. Any chance? Thanks. Steve K8JQ
