On mine I find that the power supply switch must be on to connect the antenna to the radio. Same here. 73 Rag Otterstad LA5HE also JW5HE OZ8RO located in Telemark - home of skiing. My antenna "farm" can be found on HTTP://no.photos.yahoo.com/la5he when you click on Radio. Take a look at: http://WWW.visitTelemark.com or http://www.visitnorway.com
