Thanks for the IC-2820H antenna socket advise. Diversity is the word I heard and didnt understand. I have now downloaded the manual, but not seen a full explaination of it. Just so long as its not vhf in one and uhf in the other. All my antennas are dualband :) cheers guys Jack VK2CJC / MM0AXL www.qsl.net/vk2cjc
