The big issue now is the antenna. My first thought was a kind of a T( top hat)-antenna, but I have a loop antenna about 80 meter in circumference and 6/7 meter above the ground . What about using the loop as a capacity on the top of a vertical or using the loop as an ordinary loop antenna for 600m ? -- LA5VNA Steinar loc:JO59jq Mal and spam filtering: STRONG www.opera.no
