To see the RBN, go to http://reversebeacon.net/srch.php Type in N3ND, hit enter. Look for the 160m spots around 03z 15 Nov. The 03z spots are at 400 watts. The 00z spots were at 100 watts, before the band was really open to the SE. RBN's from two other stations in the area were down by similar measure at 00z and up at 03z. This is an up 70, over 60, down 5 wire fed via a feedline isolation transformer against a 5/16 wave single wire folded counterpoise at 8 feet. No radials. There is no way his small lot property could support a dense radial field, either buried or elevated. Therefore, presuming that undense irregular radials that would fit would be excessively lossy, per RBN data previously gathered, the +33, -33 foot linear folded counterpoise (FCP) is used instead, elevated at 8 feet. The folds in the counterpoise are designed to self-cancel fields as much as possible, thereby minimizing ground induction, which is loss to skywave. The 66 foot straight line (more or less, not critical) FCP footprint is much easier to place on property than some miscellaneous attempt at a broadcast standard radial field. 73, Guy. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
