Thanks for your comments, Nick. As we discussed earlier, the "short and stubby" antenna design proved to be the key for breakthrough pest nulling-- as long as everything is kept perfectly symmetrical and isolated. The design of this new 4.25" FSL was simply a mathematical re-design of an earlier 3" FSL made with the 62mm ferrite bars-- increasing the diameter but reducing the number of turns. As it turns out the weight and ergonomics of this new "pest control" version is about the same as the "article version" 3" bar FSL-- which is reasonably convenient and suitable for portable DXing as long as suitable care is taken to avoid accidents. The weight of both the PL-380 and attached FSL is still much less than a full-sized portable like the ICF-2010 or ICF-S5W. This morning it was tough to go to sleep after the all-night session, with semi-locals like 570-KVI, 950-KJR, 1300-KKOL and 1360-KMO all biting the dust completely to allow competing stations to be heard right on their own frequencies.
