Hi Colin and Kevin,
The Sony ICF-SW7600G and GR models have a serious image issue 910 kHz
below strong locals, but the loopstick is a non-alignable type like that of
the ICF-2010, meaning that a Slider-type loopstick is not a possibility to
correct the congenital image problem. Almost all other traditional BCB DXing
portables (RF-2200, ICF-S5W, etc.) with image issues can have the problem
corrected or minimized by the use of a Slider loopstick, or tuned passive loop
antennas (which can help minimize image reception in any receiver).
Both the ICF-SW7600GR and the ICF-2010 benefit greatly from larger
transplanted loopsticks, however. Sensitivity is greatly boosted, with no
apparent negative effect on selectivity. But the images and spurious signals
are
also boosted, since the larger transplanted loopsticks have nothing like the
Slider's ability to tune out these nuisance signals.
Colin, KONP-1450 in Port Angeles must have a fantastic salt-water
transmitting site, because I have even received it here in the null of local
slopper KSUH-1450, during rare night conditions. It was a very satisfying
psychological victory, to receive another station right on this foreign
language
Mega-pest's own frequency :>)
73, Gary
