Re: [IRCA] Slider Loopstick Cancels Out Image Reception

[D1028Gary@xxxxxxx]

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
