[IRCA] SRF-59's Astonishing Nulls

[D1028Gary@xxxxxxx]

Hello All,
 
     Until reading of Kevin's phenomenal accomplishment  of nulling local 
slopper KKDZ-1250 to receive KWSU, I never really paid much  attention to the 
tiny radio's nulling ability.  I knew it could put  almost any local into the 
noise in general, but I when I started experimenting  with slightly tilting the 
unit after the first null was achieved, I discovered  (like Kevin) that you can 
usually get traces of DX stations right on the same  frequencies as your 
locals!  Astonishing...
 
     Having fully disassembled the SRF-59 (interior  photos available on 
request),  I'm convinced this is because of  the 1.75" loopstick's isolation at 
the top of the unit, where efforts were  made to keep it away from components 
that could compromise its nulls.   Contrast this with the SRF-M37V's 2" 
loopstick, which although slightly longer,  is sandwiched between the front digital 
clock/switch circuit board and the rear  RF/AF circuit board.  The SRF-59's 
null's are every bit as  incredible as those of the tilted 7" loopstick-possessing 
ICF-S5W, and  if a DXer is willing to experiment with a tripod-mounted SRF-59 
(as  Kevin has), he may finally be able to zap all his locals with  killer 
nulls.  I'm just starting to experiment with this, but already local  KSUH-1450 
has been zapped to receive Port Angeles, and mega-IBOC slopper  KHHO-850 has 
been zapped to receive Denver.  What will this tiny wonder do  next??
 
                                                                              
                73,   Gary
