Re: [IRCA] 1134 heard on eton E100

[D1028Gary@xxxxxxx]

Hi Kaz & Walt,
 
     Congratulations, Kaz, on receiving Croatia-1134 on  a barefoot SRF-59-- 
truly an accomplishment in patience and determination (and  qualifying for a 
nice First Ultralight TA award from John Bryant and Rob Ross,  should you feel 
so inclined).
 
     Unfortunately, the SRF-59 (and SRF-39FP) has a  bizarre IF that is not 
amenable to any filter upgrades that we are aware of,  including the Murata 
CFJ455K5.  The IF is around 50 kHz, and in processed  inside Sony's proprietary 
CXN1129 IC chip.  I have personally transplanted  many large loopsticks into 
these analog radios, which manage to boost  sensitivity, but also degrade 
selectivity.  For this reason, they are not  really suitable for DXpedition work, 
like the 455 kHz IF E100's (which can be  boosted greatly in both sensitivity 
and selectivity).
 
     73,  Gary DeBock

Don't know.  It is a very simple receiver, so  one should think it's 
possible.  Gary, John, Guy?.....Walt.
PS:   I did pick up a talking house on 1650 about 8 months ago on the  
SRF-59....about a mile away from my  place.
