[IRCA] "Super Prison Radio" Outperforms ICF-2010 in JOIB-747 Reception

[D1028Gary@xxxxxxx]

Hello All,
 
     The experimental SRF-39FP Ultralite radio (with a  transplanted 6.25" 
loopstick, fully described on dxer.ca)  has  received its second TP this month, 
again with signal quality superior to  that of a fully-aligned ICF-2010.
 
     Tuning the band and finding many strong TP hets  around 1455, KXL-750 
was tuned in and nulled, producing a decent signal from  JOIB-747 after further 
slight tuning. The ICF-2010 was checked, and in a repeat  of the JOAK-594 
reception on 2-12, the ICF-2010 had the Japanese  station's audio also, but at a 
clearly inferior level.
 
     A full daytime shootout between these two top  portables was held on 
Sunday (results available upon request to anyone  interested), which showed that 
the "SPR" had a clear edge in sensitivity up to  around 800 kHz, the ICF-2010 
had a slight edge from 1000 to 1600, and the SPR  again had better sensitivity 
from 1650 to 1700 kHz.  Of course, the SPR can  only compete with the 2010 in 
sensitivity-- it cannot compare with the ICF-2010  in selectivity, SSB, synch 
detection, memories, etc.
 
     The only instance of total dominance in the  sensitivity department was 
the SPR's superiority in the 530-700 kHz range, where  it actually received a 
couple of very weak stations that the 2010 had no trace  of.  In this lower 
frequency range, the Super Prison Radio was just  about putting the ICF-2010 "in 
jail," hi..
 
                                                                              
           73,  Gary DeBock
