Re: [IRCA] Strong Chinese on 657 kHz

[D1028Gary@xxxxxxx]

Hi Bruce,
 
Thanks for your comments on the 657-China reception.
 
Actually, many of the high-band AM loggings that you report from Seattle  
(with your K9AY antenna) never make it to audio here in Puyallup at my 
location,  and the same effect is noticed even with Guy Atkins' high-band AM 
loggings  only about 4 miles SE of here. On the other hand, I can occasionally 
receive  many low-band Asians that Guy has no trace of, even when we listen at 
 the same time, on the same frequency.
 
I think the reason for the disparity is related to the unusual 9'  box 
loop's reception pattern, in which the highest "Q" is obtained on the  lowest 
tuned frequencies. This creates a situation where the giant 9' loop is  a real 
overachiever from 531 kHz to about 891 kHz, about  equivalent to other 
high-gain antennas on the middle frequencies, and maybe  less impressive on the 
upper-band.  One example was the reception of  the 594-KBS1 station here 
last December, which apparently Patrick (and  the Grayland DXers) had never yet 
come across.
 
73, Gary

I played your file and then replayed my SDR file from the exact  same 
time. What a difference!  Mine was nowhere near as clear as what  you 
recorded. I could tell someone one was talking on 657 in the 660  
splatter, but it wasn't good enough to determine the gender of the  
speaker or the language being spoken.  Sometimes it's hard to believe  
we're only 40 miles apart.
