[IRCA] Tecsun PL-380 DSP Selectivity Demonstration MP3-- 738-Taiwan

[D1028Gary@xxxxxxx]

Hello All,
 
This morning's TP reception included a strong signal from 738-BEL2 (Taiwan  
Fisheries), providing a chance to record the new Tecsun PL-380's DSP filter 
 options during actual TP-DXing.
 
The recording linked below has the PL-380 receiving 738-Taiwan at 1443 UTC, 
 in the face of some splatter from 740-KCBS in San Francisco. The MP3 
starts  with the PL-380 on the 2 kHz setting (for the best combination of audio 
and  selectivity), then steps briefly down to 1 kHz-- followed by 
approximately 5  seconds in the 6 kHz, 4 kHz, 3 kHz, 2 kHz and finally the 1  kHz DSP 
filter options. This recording was made with a signal boost  provided by an 
experimental 9' sided PVC box loop.

The recording is dramatic in showing the effectiveness of the 7434 DSP chip 
 in providing outstanding selectivity (for a $45 radio). Hopefully it  will 
be of interest to prospective purchasers.
 
73, Gary DeBock (in Puyallup, WA)
