DREAM DRM SOFTWARE AM DEMODULATION Homemade Down Converter for radio receiver on PC

Today I re-started the experiments with SW Dream.
After my small laboratory was destroyed by a flooding river....
no frequency counter, no oscilloscope and no signal generator ...
I have to buy new ... so I can not make precise measurements....
I built a simple down converter with integrated circuit NE602 and the ceramic resonator filter at 465 kHz ... see this link: http://users.belgacom.net/hamradio/schemas/DRM_455kHz_to_LF_Converter_FRG-100....
The first test I did it by connecting an old receiver OC, home made, of NUOVA ELETTRONICA (LX1532....)
This is a double conversion Super Eterodine radio. http://www.nuovaelettronica.it/
I connect to the output of the second intermediate frequency of 455 kHz.
The PC is very old, Pentium 3, 1000, with 512 MB ​​of RAM and may be too slow ... but I think the initial results are positive. CPU run at 78%...
The received station today is: Studio DX, 15 May 2011, approximately at 11.18 Italian time.
On air in AWR EUROPE, SHORTWAVE BAND,
RADIO VOCE DELLA SPERANZA - Sunday - 09:02 UTC 9790 kHz
Frequency Verified with other radio digital frequency and on the Internet
