I use the circuit of M0BMU with the bandpass= filter of 9=20 khz...
also the loop resonates on 8.97khz
 
as i understoot the attached file you sent me= is used to=20 lock the samplerate with the 19.58 GBZ signal??? if yes  then i= dont think=20 it will work.
 
I think its ok to work with your 9kHz_4mHz.usr= and leave=20 the pc some hours to run on grabbing before the start of transmissions= ...=20  in order to stabilize
 
my sound card is delta-44
 
also i made a batch file upload_vlf.bat=20 (for 9kHz_4mHz.usr) file that has the following code
 
@echo off
echo %DATE% %TIME%
set=20 MTH=3D%DATE:~4,2%
set DAY=3D%DATE:~7,2%
set YR=3D%DATE:~10,4%set=20 HR=3D%TIME:~0,2%
set HR0=3D%TIME:~0,1%
if "%HR0%"=3D=3D" " set= =20 HR=3D0%TIME:~1,1%
set MIN=3D%TIME:~3,2%
set SEC=3D%TIME:~6,2%set=20 MYDATE=3D%YR%%MTH%%DAY%-%HR%%MIN%%SEC%
copy vlf.jpg %MYDATE%.jpg
 
the result is to copy each time the vlf.jpg as= file with=20 timestamp
eg 20101505-232042.jpg
 
so when I will return back home I will not mis= s anything=20
