Not a precise freq. My accuracy is plus/minus a couple of hz and aroun=
d 8970.
But like Andy has said even direct use of sound cards and lack of prop=
er software is no guarantee to see a signal at rediculous narrow bandw=
idths. Even locked to a freq standard accuracy is hard to maintain in=
 the uhz domain, its a hit and miss game both at the RX and TX end, pl=
us the very long time period and then no real ID in the end. Confirmat=
ion confirmed by frequency alone is not valid.
When I copied OE5ODL I asked him to cut carrier for ID, this he did an=
d I was able to confirm the transmission was from him, I also copied=
 him here in QRS 30, 10, 3 mode which is more realistic instead of wai=
ting hours and weeks.
I hope u see my point.

  Hi Mal

  What was the precise frequency and time of your test please? I can=
 look again at my screen grab if I know where, but I have to look in=
 very narrow bandwidths for some hours to make out anything distant on=
 VLF.=20

  BTW, your Spectrum Lab bandwidth looks very wide and although this=
 may be OK for the stronger stations you will have to use MSK locking=
 or similar  and much narrower settings to see G3XIZ for example. I kn=
ow you are less keen on this sort of testing, but Chris would apprecia=
te a report from you I am sure. Also, you would be much better with di=
rect reception on VLF rather than mixing up first as this is another=
 source of frequency error best avoided when searching for weak signal=
s with narrow FFT settings.

  Good luck and keep looking!

      Will that be the 3-el triband Mal?

      More seriously, people do appreciate you looking. Keep at it and=
