Hello Gary, Tony, VLF,

Yes, you can use Markus' files for reception. It is suitable for the detection of a long carrier, say 30 min.
If you want to copy my DFCW-600 letters (10 minutes per element), you may use the attached file which runs faster. The samplerate drift is compensated by locking to GQZ/22.1 kHz. A filter, clipper and noiseblanker is applied.

Hi Tony,

If you go to Marcus's grabber at :-


You can download his SpecLab 8.970khz *.usr configurations from a link at the bottom of the grabber page. You should find them useful, I have.

 Hi Stefan.

I have a Vigilant Systems HF surveillance radio that is specced to 10 KHz, but seems OK(ish) to 6 KHz.
Also I have just built Jim's (M0BMU) sound card pre-amp that I shall play with tomorrow.

Antennas are inverted L (15m^ -30m>) plus my pair of 80m long earth electrode antennae N/S & E/W

Not got to grips yet with computer software, using Spectrum Lab as it comes out of the box

Hi Tony,

Thank you.

I am looking forward for that! Our distance is 1310 km (pic attached).

Pse, what is your complete RX equipment? Do you have the settings for DFCW-600? Any noiseblanker and/or clipper in use?

I have made a mistake: On Thursday i have to decide about saturday...

Tomorrow and Saturday they are working on the power lines here and there will no electricity within 10 miles of my shack.
Should lower my noise floor a bit.
