For practical reasons it may be better to have a separate receive antenna. Many OMs worldwide use a PA0RDT antenna. You will find it in the web. This works from a few kHz to a few 10 MHz.

Hi Stefan,

=A0

nearly every eve= ning i talk to Ewald DK2DB.

He told me one evening from his success to read two stations on 600 Meter.

I think my amate= ur heard told me to try this.

I am from the beginning of my amateur business always interested in new things.

Things I have ne= ver tried before. So I tried to receive 600 Meter signals.<= /p>

Rig is now an Ic= om IC-7600. Using an end-fed 40 meter dipole.

The result was v= ery bad due to much noise.

Then I started t= o get better results. I put a good ground to the IC-7600.=

From this time I could receive some signals. Also on 136 KHZ.

Your signal is always good to receive here in JO61PB near Dresden.

In the moment I = am looking for better antennas. May be some one here

can help me and = tell me which type of antenne I can use here.

As am am very ne= w on these very low frequencies I need much help hi.

=A0

So hope to hear = you very often.

73 und good cont= acts on these low frequencies.

Hi Uli,

It is always 136.172 kHz when running slow QRSS/DFCW for me. BTW the DFCW shift is only 75 mHz, so you will see no shift when not correctly setting the spectrogram.
See http://www.a= lice-dsl.net/df6nm/grabber/Grabber.htm to view the signal.

A grabber overview is here: http://wireless.org.uk/grab= list.htm

The D is already sent ;-)

73, Stefan

PS: Are you a newcomer on LF? If so, what triggered your interest in the real low frequencies?
