Re: LF: Which QRG

[Ulrich Wandel <newsgroups@dj7ka.de>]

Hello Stefan,

in the moment i dont plan to transmit on 630 and 2200m

i like to be an SWL.
i dont know how good or bad the IC-706 is, but my IC-7600 is really good and i dont have Problems with strong am BCD stations.

I think i have to lokk for better grounding my station.
I got somethings like the PA0RDT antenna from Ewald DK2DB.
Dont know in  the moment when i can bring it out.

So 73 again and good luck.

Hello Uli,

That is very nice to hear. Be sure we can give you advice from here!
Do you plan to transmit as well, on 630m or 2200m?

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. You are relatively close to DCF39, so it is good to check if the antenna becomes overloaded. Use a completely separated ground. It is worth to test different grounding methods. But i recommend to spend a separate antenna ground rod, far away in the garden. Place the antenna far away in the garden and above all trees.
From the decode levels i saw in your WSPR spots i think you can gain at least 10 dB without to much effort, rather 20 dB SNR.
I don't know much about the IC-7600. Does it handle the strong AM BCD stations on MF or does it behave like the IC-706? :-)

73 and thanks for the reports on all bands.

Hi Stefan,

 

nearly every evening i talk to Ewald DK2DB.

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

I think my amateur heard told me to try this.

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

Things I have never tried before. So I tried to receive 600 Meter signals.

Rig is now an Icom IC-7600. Using an end-fed 40 meter dipole.

The result was very bad due to much noise.

Then I started to 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 new on these very low frequencies I need much help hi.

 

So hope to hear you very often.

73 und good contacts 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.alice-dsl.net/df6nm/grabber/Grabber.htm to view the signal.

A grabber overview is here: http://wireless.org.uk/grablist.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?

Hi Stefan DK7FC,

 On which QRG will you be in DFVW-180
DIAL ??????
