Hi All,

Ed, RU6LA, received the following Email from YL3DW and since it will be yet another country on LF, with what looks like a potentially big signal, he has asked me to translate it and post it to the web.  It is a little lengthy but interesting. I will leave comments to others. The translation follows.

John, G4CNN


Good day Vlad,

I was not really a fan of LF, in fact I didn't really  believe in the possibility of long distance reception at this  wavelength in the situation in which the majority of hams find  themselves.

>From all the information about what is happening on this band, I have only seen one article in the Shortwave/Ultra Shortwave by UA9OBA and an article by a G3 in QST. Nevertheless in response to a call from a colleague on the NZ Reflector, I decided to try to  follow the work of your group.


An attempt to hear RU6LWZ at the time of the first expedition proved  fruitless, that is apart from a mass of 50Hz lines nothing was heard. My IC775DSP was working against a high level of interference on this band, with an unmatched antenna, in short everything was  wrong and so there was nothing to hear.


Somehow I didn't feel up to diving into this transceiver to make it work on this band like the Kenwood TS-850. Nevertheless for the sake of curiosity, I thought I would see what  would happen if I simply improved the selectivity of the receiver by putting a preselector ahead of it. I was too lazy to read up and get out the soldering iron, so I took a multiband measurement filter F1 (so called, which can be used with the GSS to obtain a pure sine wave and has 10 bands from 0.1 to 10MHz) and simply connected it between my 160 dipole and the receiver.


It turned out that this filter not only filtered but considerably improved the matching of the antenna to the receiver especially in the range 135 - 138 kHz, and the level of signals on the scale of my S meter increased by 20dB.Encouraged by this result, I decided to undertake a second attempt to hear RU6LWZ on the following saturday. And in fact, in the region of 137.7 kHz heard an almost imperceptible signal which didn't look like a harmonic of 50 Hz. But what or who it was I could not dare to say. I became quite sad. Furthermore a lot of european sources in the cluster were heartily lamenting the fact that RU6LWZ was breaking through everywhere. And I was quite destroyed by Sergei's, UR5MID,  communication to the NZ reflector that he could hear RU6LWZ at home, God knows by what means (he didn't say).


I would have spat at this LF DXing and signed myself into a lunatic asylum if the same Sergei with the usual surprised Oh's and Ah's had not also sent in screenshots in which the call-sign  could be seen in the form of dots and dashes .Having looked at all this for quite a while I called myself a fool for having ignored the fact that the great mass of QSOs on this band take place in QRSS. Carefully looking at the image sent in by UR5MID, I saw that it was received using Argo version beta 1 build 128. Straight away I got into GOOGLE and found I2PHD's site, the existence of which I hadn't even suspected. I quickly downloaded and started the program.


I looked at the screen and Oh...like a bolt out of the blue, in the region of 137.7 kHz a pile of stations calling separated from one another by 10 - 20 Hz. I was clearly able to read M0BMU, OH5UFO, OM2TW, IK2DED, HA6PC, DF6NM, OH1TN, and right in the middle of this pile-up the bright fat line  of RU6LWZ.


The Finns didn't surprise me, Yura YL2DX had told me that he had heard a CQ from OZ1KTR on 137.

But the others ..... after my 27 years on the ether, I thought I had seen and heard everything, but such a feeling of euphoria. I shook from excitement. It was  like when you first see that a whole new field is opening before you.

I really got keen on Ham radio in 1975 when I made my very first QSO. For the very first time in my life no longer was I just an observer. I sat all night till the very next morning. After which feeling just as after a very successfully worked contest.


 I almost fell of my chair, when about 2200z in the headphones I heard CQ RU6LWZ with RST 559-579, I thought I was imagining it. Just before dawn about 0600z I again heard a CW CQ, but much weaker about 539-549. A clean clear signal without QSB, about 6dB above the background according to the S meter.

Concerning QRSS, if one can believe the level shown by ARGO the picture according to the level of signals looks like this:


background noise level -55 dB

50Hz harmonic level -40 dB

RU6LWZ/RU6LA -20db 

M0BMU -24db 

OM2TW -26db 

OH1TN -30dB 

IK2DED -35db 

HA6PC -40db 

IK5ZPV -45db 


These were the very strongest stations. There were other weaker stations, but I won't list them all.

Of course the relative strength of the signals changed with time, but I can definitely say that RU6LWZ was very much the strongest at all times.

These were all measured with an unaltered IC775DSP, sloping dipole for 160m connected by 75 ohm cable to form a dipole and not a T antenna.

One end of the dipole is raised to a height of 80 metres and the other to 50 metres above ground. The dipole runs parallel to a high-voltage power line 300 metres distant and at a height of 50 metres.


All this has caused me to think hard about how to work on 137 and about a transmitter.

In principle it is possible to set up a large loop with a side of 100 metres and a height of 50-70 metres above ground. However there is one problem - wire. If I can find enough, then I will try it. This is from home. If there is enough time and I can manage to encourage some others, then in the summer we will try to work seriously on LF, it so happens we bought a 200 metre mast, but we have not yet managed to raise it.

73 and success with LF experiments,

Oleg YL3DW/YL9W/YL4U captain of YL4HQ.
