Hello Mal,

I´m rather impressed by your success on receiving. Seems I am far behind you. However, it might depend on the noiselevel. Here, next to Mainflingen, the noise is -90 dBm with BW=100 Hz in the noisegaps. Antenna is umbrella 23m high with 325 pF on the top. How abt the noise on your side?

It seems to me that I had better results with a marconi only 12m high and only 120pF on top. With this antenna, for example, I did copy G2LDO audiable. Not so with a loop of 1.8m diameter, grounded or ungrounded.

Hi Peter

Nothing magical here but I do live out in the country where the ambient noise is low. I have published details a few times here about antennas and equipment, you have probably seen the info. I often get emails mostly private about what I can hear or see when others around EU and UK struggling. I often notice several EU stns calling CQ both on CW and the QRS MODE but they appear not to hear/see each other.

For most they are stuck with their QTH noisy or otherwise and make the best of it. I fortunately have plenty of LF antenna space and a quiet location both here and in GI land.

I have never used small diamater loops so cannot comment on performance. My smallest loop is 80 metres perimiter and performs very well. It is orientated for max pickup E/W, with this loop and my vertical I can hear/see all the activity on LF that is going on, in fact I have too much gain and have to attenuate hi. I have a larger loop 250 metres perimiter some distance away in the same plane but it is not necessary, I do not need the extra gain so do not use it, to date there is no advantage, because my receiving equipment is sensitive enough with the 80 m loop or the vertical.The loop antennas give an advantage over the vertical when the QRN is bad.

Tnx for the interest and your info

Last nite OK1DWF and YU7AR seen CQ on QRS mode. Both stns good audible sigs with me. They did not appear to work each other at my observation times. Had they been on CW norm mode I would have called but I only use QRS as a last resort. All stns active so far around EU on QRS plus VE,VO and RU6LA, RN6BN and UA9OC are audible with me at Q5, in fact UA9OC was good copy with me earlier on in the year on norm CW when others were struggling on QRS.

The problem with most seems to be RECEIVING, high power TRANSMITTING is one thing but does not help on RX.

Good RX antennas seem rare.

Often several stations are active at the same time especially on QRS calling CQ but seldom reply to one another, or maybe they do not want to work each other!!
