Dear Stefan, LF Group,...>300 Ohm earth+surroundings losses is very good compared to my values on the hill, although i have just one small tree in a radius of >100m. What about your ground conductivity?....> The ground here is clay, with a high water content, so conductivity is probably high. The earth system was 4 - 6, 1m long, ground rods, spaced a few metres around the feed point. ...>Will you prepare a TX system on the dreamers band as well? Than we could repeat our CW QSO just like on 137kHz ;-)...> Based on the experience of the last few weeks, in order to achieve anything more than very short range communication, it will be neccessary for me to use the /P site I have used for the receive tests for transmission also. This requires some diplomacy with the owner of the site, who is one of my relations. I am working on it... Cheers, Jim Moritz73 de M0BMU |
