Content preview: During a very pleasant meeting with Chris 4X1RF and his family, we discussed possibilities of improving the noise situation for LF here in the Kibbutz. Chris suggested to replace the low active antenna by a passive long wire and a separate earth. Walking through the village with "open eyes", today I managed to find some 30 m of old unused telephone wire which was thrown over some branches, using fallen grapefruits as casting leads. I could also salvage a ferrite choke from a discarded TV power supply, which now serves as a common mode choke to separate the earth connection from the notebook supply. Comparing HGA / DCF before and after, it looks like the SNR has dramatically improved by some 10 to 15 dB.
