Dear Stefan, LF Group, Which vertical antenna do you mean? 73, Stefan/DK7FC Well, on 15/05 you wrote: If the wind is stable and i have enough time i will do first receiving tests using the TX antenna! This >is to prepare the first VLF QSO above 100km ;-) I was just curious to know if you tried this, and if so, how loud the results were... Back in 2000, I did some tests on 136k and 73k from the 100m high Decca Navigator mast at Puckeridge. The receive SNR was actually very good, thanks to the quiet rural location, but it did need about 40dB of attenuation at the RX input. Cheers, Jim Moritz 73 de M0BMU |
