Gate seriesresistor is 1M to prevent im from MW stations,inputimpedance is 500M.In the output I use an isolationtransformer and a passive double-T notchfilter at 50 hz to prevent overload from the soundcard (Soundblaster audigi). 73 Victor PA3FNY -----Oorspronkelijk bericht----- Van: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org]Namens Scott Tilley Verzonden: donderdag 2 juni 2011 16:00 Aan: rsgb_lf_group@blacksheep.org Onderwerp: Re: LF: Schumann Hi Victor / Eddie What are you guys using as your antenna for this?
