Hi Clemens, In my application i use it to decouple my 2 orthogonal VLF loops from the soundcard and do some "matching" of the low output impedance of the loop to the high input impedance of the sound
Hi Stefan, Look for A262A1E from Walters OEP http://www.oep.co.uk/ Fully screened and low interwinding capacitances - but rather expensive. Frohe Ostern, Peter, df3lp
Hi Stefan, I have measured exactly this transformer about a year ago for a friend. He tried it for a (meanwhile abandoned) soundcard based SDR- TRX project for HF and failed due to lack of sensitivit
