Rik, in parallel to R at the input of some soundcards. I can confirm this. I've digged out a VNA plot (starting at 5kHz) of my onboard soundcard. You can see that at 10kHz Z is around 3kOhm, R 2,5kOh

Assuming worst case,10kOhm for the soundcard, you had a maximum mismatch loss of only 0,9dB,which is totally neglegible,particularly on LF. Sounds good! 73 Clemens DL4RAJ -- Original Message -- From:
