what about sweeping with a soundcard?? it should be possible to use line out and line in (or mic in) and use a soundcard like the nanovna (just ab idea from a dumb nut) sg9bfc sigi Am 13.12.2024 18:33

to surpress ground current just turn the usb cable a few turns around a ferrite core (bigger donut shape) that should work well enough dg9bfc sigi Am 03.12.2024 07:55 schrieb "Ismo Väänänen OH2FTG via

a sidenote.. best results are with using two 100 ohm resistors.. from centre pin to left and right .. better as using a single 50 ohm Dg9bfc sigi Am 01.12.2024 10:45 schrieb "tom Kawala via groups.io"
