USB Galvanic Isolation.

Next step for reducing “home made” QRM from my PC/SDR connection: My new Intona Technology USB 2.0 High-Speed Isolator. This product is an solution to break ground loops, avoid noise coupling and protect ports from power surges and voltage spikes. It works “High-Speed” without any problems also in 4 MHz spectrum recording with my WinRadio Excalibur G33DDC. Again 3-4 dB noise removed! (yellow without, green with Isolator, time difference two minutes, “empty” MW-Band for better visibility, 20 mt. Loop with Bonito ML052 amplifier)
