My new Hyperflex 5 Crystal Low Loss Cable from Bonito for best receiver connection.

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)

My NetModule NB 1600 industrial mobile broadband router. Connected wireless without any problems since 5 years. The life insurance for your remote station.

Better grounding for my Beverage Boxes with solid copper strap: now 5 dB lower Noise Level, every dB is important… Difference between the two SDR recordings: 15 min.

Interesting first (audio!) review from Nils Schiffhauer (DK8OK): It has been dubbed “game changer” and indeed, the Airspy HF+ is a completely other animal of software-defined radio, or SDR. Link: https://dk8ok.org
