RTL-SDR at 80m with Homemade VEE Antenna and Butterworth Filter

YouTube user VoiceOfShortWave has posted a video of his rtl-sdr dongle receiving HF LSB ham radio transmissions at 3.7MHz with excellent performance. He used a homemade VEE antenna, and also a Butterworth filter to help reduce FM band interference. His other video shows the effect of his butterworth filter with 60MHz cutoff turning on.
