I installed gnuradio and my understanding is that I need some minimal hardware, presumably USB dongles. After some search I found several vendors - RTL-SDR. HackRF, AirSpy, etc. I found https://forums.freebsd.org/threads/rtl-sdr-on-freebsd-or-hey-cool-i-live-near-an-airport-i-wonder-if-adsb-works.52157/ and it says RTL-SDR is support by FreeBSD. My father who is a radio engineer asked me to find him such a hardware. He is a Linux user and my impression is that those devices are supported on Linux. I found the topic interesting enough to buy one for me and as a FreeBSD user I want to use it on FreeBSD. What other recommendations can you give me about such chips? What to buy, where to buy? I am looking for cheap ones - something up around $100. Will I need any drivers for FreeBSD? Regards rambius -- Tangra Mega Rock: http://www.radiotangra.com
