I have 2 USB Dongles for SDR receive here. I have never been able to get them to work properly in windows (none of the windows coded SDR software programs are usable by the blind) and I have yet to try them on my Mac mini (only have 4 USB ports and 3 of them are already in use). These devices are RTL-SDR types (cheap) and 1 will operate down to 100 Khz and up to 30 Mhz. The other will operate from 25 Mhz to approximately 5 Ghz (although it won’t be nearly so good above 3 Ghz). Btw, if you want a couple of bands of interest below AM broadcast, try 472-478 Khz and 173 Khz. Both of those are recently opened allocations. -Eric > On Jul 4, 2018, at 11:29 AM, Steve Litt wrote: > > On Wed, 04 Jul 2018 09:34:41 -0700 > Eric Oyen wrote: > >> Well, Linux shows up in many places that most Linux users never >> consider.
