And btw comms/rtlsdr talks to the stick directly i.e. not via the Linux dvb drivers run by webcamd; I need to temporarily unplug my stick before webcamd will work again for it after I used it for sdr... HTH, :) Juergen PS: There are a few more rtl28xxu sticks listed on the wiki that I tested for this: (look for rtl28xxu) https://wiki.freebsd.org/WebcamCompat And there are longer lists here: (comms/rtlsdr is the same as used on Linux so they `should' all work as indicated) http://sdr.osmocom.org/trac/wiki/rtl-sdr and: http://www.reddit.com/r/RTLSDR/comments/s6ddo/rtlsdr_compatibility_list_v2_work_in_progress/ PPS: If you just want to listen to shortwave or mw as received from the Netherlands and don't have an rtl stick + downconverter there also is websdr that just works in a (recent enough) browser w/o extra hw: http://websdr.ewi.utwente.nl:8901/
