I have a very early home-brewed PAW, subsequently 'bridged' and 'pi2b'ed'.
Works well but the dvb / ADSB dongle has always run hot. I would guess the new low power ones don't. Can I swap to one of these, or is there an alternative (commercial sdr dongle) option?
My PAW is installed with some external antennas so I don't think I need to do a wholesale rosetta upgrade.
