Not working well in New Zealand. I've been using this for the past few weeks to listen to VHF/UHF commercial communications, VHF Air Band and the 1090MHz ADS-B info used by air traffic control. I didn't expect much since there were no filters or pre-amp on the front end, but each iteration of my listening set-up has brought in weaker and weaker signals. Getting the unit in to it's own metal box and shielding the incoming USB cable cut out a lot of the computer noise, then putting a BNC antenna connector on the back let me connect the unit to a radioshack dis-cone antenna for even better sensitivity. ADB# and GQRX are both excellent free programs that work well with this unit. I'm using a cf-29 toughbook computer with windows XP... the audio was spotty at first, but then I added a USB 2.0 PCMCIA card and with the dongle plugged in there, the audio is great!
