Using the RTL 2382U as an Automatic dependent surveillance-broadcast (ADS-B) receiver

          Ive been making good use of my RTL to receive ACARS with ACARSD recently and was looking for something a little more technical. Some googling led me to ADSB# which in turn led me to ADSBScope. Well, i spent 6 frustrating and ultimately fruitless hours of my life trying to get ADSB# to work, no matter what i did, even down to uninstalling the drivers, it just would not work. Then i found RTL1090. What a joy this piece of software is to install and use! RTL1090 is the necessary link between the dongle and ADSBScope, tuning to 1090MHz and providing the data for ADSBScope to plot.
         Both programs are well documented on the net and simple to install. At first i was dubious as to whether the dongle would actually work in the GHz range. Anecdotal evidence says it will, but each dongle seems to have its own intricacies. Fortunately,  the RELWITHDEB zip i downloaded contained a test file that indeed showed it could. (how much more can this great little stick achieve?? actually, i have read that it is possible to modify it to receive below 30MHz!!...but thats for another day).
         The following shots are taken just after i got it running and i have spent a very enjoyable day watching my "RADAR".
