I received the SDR-IQ over three weeks ago and have been having a lot of fun with it. The ability to visualize the spectrum really changes the way I listen to the radio.
One thing I noticed, though, is that my two local AM stations (1 kW @
1 mile, 5 kW at 3 miles) both show up as "images" at +/- 196 kHz from the fundamental frequencies. These images are down about 60 db, but that puts them at about the same signal level (-90 to -100 db) as most of the other stations I can pick up.
I posted a message to the SDR-IQ group on Yahoo but haven't heard from anyone else whether my experience is unique. More on this if I uncover anything new.
