DXPatrol ultra-wideband 0.1-2000 MHz receiver - $99.95! 

New MK4 version released July 2017!

DXPatrol is an ultra-wideband software-defined receiver (SDR) in a surprisingly small package, measuring just 2.875" x 1.75".  It provides full-coverage reception from 100 kHz to 2 GHz (less 800 MHz cellular blocked), using your favorite open-source SDR software via Windows, Mac, Linux or Android.  It plugs into and is powered by your PC’s USB port.  You can use your Android phone or tablet instead of a PC and have a truly portable setup for shortwave and DX listening. 


Listen to signals throughout the radio spectrum using AM, FM and narrow-band signals like SSB and CW.  You can see the radio spectrum from as narrow as 50 Hz to as wide as 3 MHz!  Monitor the entire amateur 10-meter band in one screen. This is a Swiss army knife of SDRs, with applications only limited to your imagination and your software.  Scroll down this page to see the numerous applications for this little gem and where you can obtain freeware software.  To purchase this item or read the manual, scroll to the very bottom of this page.
