DXPatrol ultra-wideband 0.1-2000 MHz receiver - $109.95!
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.
