Software-Defined Radio (SDR) on an Android Phone

A software-defined radio system, or SDR, is a radio communication system where components that have been typically implemented in hardware (eg mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded computing devices.[1] While the concept of SDR is not new, the rapidly evolving capabilities of digital electronics render practical many processes which used to be only theoretically possible. (see more goo.gl I used a Samsung Galaxy 2 with gISDR Android app by Alex Lee Shing Cheung for a test, and found very good result. Actually, the app require SDR service from a server which selectable from the app. There are features that can be found on the high-end HF receivers such DSP, Filters, Modes, Band, Scope etc which work well on my phone. You can try this free app from Google play, amateur radio catagory. Have fun!
