DroidPSK is an application to decode and encode Ham Radio BPSK31. A great tool for portable Amateur Radio PSK operation.
DroidPSK is able to decode a BPSK31 signal though the build in microphone. Just hold your Android phone or tablet close to the speaker of you Amateur Radio transceiver, adjust the waterfall slider to the PSK carrier frequencies and DroidPSK will start decoding.
