Morse Decoder can be used by Ham Radio (Amateur Radio) operators or anyone else interested in decoding Morse code from a Radio or any other device.
Morse Decoder includes a "waterfall" to show a frequency spectrum of about 50Hz to 2300Hz. A narrow band DSP filter can be set for the frequency of the Morse code tones by tapping the waterfall. The DSP filter is followed by an automatic gain control (AGC) to compensate for changing signal strengths.
The detected signal will be shown as a graph and several algorithms will then detect the speed of the Morse code and convert them into readable text. Speeds of less than 4 Wpm (Words per Minute) to more than 50 Wpm can be decoded.

This is the first version of Morse Decoder.
It has been tested on several Android devices and it performed very well or even better than PC based decoding software. However, since we are not able to test the performance on all 150+ Android devices there is the possibility that Morse Decoder will not work on all devices. If Morse Decoder doesn’t work on your device you can uninstall Morse Decoder within 15 Minutes for a full refund (This is the time frame given by Google and I am not able to change it). If the 15 minutes passed and you are not happy with Morse Decoder email me as soon as possible at firstname.lastname@example.org. Please include your name and the model of your phone in the email. I will then refund you the money as fast as possible. It is important that you include the model of your device. I will try to find the cause for the malfunction or include your phone model in a list of “not working” devices.
No mobile reception is required, you simply need a clear line of sight to whomever you would like to communicate with. Sending and receiving Morse messages is of course free of any charge.
Communicate with neighbors across the street. Use it for distant communication in the outdoors where you have no reception. Drop optical flash signals in an emergency situation or simply have fun.
The app has been tested successfully on Samsung Galaxy S2, Galaxy Ace and HTC Desire. Camera behavior may be device dependent. Please let us know, if the app does not perform as expected on your device.
The full version offers an unlimited auto-detection of signals, customizing settings, an SOS-mode, a message history and is ad-free.
