Morse Decoder decodes Morse code characters through the built-in microphone of your Android device.

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.

For any question please visit our new forum at http://www.wolphi.com/forum/

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 info@wolphi.com. 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.

A tool designed by a Ham (KD7UIY), used to figure out your QTH, in Amateur Radio speak. Specifically geared towards the Mobile radio operator. This comes out of the need to figure out which county a person is in during many state QSO parties. Includes a simple log, and can now be able to even work without the internet at all (With in-app purchase)! Free version includes ads, and requires an internet connection to provide county, country, etc, but it will provide latitude, longitude, and grid square without internet access.

Works with either phones, or tablets. Tablet version makes it easier to manipulate data, and do logging, even having the ability to see current data while logging on screen (See screen shots). ADIF files can be exported, including all information collected (Upgrade required). The feature list is improving constantly, now the ability to edit and delete log entries is included, along with a database of all LOTW listed call signs. See a map of where you've made QSOs that are logged. Check the DXCC of the callsign you are considering logging. More coming soon!

The tool is US centric right now, but an effort is being undertaken right now to expand the list, particularly in offline operations. Already the local translation is used for States and Counties, and will likely be used for Countries soon. I'm working on improving the translations across the board, in fact, to simply work everywhere. If there's a particular location you'd like to see, or would just like to help improve this app, please take the survey at https://docs.google.com/forms/d/1AfrKLXJwt9l1e-1Rew7G5WLyorcd_kLWyRmt82rw994/viewform

Reasons for each permission required:
ACCESS_FINE_LOCATION- This app uses GPS to determine where you are, and requires this permission to get that information
INTERNET- Used to query web APIs about your exact location.
ACCESS_WIFI_STATE- Used to make sure we don't try to contact someone if you don't have a network connection
WRITE_EXTERNAL_STORAGE- Used for Google Maps to determine your location if you don't have one
VIBRATE- Used to notify user of some errors
READ_PHONE_STATE- This is used to ensure that each user has a unique token, only used for those who purchase in app products.
BILLING- Used to purchase in app products, such as US Counties Map.

This app is for use by licensed radio amateurs to send APRS position beacons and messages from an Android phone or tablet over a 3G or Wi-Fi connection to the worldwide APRS internet system. It can also be use to link by Bluetooth to the Cross Country Wireless APRS TNC Digi Tracker with the Bluetooth option.
The app is very simple to set up just needing an amateur radio callsign and the APRS passcode for that callsign (available on request from Cross Country Wireless).
Menu options include GPS position information including WGS84 locations for worldwide use and.OSGB locations for UK users. Another menu option also opens an OpenStreetMap based on the GPS fix.
The app can be used on any Android phone or tablet with GPS (and Bluetooth for use with a DigiTracker). If your Android tablet does not have GPS then the app will not work.
Note...the GPS on some Samsung phones doesn't work with this app. As a result the app is now provided free of charge for amateur radio experimentation.
