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 email@example.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 waterfall shows the frequency spectrum of 100Hz to 2500Hz. Just slide the waterfall slide on a RTTY carrier frequency and DroidRTTY will decode the signal.
In transmitting mode characters can be entered trough the keyboard. 9 Macros are also available to store standard texts like “name and qth” and “station info”
DroidRTTY also now includes a logbook. Callsign, Name RST etc can be easily tranfered into the lookbook from the receiving screen.
The logbook also includes ADIF export and import to transfer your logbook data to a PC based logging software.
Version 1.10 also includes 50 baud / 450Hz shift to receive the German Weather Service (Deutscher Wetterdienst)
DroidPSK is able to decode a BPSK31 or BPSK63 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.
In transmitting mode characters can be entered trough the keyboard. 20 Macros are also available to store standard texts like "name and qth" and "station info"
Starting V2.0 DroidPSK now also includes a logbook. Callsign, Name RST etc can be easily transferred into the lookbook from the receiving screen. The logbook also includes ADIF export and import to transfer your logbook data to a PC based logging software.
If you like to see more information you can take a look at the manual at: http://www.wolphi.com/ham-radio-apps/droidpsk/manual/
The suggested frequencies for PSK on the Amateur Radio bands are:
- 160m 1838.15 MHz

If you experience any problems or have any suggestions please let me know at firstname.lastname@example.org. I would like to hear your feedback.
If you are a ham radio (amateur radio) operator or just want to learn morse code.
With a lot of settings it is very comfortable to adjust Morse Trainer to your current level.
The following settings are available:
- Frequency (200 - 2200Hz)
- Waveform (sine / triangle)
- Fading (to reduce click at the end of a dot or dash)
- Speed (2Wpm - 52Wpm)
- Farnsworth speed
- Spacing (spacing between dots or dashes)
- Dot-Dash Ratio (length ratio of dashes compared to dots)
- Letter Spacing (Space between letters)
- Word Spacing (Space between words)
Five different learning modes are available in Morse Trainer
- Random groups of X mode: Morse Trainer will play groups of X randomly selected letter, numbers or special characters. X can be an amount between 1-9. Those characters can be individually selected. If you want to learn just "s","i" and "e" just select the 3 letters and Morse Trainer will create groups of X with those 3 letters.
The characters can also be chosen from 20 lessons of the Koch method.
- Real ham radio callsign mode: Morse Trainer will randomly play real amateur radio callsign from a database of 5000 callsigns which appeared in Contests over the last couple of years.
- QSO text mode: Morse Trainer will play randomly play QSO text. The database consists of 300 different qso texts.
- Most common English words mode: Morse Trainer will play randomly the 500 most used English words.
- Own text mode: Enter your own text and Morse Trainer will play it over and over again.
- Ebook mode: Text files can be loaded from SD card
Morse Trainer is priced less than the cost of a fancy coffee and it is a great app to learn and improve you CW speed away from your amateur radio station or your PC.
DX Cluster's focus is on alarms and real time spots. The app runs in the background as a service and alarms you with a ringtone of your choice when a callsign or prefix appears in the DX Cluster.
The key features of DX Cluster are:
- Real time spots: Connect to one of the 60 AR-Clusters in the database and get real time spots.
- Filtering: A country filter can be set to filter out countries of the spotter or spot. If you just want to receive spots originated from North America enter K,VE and choose spotter. If you just want to see spots from Germany, Netherland and England, choose DX and enter DL,PA,G.
- Alarms: DX Cluster will alarm you by a ringtone of your choice if a callsign or a prefix appears in the DX Cluster. For example enter ZL8 in the alarm field and as soon as a spot with the prefix ZL8 appears on the cluster the DX Cluster will alarm you. Multiple callsign or prefix entries are possible.
This app is intended to use by ham radio (amateur radio) operators only. You need a ham radio callsign to log into the DX cluster!

*** Now includes band limits for All Amateur Licenses ***
*** Calculators for Yagi, Dipole, J-pole, and Vertical antennas ***
*** Callsign Lookup is now included!!! ***
Callsign database is pulled from FCC website and updated daily! Callsign lookup works for U.S. callsigns ONLY.
Results include address, current and previous license updates, date of any updates, type and class of license, and even includes a link to the FCC database for even more details. Address can be mapped on Google Maps by tapping on the address.
The contact log allows you to store information about a completed contact including date, time started, time ended, frequency, mode, station, location, signal reports, and an area for general comments about the contact. A must for field day and general book keeping. Data and start time are filled in when starting the log to save time. End time can even be filled in automatically upon saving the log entry.
The contact log also comes with a handy search feature for quickly locating that one of a kind long distance contact you like to brag about. The search is focused on fields chosen by the user. If you want to search for a specific call sign select station as the search location and enter the call sign in the search box. Search keywords are CASE SENSITIVE meaning capital or lowercase letter DO matter.
A summary of the band limits for each class are included. Always refer to the official ARRL Band Plan when in doubt.
Some simple formulas and calculators are included for quick reference in the field and includes: Yagi, Dipole, J-Pole, Vertical antennas, and wavelength calculator.
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. More coming soon!
Currently, this tool is US centric, but there are plans to change that in the future. Specifically, operating outside of the US requires an internet connection.

EchoLink for Android provides access to the EchoLink network from your Android device. You can use this app to connect to the EchoLink system from almost anywhere, using either a WiFi or cellular (3G/4G) connection.
Es contacts via the sporadic E layer of the ionosphere are shown in red.
Sporadic E propagation on the 2m band is very rare and happens mostly during summer and at daylight time.
The development of this application is described in detail in the August 2012 issue of the German FUNKAMATEUR magazine.
This app just displays Gabriel Sampol´s EA6VQ web page at http://www.dxmaps.com/spots/map.php without any modification like any web browser with the appropriate bookmark. You can follow the links on this web page in the same way as with other browsers.
With this App you can create the coverage map for HPF, MUF and FOT based on the location QTH of your radio station TX defined by latitude and longitude and minimum radiation angle.
Coverage maps are produced by calculating a huge amount of point-to-point circuits from the transmitter to a world wide receiver grid of 88 x 64, This are 5632 point-to-point calculations of the HF path for 24 hour of the day. A SAMSUNG Galaxy II will need less than 1 minute to compute the maps, valid for the selected month.
The used algorithm are based on the HFMUFES FORTRAN library as used by HFMUFESW, IONCAP or VOACAP but ported to JAVA classes. The last computation is retained and a new computation will be done at changed entry values only. Ionospheric data are inside the JAVA classes for all months and sun spot number 10, 30, 60, 90, 120 and 150
During map view you can switch between HPF, MUF, FOT and each hour of the day (UTC). The display will be on as long the map view is shown. There are a bunch of different color palettes that can be selected. The current selection is retained at App exit, so you must go back to the main menu to have the map saved. Later when you touch draw the map button again the the last version is shown. To compute again, modify an entry value, month or ssn.
Gray-line (dawn zone) and the position of the sun is adjusted for each hour.
At each touch in the right area the day time (UTC) is increased, in the left screen area UTC is decreased.
Watch the touch area functions displayed during the computation.
At the Highest Possible Frequency HPF, communication can be supported on 10% of the days (3 days) in the month. At the Frequency of Optimum Traffic FOT, 90% of the days (27 days) in the month and at the Median Maximum Usable Frequency MUF, 50% of the days (15 days) in the month.
