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!

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 Ham Radio Tools you can:
-look up callsign information!
-find current GPS location information
-save each contact to a log database stored on the phone
-review and edit each log entry
-search for keywords in different fields of the log entry
-calculate a simple quarter and half wave antenna length
-calculate the wavelength of a frequency
*** 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.
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)
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.
The free version includes ads, and includes the latitude, longitude, and grid square with no internet access. It requires an internet connection to provide county, country, etc
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. Submit your logs to Logbook of the World and eQSL. LOTW includes putting the logged information from Ham Finder in to your contact, so you can travel from gridsquare to gridsquare and not have to do anything special to log your contacts! 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
Note: This app will NOT help you find the best ham in your area. Sorry.

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.
VHF DX spots, posted by radio amateurs to the worldwide DX cluster, are constantly monitored and analysed by the gooddx.net server. When a Sporadic E, TEP or Aurora opening is detected, the DXrobot will send targeted push messages ONLY to users in relevant countries (countries where the opening actually occurs). These users will then receive a notification message (and optionally an alarm sound or vibration) on their Android device. Tapping the notification icon will show a handy overview of all countries (prefixes) currently active. The overview is grouped by VHF band (2, 4 and 6 meters) and by propagation mode (Es/TEP and Au).
The colour of notification icon indicates the status:
- grey: connected to DXrobot, but no current band activity - this is the 'normal' state.
- yellow: lost connection to DXrobot - trying to reconnect every 5 mins
- red: Es, TEP or Aurora activity on any of the VHF bands
An additional yellow icon will appear when a newer version of EsSense is available - tapping it will bring you to the Play Store for easy updating to the latest version.
When an opening has occured, and you tap the screen then a new screen will open showing the latest Sporadic E or Aurora spots on the DXcluster. Wait 30 secs or tap the screen again to go back to the main screen.
When EsSense is running, and you want to switch to another app, then tap the HOME button. This will keep EsSense running in the background so that it keeps listening for incoming alerts. If you tap the BACK button instead, EsSense will close down completely and disconnect from the server - so you won't receive any further updates.
Tip: On some devices the Wifi will be automatically switched off when the device goes into sleep mode. The connection to the DXrobot server will then be lost and no alerts will be received. To prevent this you can install an app that keeps Wifi alive even when the device goes into sleep. Several free apps are available for this on the market (search for "keep wifi alive" or "keep wifi on")
The EsSense icons were made by my daughter Suze.
This is a beta test version and it is currently still free. However, in a future version this may change depending on the volume of push messages that are sent. I may then have to charge a small amount to cover the cost for 3rd party push messaging services.
If you have any suggestions for further improvement, please email me at firstname.lastname@example.org. Your feedback is appreciated!
