It was used by the German military during World War II to send messages encrypted by ENIGMA machines. Today it is used by amateur (ham) radio operators around the world to send messages to each other via shortwave radio.
Feld Hellschreiber literally means "bright field recorder". Hellschreiber is sometimes referred to as simply Hell.
Feld Hellschreiber lets you decode and transmit Feld Hell messages. Decoded text is continuously scrolled across the top of the display. You can type in text to transmit, or press a button to easily send canned text messages, such as CQ calls. Sound is picked up from your radio's speaker via the internal mic in your device, and transmitted audio comes out the speaker - you can also connect a patch cable to your radio's mic input via the headphone jack on your device to transmit the audio, if you wish.
The slider control adjusts the display contrast, and the indicator to the right shows the volume. Adjust the slider for the best display.
To transmit text, touch on the text entry field, and start typing. Each character will be sent when possible. When sent, it will be taken off the left end of this field, and displayed on the right end of the transmitted text field, to the left of the entry field, in a scrolling fashion.
Canned text buttons are also available, touch one to send the text stored for that button. To edit a button, touch the Setup button, and then select the button you wish to edit. You can edit the name of the button, as well as the text.
To decode transmissions, you just need to run the app, and set it near the radio's speaker or headphones, and watch the decoded text appear. It's that easy!
The developer is awesome. This is just another great app. Thanks!!!
This app just works. It is very easy to send and receive Feld Hell. I only wish there was more Feld Hell to be had on the bands. I have been using this app with my portable station. There is a long list of customizable macros that make using this app very easy.
Awesome! Sends and receives flawlessly. A compact package that does everything you want it to. Thanks!
Works, but audio is played through the phone speaker not the music speaker. Only useful with some sort of headphone setup.
Use this nifty package with iPhone 6 and a homebrew cable going to my KX3 radio. Works very well as a super small digital field station. Easy to setup the macros for typical QSO. Highly recommend. de K5YR
