About this app

No ads, nags, or in-app purchases. No internet connection required. Fully functional offline DTMF generator app.

Official DTMF pad of RFinder Android Radio http://androiddmr.com

Version 1.1.18 includes support for encoding CTCSS tones 67.0 Hz to 254.1 Hz. Tap CTCSS button to turn CTCSS on/off. Tap again to loop CTCSS in the background. Long click to select CTCSS frequency. CTCSS volume adjustment is included for noisy environments.

This app will give you a 16 tone DTMF (Dual-tone multi-frequency) keypad plus a 1750Hz tone burst button for use with European repeaters, and the ability to generate custom DTMF sequences as well as set the duration and tone/silence ratio. Additionally, 52 CTCSS tones are included.

Included are the characters 1234567890*#, the menu tones ABCD, plus a 1750Hz button for European repeaters. You may enter a custom sequence via the keypad, soft keyboard, or speech if your device already has speech-to-text capability.

To clear the DTMF sequence, tap and hold the DTMF button. Use the Mute button to silence the keypad during programming. You may use non-DTMF characters as pauses in the string.

This app will work in both portrait and landscape modes. To manually set portrait or landscape, hold the Mute button to override the sensor orientation. Restarting the app returns it to sensor orientation.

This is basically a touch tone telephone keypad, which may be of interest to amateur ham radio repeater operators, phreakers, preppers, and survivalists. If your radio or microphone does not have DTMF or CTCSS/PL tones, then you can use this app instead.
