ComTekk Tone Generator - ComTekk Software Tone generator for 2-way radio signaling. Use sound card to generate CTCSS, DTMF, tone remote, ANI and more. Synthesizer for simulation and testing of 2-way radio systems, repeaters, remote control, ANI, Paging and more

DTMF decoder - A very easy to use program to decode DTMF dial tones found on telephone lines with touch tone phones. The DTMF Decoder is also used for receiving data transmissions over the air in amateur radio frequency bands.

MT Hell - MT-Hell software for 16 bit Soundblaster cards. Sends seven parallel tones with careful dot shaping for minimum interference, and transmits a very nice sound by G3PPT

CW Decoder  ^pop - This program allows CW operators to copy CW code with a computer. The decoded CW is displayed as text or can generate a side tone. There is a spectrum display of the audio with a sliding cursor to select a particular audio for decoding. The program also allows for keying a transmitter from the keyboard with full CW break-in operation.

MorseGen v1.2 - MorseGen converts text into a WAVE file of Morse code. The Tone and Speed are adjustable and the WAVE file can be repeated at a pre-set interval allowing it to be used as a CW Ident for amateur radio applications which require it.

Morse Tone Encoder - Generates Morse tones using the Soundcard. A neat tool for sending out short sequences of Morse tones.

TCube - TCUBE is a combination of a Spectrum Analyzer and a Two Tone Generator, with optional quadrature outputs. It can be used for measuring the intermodulation behavior of an audio circuit, and as a general purpose tool

DTMF encoder - Generates dial tones using the Soundcard. A neat tool for sending out short sequences of DTMF tones.

Tone Keyer For Morse Code Programs - Key your transmitter from the tone output of a Morse Code generator program

FM Morse Code Keyer - A simple circuit which will generate a 700 Hz tone into any FM transceiver allowing an amateur to practice CW with another amateur on a 2 meter simplex frequency.

An Inexpensive PL Tone Encoder - If your local repeater has got you singing the PL tone blues, then read on. For less than $10, an inexpensive PL tone generator can be constructed that will bring new life into that old non-PL rig.
