What is presented here , is what our members use to assist in the hobby.

Great tools that use the Soundcard and the scanner will provide you with not only major savings in $$ in hardware, but ease of use.

VOX RECORDER

Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists. If you are one of them, you already know how much time has to be spent when monitoring a new frequency: the traffic on the new channel is very sparse and communications are short, with long pauses between each one. With Vox Recorder you can compress a whole day's worth of monitoring onto a single .wav file. You can leave the computer on and connected to a scanner at home while you are at the office or doing something else; later, you can listen the messages caught by your radio how many times you want. In this way you can quickly monitor suspicious channels and have all the "action" into a single audio file.

WINTONE

WinTone was designed to be able to decode virtually any set of tones, regardless of their frequency. And since there are so many different Tonesets (DTMF, CCIR, ZVEI, EIA, EEA, etc.) we decided to make WinTone modular. If you need to be able to decode a different standard, simply copy that DLL into the WinTone directory and you instantly have access to tone decoding.. That simple.

Tone Squelch Selection The other type of ToneSet is a Tone Squelch set. These tones are normally constant in the background of any transmission, and are usually sub-audible. An example of this type is CTCSS. They are used mostly for multi-user frequencies when you only want to hear one particular conversation, but do not want to hear anyone else. The tones are used to "Break Squelch". These tones are selected in the same way as active tones, by selecting the available modules from the pull down box. Only one of these tonesets may be active at one time, but they may be selected along with an active ToneSet.

VOICE INVERTER

Invert is a simple speech inversion decoder.( Currently Decoding The Espanola Police ) The usage is very simple: "Start" starts the speech inverter, "Stop" stops it. The inversion point is adjusted using the slider control. Be aware that the output is always one buffer behind the input so that the slider control has a effect that is delayed by about half a second.

DOS/WIN CTCSS DTMF DECODER

The program samples the input, performs an FFT, and graphs the output. It also decodes and generates DTMF numbers and the sub-audible CTCSS tones. INI file and command line options provide the user with the ability to select linear/log frequency and amplitude scales as well as sampling rates, length of the FFT, DTMF generating speed, threshold DTMF and CTCSS level etc. Graphics is done using the VGA 640x480x16 video mode, so a VGA compatible card is required. The program will only run on computers with an 80386 or above processor. A coprocessor is recommended, but not required.
