SpectraScope is a simple Windows interface program allowing your computer to view up to two audio waveforms in either the time or frequency domain. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer. The useful frequency of operation is 20 to 10,000 Hz in the time domain and 20 to 20,000 Hz in the frequency domain. The program uses the computer sound card to capture the audio input.

SpectraScope Features:

1. Simultaneous two channel operation
2.Separate gain and offset controls for each channel
3.Time or frequency domain measurements
4.Channel Add mode
5.Channel XY mode (allows display of Lissajous patterns)
6.Multiple triggering options
7.Single sweep capability
8.Display hold
9.Dual vertical markers for waveform time measurements
10.File save of the form or graphic screen
11.Trace and background color selections
12.All menu selections and most of control settings are saved in a Configuration file.

Packet Terminal Interface Program Features
•Simple Windows based TNC interface program
•Designed for ARES operation
◦Simple operator interface to connect and perform communication functions
◦Control operator programs screens before operations
•Both receive and transmit screens
◦Operation via single or dual screen modes
•Transmit control via TNC commands
•Text file transfers

Vox Recorder Features

The Vox Recorder program incorporates the following features:

·        Voice activated recording (.wav format).

·        Continued recording (hangtime) from 0.5 seconds to 5 seconds.

·        Playback of recorded audio.

·        File to file transfer of the audio with both voice activation and filter enabled.

·        Mono or stereo recording.

·        Supported sample rates of 11025 Hz, 22050 Hz, and 44100 Hz.

·        Input and output Sound Card selection

·        Timed (to the hour, minute, second, and AM/PM) recording.

·        Timeline display of the recorded or playback audio.

·        Bandpass filter (bandwidth/limits can be set by the operator) of recorded or playback audio.

·        Output volume control.

·        Help file support.

Click on the program in the list to download it onto your computer. Then run the .exe  program. After the files have been unzipped (to the directory of your choice), run the Setup.exe program. All programs are around 2 megabytes in size except for the instrument tuner which is about 900 kbytes. Programs that are now Windows 7/Vista compatible must have the previous versions de-inst alled (use the Start->Control Panel->Add/remove programs). The new inst aller will not remove the previous inst allation and programs may not execute properly if the previous version is not de-installed!
