SpectraVue

A Windows based Spectral Analysis/Receiver Program primarily used with the SDR-IQ,  SDR-14 , SDR-IP, NetSDR,  RF capturing hardware(http://www.rfspace.com) but can also be used to analyze soundcard and wave file inputs.

Program Features

• Input Data from Wavefile, SoundCard, or  SDR-IQ or SDR-14 USB Hardware, SDR-IP, NetSDR Ethernet SDR Hardware
• Spectral Display of Data in Frequency Power in a variety of formats
• Save Data to RIFF wav format files for archive or later analysis.
• Demodulate signals in real time to soundcard or to RIFF wav file
• Two independent demodulation channels are possible
• Control RFSpace SDR-14, SDR-IQ, SDR-IP, NetSDR hardware.
• Timed Auto capture for unattended operation.
• RIFF wav files have special embedded timestamp and sampling information.
• FFT configurations for size(2048 to 2M pt.) and amplitude(.2 to 15dB/Div)
• External Radio modes allow extending SDR frequency range using IF signal inputs
• Use external FFT compensation files for flattening the filter responses
• Configurable Demodulator Band Pass filter responses
• Save Waterfall to BMP file with full FFT resolution

• ICOM R8500 , AOR R5000 and other radios as Panadapter using standard PC serial Port

WaveVue

WaveVue is a utility to allow viewing and saving off segments of a wave file.  There is no help file but it is pretty self explainatory.  WaveVue Download Page

Here is a capture of the AO40 passband showing an unusual interfering signal tuning across the middle beacon.  The discretesteps would indicate a synthesized source.  Also the signal gets modulated by the beacon when it is close to it.  This was captured by AA4RC's station.  This 3:40 minute file(~40MBytes!) can be downloaded from http://www.rfspace.com/noise.zip and played back using the SpectraVue demo version.

The following is an experimental version that couples SpectraVue's soundcard output into the DRM(Digital Radio Mondiale   http://www.drm.org  ) Receiver software "Dream".  The DRM signal is a 10KHz wide digitally modulated that has a very rectangular shape as seen in the spectral view.  Compare it to the normal AM shortwave signal to the right of it in the spectrum.  Here is a recording of the audio as received from a DRM station in Canada.  drmaudio.zip  (~900K wave file)  Note this is not a good example of the audio quality since it is recorded at only 8KHz.
