Soundcard and Audio Processing Software
Latest Updated Version .EXE and source code with I/Q input and selectable sampling rate
UWBCNMON.ZIP - Complete installation archive and VB runtime libraries
UWBCNMON.EXE - Stand Alone programme
Beacon Monitoring , Signal detection and carrier tracking, S/N
measurement and logging
UWBCNMONIQ.EXE - New Improved version
Now accepts I/Q stereo input from a quadrature downdonverter (SDR front end) with sideband switching.
It can cope with multiple soundcards, allows FFT window type to be selected and the sampling rate has been increased to 11025Hz to overcome the errors in the 8000Hz rate on many modern soundcards.
A silly programming bug in the FFT routine has also been repaired
The VB6 distribution archive for the programme is contained in the .ZIP file
which has all the VB run libraries and
setup for most of the other .EXE files in this archive.
The .EXE version can be used on its own if you already have VB installed
A description of the software can be found in UWBCNMON.PDF
VB6 Source code for both earlier and later versions.
to cope with those frequency calibration issues.

Signal measurement using the soundcard,
uses include noise figure measurements with calibrated noise head, sun and
moon noise, cold sky/ground etc. S/N measuremetns.
Adjustable interval and averaging times.
VB6 Source code can be found in SignalLevel.zip
Needs VB run-libraries
(download UWBCNMON.ZIP if not already installed)
WAVDSP.ZIP
A number of stand-alone utilities for analysing .WAV files, upconverting and combining several into one wide band stereo I/Q file. Utilites also allow .wav files to be generated with various modulation formats, such as BPSK31, FSK, parallel tones and chirps. These have been written over the last few years for my own interest and for particular one-off tasks.
