During the last few years I have received many enquiries regarding soundcard software for decoding OSCAR-11 signals, and from time to time there has been some discussion on AMSAT-BB about the need for this software.
I am pleased to say that a suitable Windows program for displaying and capturing OSCAR-11 data is now available. This is MIXW2, a general purpose Amateur Radio data communication program written by Nick Fedoseev UT2UZ.
You can download the the program from www.mixw.net or do a google search for MIXW. You need the latest version 2.07.
The OSCAR-11 feature is un-documented at present in MIXW. I have therefore prepared some instructions to help users. I have also included a filter program which enables the data captured by MIXW to be used with the ASCII telemetry & WOD programs on this website. Also included are sample files of data.
I have found that this program works very well on OSCAR-11, and gives excellent results comparable to a hardware decoder.
