I like the concept of your program. It looks just like what I’m trying to write. Sent from Windows Mail Hi,
this [ https://sourceforge.net/projects/automodrecog/ ] is my little effort about handling IQ files. The input IQ file is recorded with HDSDR, very nice piece of sw, that as a good recording scheduler. By the way the file provided can be played with it. I do also some tests with IQ file produced by R&S EM100 receiver. I wrote this [horrible] application for personal use and it's very raw IMO.... I'm interested on HF monitoring and the main goal is to find SSB emission along time, not quite simple task. In brief: - read params from input file - split it in smaller chunk and save FFT for each chunk - sum (maxhold) or avg (average) all the FFTs - find relevant ( over threshold) carrier and try to "pack" them to find "bandwidth" associated - build a report as .html page with a .png file that represent the result. The most difficult part is to estimate the best "threshold", and at the moment I'm almost stuck there.... and moreover RL reclaims my presence :-) ... my euro "cent" on the subject.
