Or you can record "real" noise off the air and mix it in desired ratio with signal. And it can do FFT analyses, measure RMS power, generate interfering tones, etc. It lives up to its name! http://www.syntrillium.com I have no connection with Syntrillium - just a satisfied customer. 73, Stewart KK7KA ----- Original Message ----- From: "Holger 'Geri', DK8KW" To: Sent: Wednesday, December 20, 2000 12:15 PM Subject: LF: RE: PSK experiments > Andy, > > > >Does anyone have a programme to repeatedly play .WAV files in a > >continuous loop ?
