Re: [Flexradio] wav file recording
If you are just playing the file back with an audio program that would play back music and such, you are getting what you should. Try playing it back with PowerSDR! What is recorded is the raw output from the receiver which is normally tuned 11 KHz off from the center frequency and then mathematically converted as you do the tuning. The 11 KHz shift is sometimes referred to as the IF frequency but its not quite that, more there to get any major spurs from 60Hz pickup off the normal spectrum screen. 73 - Mike WA8BXN ---Original Message--- From: Bill Nagle Date: 03/08/06 12:56:42 To: FlexRadio@flex-radio.biz Subject: [Flexradio] wav file recording When recording an AM signal on the sdr wave recorder, it plays back through the speakers properly but the transmitted playback sounds like it is off frequency by 11 kc or so. All you hear are the edges of the recorded voice and what sounds like frequencies on one side of it. Anyone else hear this in previews 15 and svn 16 ?
