Yes, unexpected unintended results. :-) Guess the post-processed audio, being at baseband, confuses the radio. -not sure of the terminology-
I did an Image Calibration (I've seen it recommended for a number of things). The problem went away. I don't see the mirrored spectrum after playing the post-processed audio. I still can't listen to it, but at least NO unexpected results afterwards. I know the EEPROM is updated after an Image Calibration but I don't know what all is saved (I am curious though). Magic! Thanks for the replies. I'm now better informed.

Playing post-processed audio into the radio expecting I/Q data will have all sorts of unintended results. If you want to record off the air signals just to listen to, the use the WAVE form and record, by pressing the record button, (Receive) pre-processed audio. You play it back by selecting it file you just recorded by adding it to the playlist and clicking on the PLAY button. Use the loop option to continuously loop the recording. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bill K7UOP Sent: Friday, February 25, 2011 7:27 PM To: 'pierce day' Cc: [email protected] Subject: Re: [FlexEdge] Wave Play problem PSDR v2.0.19 RC1 Thanks for the reply Pierce. I was recording another stations audio as a test and then tried to play it back. I didn't want to transmit so I did not turn the MOX button on. I just wanted to listen to it locally. The problem is... that after I play any post-processed audio, it creates havoc with the Panadapter display. Afterwards the display is centered 9 KHz below my tuned freq and all received signals are mirrored symmetrically on both sides of center. I take it you are not having any problem with your setup using v2.0.19 RC1 and it works ok as you describe(?). I am wondering, is anyone else having this problem with the new beta release of PSDR???? I captured jpegs but I don't know if this reflector allows attachments. I'll hold them unless someone asks to see them. 73, Bill - K7UOP -----Original Message----- From: pierce day [mailto:[email protected]] Sent: Friday, February 25, 2011 3:45 PM To: Bill K7UOP Subject: Re: [FlexEdge] Wave Play problem PSDR v2.0.19 RC1 Bill: If you just want a quick record/play, click the MOX, click the white RECORD button, then speak. To playback, click MOX, then click the PLAYBACK arrow. If you don't want it to go over the air, turn drive to zero.
