Hi Tom, Are you using the Delta 44 card? If so, try changing its DMA Buffer size to 512 samples. Note: you *cannot* access this third buffer (the other two being the SDR1K Audio buffer and DSP buffer) from the SDR1K Console Setup menues. Instead, you must launch the M-Audio Control Panel from your computer's Task Bar (on my computer this is the bar at the bottom of the screen, and the M-Audio Control Panel is a small icon on its right-hand side). You'll find this buffer under "Hardware Settings" in this control panel.
I'd had exactly the same problem on my computer, and this fixed it. Best of luck! - Jeff, K6JCA -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Tom Thompson Sent: Tuesday, June 27, 2006 5:33 PM To: Robert McGwier Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] audio pop Bob, I downloaded 1.6.3 svn 560 and the pop is gone with the dma buffer set to 2048, the audio buffer to 1024, and the dsp buffer to 2048 with the sampling rate at 96000. When I set the dsp buffer to anything smaller than 2048, the audio motorboats. However, if I set the audio buffer to 2048, the dsp buffer can be set all the way to 256 without motorboating. I just do not understand the relatioship between these buffers well enough to know if this is really a malfunction or not. On the X2 delay issue, I thought the delay was to enable one to key an external amplifier before the SDR put out any RF and then to turn the SDR off before the external amplifier was switched from the antenna, and the delay was in milliseconds. It appears that that is exactly what is happening when the SDR is keyed. When the SDR is unkeyed, the RF and X2 relay keying drop off together, but the tone during tune remains for the delay time. I set the X2 delay to one second so I could better tell what is happening. Under normal operating conditions this is not a problem. The only reason I mention it is maybe that is not the way you intended it to be. Thank you for all the effort on this. 73, Tom W0IVJ _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
