[Flexradio] Audio Levels from Sound Card
ZS6AVM Wrote: This is something which I've been meaning to ask for a long time now, and kinda keep forgetting to do so When running the Audio Test in the Test Menu, I find that one channel is louder than the other I wonder if this is a sound card issue, or if there is some way of equalising the audio levels in the left and right channels I've looked in the Delta 44 setup, and don't seem to see an obvious way that this can be done Perhaps left and right audio levels equalisation could be some how programmed in PowerSDR ?

Re: [Flexradio] Audio Levels from Sound Card
Dave, I am not sure about any adjustment, but there is an excellent display of the ADC-L dBFS and ADC-R dBFS values in the Rx Meter at the top right of the PowerSDR Console display. Check those levels and you will find that they are +/- 1db of each other. Perhaps the Audio Test is giving you a difference in level, but that the actual I and Q signals (ADC-L and ADC-R) are properly balanced.

Check the mixer settings on the Delta Control Panel and you may want to check your cables as well. It could be in your speakers too. Note that the ADC L and ADC R values measure the input.

[Flexradio] Linux SDR TeamSpeak questions
Hi, All, I sent this to the linux-dttsp list and then realized that not everyone who was present for the EXCELLENT TeamSpeak last night is necessarily subscribed to the linux-dttsp list. I apologize for the redundancy for those who are subscribed to both lists. For those who asked me about [1] Linux SDR-1000 hardware control and [2] BeBob [FreeBob] on the TeamSpeak session last night [great session, guys...Thanks!] I note the following: 1. My dttsp webpage has information on using HamLib to control the SDR-1000. I am listening to the SDR-1000 as I type this, using HamLib to set the frequency and Preamp and attenuator levels. It works fine and the steps to using it are detailed at: http://www.nitehawk.com/w3sz/dttspw3sz.htm , item 16. Exact URL is: http://www.nitehawk.com/w3sz/dttspw3sz.htm#16 I have not tried to control transmit yet with HamLib. I haven't played with Frank and Bob's code since Thanksgiving. At that time it was not functioning properly for me, and I never heard about any subsequent updates. So I have stayed with HamLib as it works nicely with no need for 'fiddling'. 2. Last October I got my Firebox working under Linux with the SDR-1000 and SDR-Shell, gbeppe, etc by using BeBob variant FreeBob. This was not a simple task due to the fact that Ubuntu uses its own versions of many Linux Packages, and these versions did not satisfy the dependencies of other packages needed to run FreeBob. As of last October there were inkings of a version of jack that would contain FreeBob capability out of the box. I haven't looked into this here since I have been busy with work, and don't know what if anything has transpired in this regard. So my somewhat arduous 'formula' may be very much out of date at this point. But it worked for me, and I am listening to the SDR-1000 using SDR-Shell via the Firebox as I type this. My info is again on my webpage at: http://www.nitehawk.com/w3sz/dttspw3sz.htm , item 15. Exact URL is: http://www.nitehawk.com/w3sz/dttspw3sz.htm#15 Hope that helps! 73, W3SZ Roger Rehr http://www.nitehawk.com/w3sz Roger Rehr W3SZ http://www.nitehawk.com/w3sz ___ 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/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
Re: [Flexradio] What does Vista Really Mean?

I would expect that the vast majority of current XP users won't upgrade on the same computer to Vista. Rather, they'll just happen to buy a new computer with Vista already installed on it, and given the gradual increase in performance over time, the relative demands of Vista on a new machine in 2007 will similar to the demands of XP on a new machine back in 2003. As to what kind of horsepower would be needed to run PowerSDR under Vista, compared to running it under XP, I have no idea. As the first few Vista machines come out, I suspect someone will try it and see...

Re: [Flexradio] Help with Power Amp Calibration
Just taking a guess here Doug, can your power supply provide 20 to 25 amps of current without voltage sag? Measure the voltage at the SDR-1000 terminals.
