[Flexradio] Edirol FA-66 drivers with Windows 2000
Is it possible to use the Edirol FA-66 soundcard with the Windows 2000 operating system? Will the Windows XP drivers work with Windows 2000?

I would speculate that since this sort of function is very popular for other uses (e.g. the music biz), folks are figuring you could buy some software to implement it (or find freeware), and then pipe the audio output to the PowerSDR input using VAC or something similar. For audio processing this is a MUCH more appealing model, IF the needed processing is available somewhere else. It keeps PowerSDR less cluttered. I'd rather the PowerSDR developers spend their time on radio specific features (like calibration and RF performance related things.. noise blankers, etc) rather than trying to build ever better audio equalizers, multiband compressors, or gods forbid, flangers, phasers, fuzzboxes, wah pedal emulators, reverb, etc. I don't know the specifics of what's available, but I have several friends working with fairly sophisticated recording studios and a LOT of signal processing in software (albeit most on Macs).

[Flexradio] w9ol rtty frequencies questions relating to WinWarbler
Ok, what I did was make up a zip file to show better than what I can explain. www.qsl.net/w9ol/w9ol.zip PowerSDR, Commander, and the upper right corner of WW all agree that the frequency is 14.087.82. Both xmit and receive. as I do NOT have split enabled in either Commander or PowerSDR. The anomaly is in the frequency displayed just above the mark/space lines in the tuning panel. They show a frequency of approx 14085.5++ (just interpolating) Which would be close to the standard 2210 normal optimal offset when operating in AFSK LSB xcvr mode. You may notice that Commander is indicating RTTY mode and PowerSDR is indicating DIGL mode. As both Commander and PowerSDR are in aggreement, as is WW in the Xcvr Freq. panel, my question is Remember I'm both synaptically and mathamatically challenged... HOW DO I, or even, CAN I make some adjustment so that the frequency indicated above the tuning panel is in agreement with all the other frequency displays. And of course, keeping the mark/space and signal curve somewhere close to the middle of the display for quick mark/space selection.(without having to add 2.210) (I rarely use AFC) As I used to only run fsk, I was used to looking at a cluster spot, find nothing, and then tune off 2.2 to find the station. But with a mouse and frequency display, my brain will have to do the mathand I haven't had a balanced check book in decades! this email also cc to Flex reflector to prove that WW/PowerSDR works quite nicely together. - You May be a CheeseHead if: Your sexy lingerie is tube socks and a flannel nightie - Bill H. in Chicagoland webcams at http://76.16.160.118:8080/ weather at http://hhweather.webhop.org ___ 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 Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
[Flexradio] Audio Punch
I have had my SDR-1000 for about 6 months now and I am very happy with it for the most part. After all is said and done the only criticism that I really have of the rig is the performance of the Compressor. What is this function actually? I have tried all versions of the Power SDR software and I just can't seem to get the compression performance that I am used to with my conventional transceivers. If I increase the level of compression to where I approach the level of average power that I am used to, the audio is not clear but muffled. The unprocessed audio with the SDR has been exceptional but the only way I can get the rig to approach the punch and talk power of my other rigs is to use my Ten-Tec 234 speech processor with the SDR. Using the external unit my audio is indistinguishable from a FT-1000D or TS-870 both using 10db of compression. I just cannot duplicate this with the software. I wonder if the guys at Flex realize that the processing is lacking? If not it may never improve. If so I'll wait patiently for an improvement.

Re: [Flexradio] Microphone for FLEX-5000
For what it's worth, I use a Heil PR-40 with my SDR-1000 (with Delta 44 soundcard). The mic connects directly to the SDR mic input (no external preamp needed), and I set the console's Mic Gain to 50, plus I add some mid and high frequency boost with the equalizer. That's all there is to it for the PR-40, and I get excellent audio reviews. 73, - Jeff, K6JCA -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Ray Andrews Sent: Wednesday, May 30, 2007 12:21 PM To: FlexRadio@flex-radio.biz Subject: Re: [Flexradio] Microphone for FLEX-5000 Alan, I am using a Heil ProSet Plus with my SDR-1000.

Re: [Flexradio] Microphone for FLEX-5000
We recommend any of the Pro series microphones offered by Heil. You will need a XLR to TRS [1/4 inch Stereo plug] cable-available at Radio Shack or just about any ProAudio store. You then can use the Balanced input on the rear of the 5000. We use the PR-40 mic in our labs. John P.

(that is, if you do an FFT of a signal that's actually at 20 kHz, it might show up in the bin for 20,002 Hz or 19,998 Hz. Typical specs are 30 or 50 ppm for the XO on a 1394b PHY chip (like the TSB81BA3). A bigger issue might be that the internal PLL in most PHY chips tries to track the clock of the incoming 1394 data. Too bad it wasn't locked to the stable oscillator...

Re: [Flexradio] Interesting Noise
That is how I first noticed it. It crawls in and out of the passband. For the most part I can remove it by clicking on the Spur Reduction button. It is only a minor nuisance when the radio is cold. It is rare to see it when the radio has warmed up. I think it is important that we discuss these issues without trying to blame Flex for anything. They have been responsive to just about everything within reason and have extended our warranties by a year which is something they didn't have to do. I'm very happy with my radio, the service and support as well as the help from folks on the reflector. I'm sure that a lot of us would like to see if Flex provides a solution. Then it would be up to you to decide if you want to go through the trouble of implementing it. Like I said, I ain't touching the innards of this radio, no matter what!

I refer to it as a crawling hump. It happens with and without the coaxial cable attached to the radio. The Spur Reduction button seems to manipulate it enough to keep it out of the receive filter bandwith. Because it can be manipulated as such, I thought it may have to do with the radio's DDS.

Re: [Flexradio] NR
The range of the controls (inside) have been changed, especially in the Block LMS case, in order to provide finer grained control and increase stability. In the setup->dsp LMS block, if block LMS is checked, INCREASE THE GAIN until you are happier. Yet, you may not get to the happy state right now. I really don't have time to concentrate on making these perfect in the SDR-X branch yet, so these controls are still under construction while the Flex 5000 work is rushing to completion. They will be revisited to insure the controls perform as well as 1.8.0 where IMO, this was the best NR and ANF around.

I'm sure there are many of us here, who like me, are quite happy to try out beta code but are not quite ready to step into the pool of SDR-X alpha code yet :-) 73 to all Trevor G0KTN ___ 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 Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/
