Hi,

I have a softrock kit here waiting to be assembled. Meanwhile I have started playing with the SDR software. Since I run Linux to the exclusion of M$ Window$ I have started working with Quisk. Today I finally got to the point where I have audio from my Kenwood (no I & Q) producing a spectrum display, detecting the CW signals, and presenting them to my ears. That is big step and had to sort out a lot of stuff. At the moment the waterfall display is all solid black. That will be another configuration step or peripheral software acquisition.

I expect the next step will be finding the keys to the waterfall display in the mountain of documentation. The results I have today are encouraging and I'll be using what I have so far on the air. I have no time some days and only a limited time on days when I can break out the "manual" but I expect to get it all working.

I intend to hook up the SDR to some of my regens and the WWII receivers that are wide as a barn door. And oh yes... to my SoftRock kit receiver when it is completed.

73,

Bill KU8H

Does anyone have the applications disc for the Extigy?

I have obtained a Exitgy for use with my Softrock ensemble and GSDR. But cannot get it to work as I need the application loaded before I can update the drivers from Creatives web site.

I have complete a 40/30/20 meter version of the Ensemble RxTx. ?It is working nicely as a Receiver on my Dell desktop via sound card. ?I have two issues to resolve. ?One is to get USB sound doogle so I can move the Rx headphones and TX microphone off the internal card. ?I believe they are in conflict now because I only have the one card.

Your display image reminds me what I got when there is audio feedback through the sound mixer.? You must have the line input silenced in the volume control.? Other mixer combinations may cause this also, for example having the mono or stereo mixers selected as input in the recording control instead of the line input.

Did you listen to the Ensemble II line out directly with speakers or some other line input audio device plugged into the Ensemble II (i.e., not using the computer at all once you set the LO frequency)? If so, what did you hear?
If you do not have a strong local AM BC stn, maybe one of the WWV frequencies will provide a strong AM signal for you to listen to.
BTW, your last screenshot post showed up fine in the Groups post.

What you see on the HDSDR display is what is coming from the soundcard USB output and then decoded by the software. You will get some kind of HDSDR display even if the rx line output is not connected to the soundcard at all (or is unpowered which will effectively disconnect the rx, as you showed in one of your screenshots). The rx might still be working fine. I think you can determine if the rx is working by setting the LO with CFGSR and listening to the rx output directly, not using the soundcard and software at all.

Sorry, what I meant was that tuning has no reception - there is nothing on the display to see but the picture displayed earlier - the LO and the TUNE themselves work fine.

No capability to tune - just the same display all the time

Re. my last post: it is only the Local Osc. freq that matters for listening on the rx line output (the TUNE freq in HDSDR has no effect with this test).

It is probably better anyway to use CFGSR to set the local osc freq to eliminate any problem with HDSDR. With CFGSR, you use the TUNE tab to set the LO freq. Sorry if this is confusing.

Perhaps we can rule out a problem with the soundcard and software decoding. If you use HDSDR to tune the LO and also the TUNE to a strong local AM broadcast station freq. with an antenna connected, then the audio should appear on the Ensemble II line output. I plugged a cheap computer amplified speaker into the rx and could hear the AM stn's audio, faintly but clearly on both the left and the right speaker. If you don't hear the AM station but hear the hash shown on your screenshot, this would seem to indicate a problem with the rx.

Hi Steve,
Other than the site listed in your post is there a Yahoo Group or forum on your project?
I'm interested in the next generation SRD and I have a? homebrew all band (hf-6) transceiver using PowerSDR.
I can't help with the code but would be willing to modify my existing radio as a test bed and have a fair amount
of test equiptment.

No, I get a horrible display with no signals at all when all is connected. See attached

without 12v I have a (reasonably) flat line @ 48khz - with the spike at the LO frequency
My internal card does 192/24
My external card does 96/24

Input : Softrock Si570

Input channel mode for RX: I/Q
Output channel mode for RX: AF to both channels

Swap I and Q is checked (I swapped the jumpers during build as recommended)

There is no guarantee that your sound systems will work higher than 48K without some configuration in their panels. Sometimes this can be tricky, so leave it at 48K for now.
So, do you now see signals when you connect a good antenna?
Assuming you have checked the basic sound mixer controls for correct input selection and gain.

I see all the screen shots in my email client (Apple Mail). I very rarely go to the web group page

I have a softrock ensemble Rxtx 30/20/17 that works well, and I have built the 30 meter filter for it. ?The Rxtx was built for me by Tony himself. ?But I just bought a new laptop with a weird sound card, and I'm doing pretty exclusively straight key work these days, so I'm ready to sell the softrock. ?$100
