SR-40 Software Install Instructions [My Ver.]
SR-40 Folks, The things I learned by doing the installation incorrectly may be of help to others. Especially those of us who are not software/hardware technicians and engineers. If your computer is

[ Got it -- Duh ] SR-40 Fatal Error
Not thinking about what was really supposed to happen... My mind isn't working -- as usual -- the install direcdtory/folder is not the temp directory/folder...[g] I checked the Program Files folder,

Re: SR-40 Software Install Fatal Error
Chuck, Have you intalled the Softrock files into the same directory as PowerSDR? The files that are Soft-Rock specific are supposed to be written over the ones that come with the Power SDR

SR-40 Software Install Fatal Error
The install of the PowerSDR v1.4.4 seems to be OK. I can select the installed shortcut, see the screen and manipulate the controls. When I run the PowerSDR.exe SoftRock 40 Editon, I see the loading

Re: Success on Linux
I updated to the latest wine from winehq.com and the window display issues went away. SDRadio is much easier for me to use than PowerSDR. It is just two files, runs right away, and has almost no

Re: Success on Linux
Do you mean DTTSP or SDRadio? SDradio would probably function equivalently on Linspire. They or the CodeWeavers / Crossover people might have a little better luck with the window edges and the

Filtering DDS spurs possible?
I have a question about DDS performance. I look forward to the day when DDS is not a bad word with regard to receiver LO performance. There has been much discussion in all the email lists that involve

Re: Success on Linux
What might be the success of using it with Linspire 5.0? I know many Linux users do not consider it "real" Linux but it works for me since I am not very geeky. I do not have my receiver yet so I have

Success on Linux
I finished my SoftRock-40 and it worked first time on Windows with SDRadio. Thanks! I tried installing jDttsp and its many pre-reqs (python-2.4, jack, GNU SDL-1.6) on FC3 but I couldn't find any

Re: DSP Image Rejection problem and some thoughts
Hi Eric, I/Q outputs from U6 should be better than +/- 20% of each other. If one of the control signals to U5 (pins 1, 4, 10 or 13) is missing then the balance would be out by 50%. Please check

Re: DSP Image Rejection problem and some thoughts
Double check the 4 signals controling U5. Also double check the component values and placement around U6.. You said you did that, but another check wouldn't hurt. c12 AND c13 of different values

Re: DSP Image Rejection problem and some thoughts
I'll give it a try. I put a scope on I and Q earlier in the day and discovered more than a small difference between the two. More like a 50% difference. That seems excessive, and might suggest

Re: DSP Image Rejection problem and some thoughts
Eric, There may be a small difference in the Softrock40 I and Q amplitude that is out of range of the DSP gain/phase adjustments. I would suggest opening your computer's Recording Control window and

Re: What liquid solder to buy?
Thanks Dave. It is pretty toxic stuff too, and dispensing with a toothpick is going to mean wiping the toothpick onto something once in awhile to keep the toothpick clean and prevent a big glob of

Re: What liquid solder to buy?
Wow, Art, you scared me for a moment. I once saw a brand new Heathkit HW-101 that a young new ham had assembled using the plastic type "liquid solder". It never did work. I've had limited success

What liquid solder to buy?
Hi All, I have been using liquid solder (paste) with great success. 5 years ago, I started out with a sample sent to me for free by a vendor. It was sent without an applicator, so using it on really

It works !
Completed assembly several days ago. Currently Using I2PHD's http://www.sdradio.org/ program which I had already installed on my PC for experimenting with the R2PRO. Was able to get at least 50dB

Re: DSP Image Rejection problem and some thoughts
Good, makes sense. The card is trying to read micro-volt signals, the ground used for power in a PC is horrible as far as noise is concerned. To make matters worse the power supply ground is
