After 3 long days of waiting for my softrock to arrive, it finally did! Now I won't be waiting at the mailbox to meet the mailman! Took me much longer than 3 hours to build, but I made some errors

Changing from "DirectSound" to "MME" also fixed the popping problem here. 73 de Tom NU8D ________________________________ From: softrock40@... [mailto:softrock40@...]

Hello all, I have started a frequently asked questions notice, and posted it to the Files Section. Please refer to this file when faced with a SoftRock startup problem. I will add topics to the list

Hi Chris, Not being able to null the image is usually associated with I and Q not being about the same amplitude and not being at around 90 degrees phase relationship to each other. This problem can

Hello Chris, My answers in line Hmm -- not sure the freq calibration will have any effect with the soft rock as that is used to calibrate the DDS reference osc, and there ain't one in a SoftRock

Hi Guys, I am working on getting this little receiver up and running but noticed a few things I wanted to ask of those more experienced. I connected my generator and set it to 7.040 Mhz at -60 dBm

Hi Bruce, That fixed it! The background would pop and shift levels even with no antenna or signal generator connected. Quite annoying when listening to a faint signal. Now that I got that taken

Looks good, Chuck. Mounting it vertical is a great idea. I think I'm going to do that with a Rock-Mite, too! Eric KE6US www.ke6us.com --- Chuck Carpenter <w5usj@...> wrote:

SR-40 Folks, Finished the mechanical assembly and posted a couple of pictures for show and tell. The enclosure is an LMB CR-321. The board is mounted vertical for access to both sides. The

Hi, Chris. Re: The "popping sound" and shift in signal levels- (when you say the signal level goes from -140 dBm to -50 dBm during these jumps, I am sure you are talking about the background

Hearing signals -- that's a good sign. As to the accuracy of the power meter -- it's entirely inaccurate until you calibrate it as it is dependent on the sound card. Once calibrated it should be

Chris: I put my softrock on a calibrated HP siggen and got a very accurate reading with a -80 dBm input. You may have a problem with your input filtering (got the 2 inductors switched maybe?). I

Hi All, I finally got my Softrock up tonight after playing with it last night with no luck. Tonight I can hear stations!! I had a SDR program operator error last night. I took it into work and

Good thoughts, Stan. I agree, the performance of this little rcvr is surprising, considering the simplicity of the hardware. The filtering provided by the software makes for a real powerful set of

That's the feeling I was getting, that is not a simple setup a project and recompile. There is so much more to a programming environment, all the libraries would have to be compatible or your dead in

I have been surprised that no one has been talking about the performance of the SR40. It has brick wall filters, really nice. I have mixed feeling about the noise reduction, but not sure I

Great, Bob, glad you're flying. Maybe our experiences will save someone else some grief :-) Robert Hughes wrote:

Thanks for the response Bill and John (and anyone else who responds after I write this). As soon as I read your suggestions I knew what I had done and so was reminded to get my head back up on my
