I just received my kit yesterday. I found that the L1 lead, not the body which goes to gnd, was shorted to the gnd plane on the bottom side of the board. I...
I read Bill, KD5TFD'S comments in the AMQRP Future directions. I wanted to do something similar. Be careful of the reference designators! They are from a...
Hi all, Just new to the group. Does anybody experience interference from the PC on 40 meters? What about noise and garbage on the 5 V USB line? 73 Rein...
Got my unit operational this afternoon! I am using the internal Xtal at this time. Hope to hook the DDS up soon. Now to learn how to use PowerSDR properly. ...
Hi Rein, I have built about 25 of the v4.0 SoftRock40 receivers and find the PC noise does not cause much of a problem. When the receiver is calibrated to S9,...
Hi Tony, Thanks for your reply. From looking to the picture on one off the softrock pages I got the idea that the board was directly plugged into an USB...
Hi Rein, Actually I just plug my SoftRock into the USB socket on the front of my Dell 2400 machine. The little receiver plays quite nicely that way and others...
I'm brand spankin' new to the group so didn't see the original thread. Expecting a sensitive receiver to operate just inches away from a wideband noise source...

I have my softrock 40 running. It's plugged into an external USB hub for power, and hooked up to my B & W broadband folded dipole. I can find no birdies...
OK, this person has experience, my views are different and contrary to this persons real life observations. Apparently there is no interference when operating...

Art and all, You missed the point I was making - there are no birdies noted within the limited tuning range provided. This thing, as built will ONLY tune from...
I bought a 16 foot USB extension in case I needed it, and I have matching long audio cables. The monitor is the culprit most of the time, but just in case I...
Tony, one thing I noticed, when just playing around with the SDR software, was the 600 Hz tone that comes from the soundcard (?) at the 7.056 freq. after the...
Hello All, I am afraid that I started the discussion on computer noise in receivers. This was more a general question and not about this particular setup. The...
I don't know too much about all this, but I personally have experienced noise generated from some of the clones I have built in the past. Some of the cheaper...
Hi Stan, Yes, the tone at 7.056 MHz (or what ever frequency you set in as the fixed oscillator frequency) is always there. One of the software guys who has...
I believe the gunk you see near the center frequency with or w/o hardware attached is an artifact of the signal processing architecture, and noise near DC on...
Good deal, Tony, Bill. Well, Bill, I'm afraid I'll just have to be one of those that reaps the benefits of the experimentation done by others. I am new to most...
... noise ... Exactly, and this is one tough sucker to get rid of. The soundcard is one of the most vulnerable spots for letting in spurious signals. Most...
Frank and the group. Until recently, the sound card has been thought of as a secondary accessory. By that I mean it plays the windows warning sound, or an mp3...

I've posted a few updates to the SoftRock updates for PowerSDR. Nothing major, just some bug fixes. Specifically: - Fixed problem using an SDR 1000 in fixed...
Don't know if this post made it to the list, so here it comes again. Sorry for the duplication, if it did. Good deal, Tony, Bill. Well, Bill, I'm afraid I'll...

Bill, I downloaded the update and when I try to turn on the SDR software, I get no response and it goes imediately back to STANDBY. I do not have a SoftRock 40...
Eric, Leon & Stan I saw you were having trouble with Bill's latest software so I just now downloaded it and updated my system to check it out. It came up ...
