I had also a strong signal at 0Hz. After powering the SR40 with a 5V supply away from the computer and removing the earth connection (only one wire 14m antena), there is only a very small puls

Possible ground loops? Feed the power to the device from an independent floating power supply and see if the gunk in the center of the band goes down. Should not be too hard to try out, I would do it

Nick -- not sure I'd get too hopeful. After inquiring on the Flex-Radio list for people's experiences with Window ME and PowerSDR I tend to believe this is not going to work on ME -- I got no reports

Yesterday I asked for help with the following: Has anyone else had a problem getting PowerSDR to run? When I start PowerSDR the logo comes up but when it says it's initializing DSP it hangs and

Eric, It sounds as though you and I are in the same predicament. The SR40 is working pretty good but the image rejection controls have no affect. Be sure to let us know if you come up with a

Thanks so much, Bill. I'm still going to play with the scope tonight, but I'd be willing to bet the input is to a mono mic input. I had to reach back in the dark with a flashlight and a mirror and

Ahh the small board -- good question as to why is it so dang small -- I think one of Tony's original goals for the gizmo was more of a demonstration vehicle than an experimenter vehicle. I for one

Those were actually two different thoughts. When I inject a signal with my KX1 at 7.040, I get an image at 7.072 which is just about as strong. When I go to the DSP image rejection sliders, they have

I should have said that the image would appear at 7.070, not 7.060- sorry. -Bruce. <bruce.beford@v...> wrote: is trying center

Eric- I think you may be confused regarding image rejection. What is meant is when you inject a signal at say, 7.042, which is about 14Khz BELOW the center freq of 7.056- The image that you are

Hi Eric, Not being able to null the image has usually been associated with the I and Q signals being crossed or one missing. Check to make sure the stereo cable is connected to the board with the

The radio went together fairly easily, though I'm at a loss to figure out why an experimenter's radio is jammed onto such a small board. This might be OK for a production rig, but some room would be

Good Evening Bruce and others, Very good on what you are doing Bruce to get the SR40 running on 30 meters. One comment on your 80 meter operation with the 14.318 MHz clock with the BPF stock.

Good deal, Bruce. Keep us posted. I finally got my SR-40 kits today. Won't be able to start on them until we see what happens with Hurricane Rita. May be evacuating to Dallas. I look forward

Does anybody have this running on Linux? Thanks / Leigh WA5ZNU

I have received the 40.5Mhz crystals I ordered for use in the SoftRock to allow operation on 30M. It is not going to be strictly plug and play. I built my first Softrock with a socket for the crystal,

If the Shuttle had the nice big ole RADIO knob on it, I might have gone for it. But for me, there have to be some concessions to tradition here and the Shuttle looked too much like a video gamers

If you're looking for a knob device to go with PowerSDR you may also want to take a look at the Shuttle Pro -- http://www.contourdesign.com/shuttlepro/ . A bit more expensive, and not quite as solid

I may have to get one of those, Eric. Sounds like a neat feature. Stan Rife W5EWA Houston, TX K2 S/N 4216

Today was like Christmas. The two SR-40s and a Griffin PowerMate showed up today. No time to build today...that will be for tomorrow, but I did have a chance to set up the PowerMate with the
