Hi Stan,
the S9 carrier at 7.056 is normal (even without the device powered).
If you have a scope you can should check the clock signals that are shown on the schematic (QSD Timing Diagram) and also check that they are all getting to U5.
If you do not have a scope you could tune a receiver to the 28.224, 14.112 and 7.056 clock frequencies to check that they are being generated but you will not be able to check that they are getting to U5.
If the clocks are OK I would check the wiring of T1. I have 2 SoftRock40's and when I built the first one I did not get the wiring of T1 correct and all looked OK but no signals.
Hope that is of some help.
Regards,

I finished the SoftRock last night and I plugged it in to one of my
USB hubs...no green light from the LED. I put it back on the bench and
verified everything and all looked ok. After messing with it for a while and
still not getting a green LED from my USB hub, I decided to plug it in to
the USB on the back of the computer...GREEN LIGHT. Wondering why the USB hub
doesn't put out 5 volts, but will worry about that later. I thought that the
5 volts daisy chained from device to device.
So, it lit up, but I am not receiving anything. The latest binary
was acting really weird on my computer, so I reinstalled PowerSDR and then
unzipped the binary's from August in to the SDR install. It appears to work
ok now, I think. I have no way of verifying that. All I get is a little
background noise (I got this before though) and a solid S-9 carrier at
7.056, but this is ALL I ever got from the software whenever I would start
it up with NO hardware. So, I hope this is making sense, the SR-40 is either
not working properly, or the software is not working.
I can play the canned .wav files and that works, but nothing from
the SR-40. Made sure my LINE-IN port on the soundcard was selected, and
checked that the volume was up sufficiently. I don't know what else to
check, or how to check it. I am electronically challenged, sorry guys. Plus
it is hard to get back behind the PC to do anything. I don't have a 5 volt
power supply. Can I use a 6 volt wall wart?? I didn't see a 5 volt regulator
on the SR-40.
Can someone tell me where to start? And what about the S-9 carrier
at 7.056?? Is that supposed to be there?? I do have an XG-1 signal source,
but I'm not getting anything to the software.
Thanks,
