John,
??? I do not hear a carrier at any of those freqs. I double
checked my method by sniffing the XG1 and I hear it at 7.040. What level
would?the clock frequencies be at? I just have a peice of coax on my K2 and
holding it near the SR-40.?The XG1 was pretty loud, but that is a
50microvolt sig. I didn't check it at 1microvolt. I have a scope here, but am
not very well versed at using it. That is something I have been hoping to
rectify since I aquired it. Maybe this is my chance. Hi Hi
??? Do I need?exactly 5 volts to power the SR-40, or could
I use something like a 6 volt wall wart? That is the only way I am going to be
able to get this thing out on the bench where I can get to it.
?

Appreciate the help, John,

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,
John?

I have no way of verifying that. All I get is a little
