[DSP-10] CW transmit has a raspy sound

I have been playing around some with an HP 141T spectrum analyzer I just 
purchased and have been looking at the local oscillators.  While the 19MHz 
osc looks fairly clean, the 124MHz osc does not. As a mater of fact, it is 
pretty bad in my opinion.  I don't know if anyone else has had the 
opportunity to look at theirs but I've put up a web page on my web site 
showing what I've found.

When taking the measurements, I've removed the coax jumpers from the 
outputs of the oscillators and used a pigtail coax with an SMA connector to 
get the signals to the analyzer.

The URL is http://www.aa1yn.com/dsp-10/spec_ana/ and the images are linked 
to medium resolution images.

Any thoughts? Any questions? Any ideas?
