Well, turned out that one of my solder joints was a little light on the solder. MOTM-300 seems to be mostly working, but now some questions for those of you who have built them. I have not yet started the alignment steps, but by default the VCO does not output a waveform in that audible range until coarse setting around 4 for the one I have. Is this correct? Is this something that will be taken care of in alignment if not? Or do I need to keep looking for problems on my board. Thanks for all who gave me tips. Bruce
