There is a definite CHANGE, maybe it is an improvement. :) I am going to keep working at it, [i]with a little help from my friends[/i], until I get it right. I MIGHT be back to the point at which all the problems are created only by me. That is a very familiar situation for me. Currently, though, it seems that if I only want to use the USB SX-Key to generate the clock at 4MHz, everything is fine. Or, I can run the SX48 module standalone with a 20MHz resonator and it works equally well. But, with the resonator inserted AND the USB SX-Key plugged in, the timing is WAY off. I certainly appreciate all you are doing for me. --Bill ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=415372#m417644 Need assistance?
