I did it again...

Well, over the weekend I built another DDS module. This time I was
successful in putting an AD9850 DDS chip on a 28-pin DIP header. The
AD9850 uses a 120MHz oscillator, and create frequencies up to 45MHz.
Right now, it is programmed in parallel with the S&S engineering DDS
module AD9850. I can create a computer program to program the module
from the printer port like the AD9832 module built earlier this year.
I have also started playing with the PIC chips. I have not created a
program for the DDS yet, but will soon. I have copies of programs by
others to control the AD9850, and can modify them for conrolling both
that DDS or the AD9832.
The spectrum analyzer is almost done. I am waiting for the tracking
generator kit to finish it. I am also thinking of putting one of the
AD9850 modules in it to create a marker generator.
If I am lucky enough to be successful in creating a mini-pc board to put
the AD9850 on the DIP header, I may be asking if anyone is interested in
me making a few. I am NOT going into business doing this.
Next steps are to finish the network analyzer, three meter bridge
cisruit, and then finish my LF receiver. It never ends!
