Is there a better high frequency Synth.spin code?

I have been using Synth.spin for a project I am working on and it is pretty good for frequencies up to 30MHz. However I need higher frequencies up to 60 or 70MHz. It does not have to be perfect but should be reasonably good "square" wave. I do not need an exact frequency (noncritical & close will do) and am willing to "craft" a few select frequencies if I have to. Any suggestions?

Much improved High Frequency Synth. Better HF signal waveform, fewer spurs and great addition to the SPIN library.

After looking at synth.spin for the first time, I'm very surprised that you think my program works better. I don't do anything that that program does not. Both programs use the Prop's PLL facility to produce high-frequency square waves, and both should produce identical results.
