[R-390] COSMOS PTO EP ADJUSTMENT

[DJED1 at aol.com]

I thought about a synthesized PTO replacement, although I'm really an RF  
engineer by trade.  I found two problems I couldn't solve- maybe someone  
else can help out.  First, you need better than 100 Hz resolution, which  means 
either an encoder with better than 1000 bits/rotation (very expensive), or  
a gear driven encoder.  You definitely need two encoders- one to count in  
Hz and one to count in 100 KHz.  Finally, if you solve all that, you need  
to retain the settings in memory on power down so you don't lose the  
synchronization between the - and the rest of the RF module.  Probably a  simple 
micro could do that.
I thought it would be really neat to have an absolutely linear PTO accurate 
 to 100 Hz over the whole range, but it's beyond me.  If anyone wants to  
help out, just jump in.
