[hpsdr] Horton Local Oscillator discussion paper

[Richard Hosking]

I was involved in the drafting of the PCB.
We used a very wide range VCO, so phase noise will not be terrific.  The 
board could acomodate the National LMX series PLLs  or the AD parts 
which were almost identical. Dividing it down will improve phase noise 
as the dividers dont introduce much.
