[time-freq] State of manuals for RefLock II?

> |Start with the the lowest profile parts first.  That will be

> |value at a time.  Mark off the designator as you populate the 
> |parts.  If you need help in knowing where the part goes, take 
> |a look at the assembly file on Luis' web site.  It has a 
> |magnified view of the silkscreen.  You can double check with 
> |the schematic.
> |
> |All the parts should solder onto the board in a straight 
> |forward manner.

> |I trust you have done surface mount parts before?  I use a 
> |magnifying glass for most parts.  But the CPLD I soldered down 
> |under a stereo microscope. All the remaning parts can be done 
> |under a lighted magnifying glass.
