Hi Roy
 
If your unit is generating an output as you report, without 5  volts to pin 
4, then I'd leave well alone.
 
On the current batches of cheaper units, that do require a 5 volt supply to 
 pin 4, they won't lock or provide an output without it.
 
Removing that 5 volt supply from a unit that's already up and running,  on 
two that I've tested so far anyway, causes it to lose lock and the  10MHz 
output collapses, which would seem to be a fairly  strong indication that on 
these units it is needed:-)
 
regards

Somebody  on the list has suggested that it could do damage 
to this variant, to  connect 5 volts to pin 4, to date I have not done 
this, 
Can any member  confirm these details.
