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
Nigel

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.
