Gents,
Sorry if my mail give the impression that I am complaining about the
blown PSU, it is because my English is not as good as it should be.....
just wanted some help to repair the unit.....and in the mean time I
have already installed the GPSDO into a nice small box with a home
built PSU and now looks like a table-top "Frequency Standard" instrument
NEW SUBJECT...
When I use the GPSDO direct from an active antenna after power
interruption the unit recover relative soon,.....
but when the GPSDO used from a antenna distribution box and this way
the GPSDO sensing the antenna is OPEN, then after power interruption
the unit can not recover.......???????----------even after a long
period......
Anybody had the same experience??????????
Thanks and regards,
Ernie.

On my unit the PSU was not working when it arrived.
The quickest solution, for me, was to go to a local electronics shop
and
buy a new unit.
