I have noticed on my unit that with one particular active antenna (a small magnetic base unit for vehicles), the flag often cycles between normal and open.
It could be that some of the newer, smaller antennas use less current that the older ones and the antenna current sensing on the Thunderbolt can't cope. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Friday, September 12, 2008 2:41 PM Subject: Re: [time-nuts] Trimble GPSDO power supply unit. > 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. > > > > > > -----Original Message----- > From: David Ackrill <[EMAIL PROTECTED]> > To: Discussion of precise time and frequency measurement > <[email protected]> > Sent: Fri, 12 Sep 2008 8:55 am > Subject: Re: [time-nuts] Trimble GPSDO power suply unit. > > > > [EMAIL PROTECTED] wrote: > >> After connecting all wires to the Trimble plug and made a check if > all >> voltage is correct and left the PS unit to run >> on the table without load/connecting to the GPSDO, about 15min got a >> big bang and the Power Supply Unit blow-up. > > 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. > > Dave > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. -------------------------------------------------------------------------------- No virus found in this incoming message.
