Hi All, I purchased one of these "red box" t'bolt from this Israeli seller and it arrived a couple of days ago. I can confirm it has the Trimble labeled OXCO and firmware FW2.12. Also interesting is that it seems to run happily with the supply backed off to 17V.
I've taken some pics with the boards spread out and uploaded them to Didiers site. The file is called RedBoxThunderbolt.pdf and should be available shortly. As with many things found on fleabay, a gamble is involved. In this case it seems to have paid off. Is it possible (and is there any benefit) in updating the firmware? cheers, ian > Date: Fri, 23 Mar 2012 09:47:59 -0400 (EDT) > From: [email protected] > To: [email protected] > Subject: Re: [time-nuts] Trimble T'Bolt > Message-ID: <[email protected]> > Content-Type: text/plain; charset="US-ASCII" > > Hi Stan > > With a 99 date code that's looking pretty old and will more than likely > have the earlier Piezo oscillator as per John's comments here.... > > _http://www.ke5fx.com/tbolt.htm_ (http://www.ke5fx.com/tbolt.htm) > > It's certainly not one I'd go for. > > Regards > > Nigel > GM8PZR > > > In a message dated 23/03/2012 13:34:42 GMT Standard Time, > [email protected] writes: > > Hello The Net, > > On Ebay: 120880795618 > > > Is this a very old T'Bolt or the newer e T'Bolt ? > > I like the single power supply even though it is 24VDC > > Stan, W1LE Cape Cod > > _______________________________________________ _______________________________________________ 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.
