You might try doing a cold reset. I had the same issue and that got it back. You need to use the trimble software.

My bolt has suffered a significant loss of sensitivity, the AMU values have dropped 30 dB. It is not the motorola antenna or feedline, works fine on an Oncore. This appeared to have happened when I tried to operate 160 meters!

I think that the TBolt's schematic(s) are sort of HolyGrail for TimeNuts. On Tue, Dec 11, 2012 at 11:43 PM, Tom Miller tmil...@skylinenet.net wrote: You might try doing a cold reset.

They are pretty simple, so I am amazed that there has been no major attempt to reverse engineer them. The GPS front-end chip I haven't been able to find a datasheet for, and then the CPU/GPS-baseband chip seems to be an ASIC, but most pins should be fairly simple to explain. I have only one Tbolt, so I don't want to put that into pieces (again).

I have 4, two of which have had the low phase noise OCXO removed for use in a PN interferometer. The TBolt output buffer has relatively high phase noise.

On the other hand, it's not all that many pins, so a bit of advanced guessing should not be too hard to do. Tossing a sine in I bet you will find mixed-down versions occuring in one or two IF-filtered versions before breaking free as digitized version. Most probably as 2 bits and clock going to the GPS baseband chip. This is what a typical GPS front-end chip does. You toss it a reference frequency, and it steps it up, amplifies the GPS signal, mixes it down. It will be one or two SAW filters with balanced outputs and inputs. Fairly trivial stuff.

I think that the TBolt's schematic(s) are sort of HolyGrail for TimeNuts. Some French time nuts told us they already have one. It's very nice. /tvb ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

While enjoying Monty Python and having seen the movie at least twice, I fill my brain with other stuff... labeled TF amongst others... There is at least one better time-joke in that movie... thou count shall be three...
