True - I believe all the Trimble Thunderbolts came from
Andrew/Grayson/Geometrix WLS2A-24-G or similar Wireless
Location Sensors. I know I removed over 200 T-bolts from
these units personally.

Hi
So in the context of the original post, exactly how many Loran-C disciplined
cell phone systems were there? … errr .. none.
The *only* systems that use any sort of external disciplining are GPS based.
Self contained or “not disciplined” does not count in this case.

Bob,
Nope. Cell phones have been using land-lines for ages to sync up. It was
with the CDMA stuff that GPS phase was starting to be used to
coordinate. GSM for instance does not need GPS on the base-stations, it
even goes to lengthy extends to avoid it. CDMA didn't come into much use

Dear Gerhard,
I think you missed my point by reacting to the technology choice rather
than the function I was proposing.
BTW, I write VHDL, assembler and C code as my daytime work, dealing with
timing.

Hi
If you put a filter on the output of the DIP (or other pkg) XO, you can demo a
sine wave into a scope as well as a square wave. You will likely need a
generator
to power the scopes if it is outdoors so consider that as well. Not all
generators supply
nice clean power ….

Hi
Some form of base cooling is needed on all of these surplus telecom Rb’s
to keep them from an early death. A great big heatsink could do it. A small
quiet fan and a small heatsink will do it. A somewhat larger fan and no heatsink
will also do the job. Any fan mount should consider the magnetic

I used the TAP225K035SRW, from Mouser, and have the PRS10 running again.
In the process of pulling it apart I managed to break one of the glass

Whether it was the lamp temperature change (thermistor) or mecha

Reed Dickinson sells a small oscilloscope calibrator that is well suited
for checking 'scope operation "in the field", at hamfests or when
stumbles across a seemingly nice 'scope in the local electronics store.
It is a very nice, compact instrument. See
