My understanding is that 1000's of these are deployed on commercial ocean
bottom seismographs (Co. name not important) and per my last conversation
with them, that they had identified long term failure's on the CSAC. They
also indicated that they could detect when failure was imminent, and that
Precious little to add to this, just to confirm that back in another life

Now you're really taxing my memory. Radios tuned from 2Mhz to 2Ghz. LO
was high side mix and I think ran from roughly 3-5Ghz, comprised of 4

At the risk of throwing out the bone head answer and assuming this isn't
going on your next space craft, you could just split the GPS serial (my
quick google showed the 18 to be the serial unit vs usb) signal and run a
copy to another comm port..

You're right though - a closer look and the yellow trace does change
