I know nothing about this, but was surprised at the low price from someone who claims to have been using it in Bend Oregon.
Good for parts only, looks like they are trying to recycle.
It may be functional, but is it useable? If I'm not mistaken, that is a very old unit. If I remember correctly, people can no longer use the Trimble software from that era?
Those things were absolutely bulletproof. I used that civilian version and the military version for many years. Static fast static. PPK then RTK as base and rover. Eventually got OTF. On the fly initialization Then we upgraded with a 4800 rover the chicken bucket all in one receiver and antenna. The battery screwed into the pole. TSC1 data collector. Lots of cables.
You could pre set those up to start logging at a certain time man were they the best thing since sliced bread back in the day. I would not want to tote that sucker and all the cam corder batteries again doing a tops though. lol.
That price is good if that radio still works it should work for today’s equipment. PAC crest. Blue brick.
I don't know about the radio -- if it's not capable of narrow-band transmission it might be illegal to use -- but I wouldn't bother using that setup for RTK unless you're just interested in having a toy to play with. There's far too much weight, bulk and cabling required to make it worth bothering with for real work, and it's GPS-only.
For static work, though, the 4000SSi is still a viable machine. You'd want to upgrade the firmware (to the modified version that was posted here a couple of years ago) to address the GPS week rollover problem, and you might have to replace the internal batteries at some point, but otherwise it's a great receiver for getting L1-fixed vectors. I still have a half a dozen or so of them, and occasionally put one or two to productive use.

These receivers were owned by the UC Davis Geology Department, and were pretty lightly used. I've personally used them on a few co-op projects. Somehow when they were surplused a year or two ago the hard cases and tribrachs they came with got separated, but the receivers are almost certainly still good (though probably in need of internal batteries). For 50 bucks a piece with free shipping, it's a pretty good bargain.
Man you could set those up and log data and send to opus for a cheap way to get on datum for sure. And yes they were heavy. Imagine that on your back with a singars radio which was about equal in weight and size all on your back. We used singars radios in the USMC and did rtk that way. Man to be that young and in shape again. Now I am contemplating downsizing my coffee cup because it’s getting heavy. Lol
