Hi
I went back to get a spare Mosaic-T recently and ran into a bit of an
issue. They now are getting serious about âwe donât sell to individualsâ.
Early on, this didnât seem to be a big deal. On the last order it very much
was.

BUT, if someone has used inexpensive SDRs with a GNSS module, I'd be interested to hear about it.
