The other Eric S. [*] asked whether there's reasonable availability of the
Pluto SDR now, and I guessed, on the basis of no good evidence, that there
was. I was wrong. They're backordered until April.
They just released new firmware that supports a rev C board, so presumably
the units due in April will be rev C.
It was requested that the next rev bring out the second Rx and Tx to pass
on the board, but it's unknown whether they're doing so.
