Hi Rob.

I took your advice and got a refurb ThinkCentre M700.  I loaded the latest
Ubuntu Server, 22something, and install was very smooth.  I left
everything default and noticed no partition for swap space and that is
something I usually do, but later found a swap file.  Guess in the new
world of flash or solid state drives the whole swap topic has been
redefined.  Fine.  I just let my fav Ubuntu do its thing.

I did the steps below and now I'm clawing my way back with spots.

wsprdaemon started up just fine, but noticed wspr wanted an FFT lib.  I
installed it and poof it works.

It's all humming along as before.  Hat tip again to wsprdaemon for the two
years of making the very most of a Pi4, but now am excited to see how
better the ThinkCentre performs.
