WD successfully run on a Chromebook

I was recently out in a "quiet place" to make noise floor measurements of my active antenna system.  I did indeed find such a place which could reach the noise floor limitations of my system and propagated noise up to mid-HF.  At the same time I decided to try to spot WSPR on the only computer I had with me, a Chromebook. As you may know the Chromebook is rather "cloud based". It doesn't like to do much of anything off line in a location of the sort I was using. The Chromebook runs Chrome OS but also has a virtual linux machine app available.  This is a command-line-only application with no GUI. However,  I did manage to install Rob's wsprdaemon on it (after manually installing by changing a "." to a "-" in the libfftw library install request) so that it installed OK.  

Because I had no Internet connection at the remote site where I was measuring and I had left the GPS antenna at home, I had to manually adjust the portable Kiwi's clock using a time/frequency station.  That left only the time synchronization  to be set. This turned out to be the hardest  and I finally just set the Chromebook while on the Internet and left it running while I drove to the remote site.  There may be a way to allow the Linux application to set the Chromebook time but I haven't yet found it. The usual 'data ...' method was not allowed.

But the good news is that in a pinch, if stuck with only a Chromebook, wsprdaemon and a Kiwi can successfully spot WSPR and noise data and then once returned to Internet access, load it into the databases.
