One of the key points of OpenHPSDR is that it is open. Linux has the
advantage that it is also open, unlike Microsoft Windows which is
anything BUT open. If I want to run PowerSDR/Thetis I have to pay money
to Microsoft and that bothers me. It pains me that there are all these
programs out there for updating this and that hardware that assume I
have a Windows machine. If you are going to make your application free
to use, why not put it on an OS that is also free to use rather than
assume I have paid for an OS?

We now have LinHPSDR. It supports protocols 1 and 2 of the HPSDR series
of radios concurrently. (Wow, already better than PowerSDR/Thetis in one
respect.) It appears to me to have a MUCH better potential for expansion
than does PowerSDR/Thetis. It is already logically more modular. It does
look like it is clearly moving in the direction you say you would like
to go (something more capable than PowerSDR/Thetis). The key is a
critical mass of people to use it and provide feedback to the builders
so that they have the motivation to keep developing.

So, no matter how deficient it seems now, I think I am going to abandon
PowerSDR/Thetis and focus on LinHPSDR for my future activities. The core
of digital communications exists now with fldigi running on the big-3
platforms: linux, macos, and windows. Looks like that has happened with
WSJT too. The need to run Windows because of a lack of applications for
linux (for hams specifically) seems to have pretty much gone away.

Scott, it is time. We have enough now to actually get on the air and do
nearly everything we want to do, without having to resort to running
Windows. It is time to repartition some disks.
