That's okay! I wanted input from the user community and I'm happy to
have it - it's got people thinking and talking. That's good!

Nah! No misery, really - lots of good ideas and lots of ideas on how
people want to use the HPSDR.

That's okay! Yes, it makes the task a little more complicated, but I've
not yet come to the conclusion that all can't be happy. Yet. ;)

I've not yet either, but did have a thought today. If a power amp is
designed for the HPSDR, it will likely be more than one slot thick -
heatsinks and transformers and extra power wires to get in the
voltage/currents needed. So, say if an 8-wide case is found, we can
simply say that the extra three slots are for a future power amp (or,
some yet-unknown card) that needs more space.

I'm having a hard time visualizing what you've described above - spent
the day in a forest fire (which they call a controlled burn) at work and
am a bit foggy from the antihistamine due to all the smoke. I'll
re-read this tomorrow and draw some pictures to myself and I'm sure I'll
understand.

Brainstorming is good!
