This, for me, is a dealbreaker when it comes to high end SDRs. They do
require top end computers. They also require frequent updates, and
after enough updates even your (currently top end) computer will again
become obsolete. No thanks.

They specifically require DirectX to run the soundcard DSP. I am not
going to spend $250+ for the privilege. Intel needs to write a DSP
routine that runs on Linux.

Even with the cost of a computer and software the Perseus is pretty
reasonable. The filter performance exceeds the majority of receivers
and tranceivers on the market:

I was going to get a Flexradio until I found out you need Windows to use
the thing. I got the Elecraft K3 instead. $299 for an operating system
is insane.

One of the problems with a radio that requires a PC to do the demod is
you can't run 3rd party decoding software on the demod signal since
the sound card is busy doing the demod. [Hope that makes sense. ;-)]
For example, PC-HFDL requires a sound card, but your sound card is
busy with the actual demod. I've got a SDR on loan and it's going
back. I find the need for a computer in the field to be a real
hassle.

To be fair, it's more like $100 for the OS. I put OEM win7pro on my
desktop for a bit over $100 when Fry's had a sale. That all said, I
rather have linux. Incidentally PC-HFDL works fine under Wine. I guess
it didn't need directx.

This'll work with the Perseus and windows.
