[NLRS] WSJT Modes and SDRs

[John (JK) Kalenowsky, K9JK]

Hey everyone,

In further quest of "education".

Since I know we have a few NLRSers who have experience with the Software 
Defined Radios...and thinking about WSJT software that uses a computer with 
sound card to encode and decode the WSJT messages/modulation BUT an SDR also 
uses a computer with sound card and, in fact, has some particularly 
stringent requirements on the sound card for optimal SDR performance.

SO...my question: Would it require TWO computers to "do" WSJT Modes with 
a(n) SDR?

It would SEEM that, ultimately, software could created for the SDR to encode 
and decode the WSJT "modulation" directly withOUT a need for a second 
computer to "do" the WSJT part but I don't know if it has progressed that 
far as of yet.

Please educate me (us?).
