[Elecraft] [Elecraft_K3] KR3 SW Receiver.

[juergen]

Hi Don

I was referring to a direct sampling SDR black box. I am sure a direct sampling receiver with the Elecraft brand name would be a top seller. Lyle probably has  prototypes on his workbench!

I am also sure that a DUC transmitter from Elecraft would also be a popular product. 

Direct sampling and DUC transmitters are in all our futures.
