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. 73 John --- On Thu, 3/17/11, Don Wilhelm <[email protected]> wrote: > From: Don Wilhelm <[email protected]> > Subject: Re: [Elecraft] [Elecraft_K3] KR3 SW Receiver. > To: "juergen" <[email protected]> > Cc: [email protected] > Date: Thursday, March 17, 2011, 7:09 PM > John, > > The K3 is an SDR.
