What I can say is the QSD has an inherently positive IP3 if the load is proper. It depends on the impedance presented it to to act correctly since in the four RC circuits, the R is dominated by the antenna. I do NOT attest to the +23dBm simply because I have not measured it. People are not paying $29 to get a high performance receiver. I think the idea is to have a very low power version where we can do all sorts of things from running it with the fancy software, PowerSDR, down to the Micro908 with Lyle's DSP board and new DDS board.
Inexpensive is the right word. Bob observer35 wrote: >Hello All, > >On one of the announcement pages for the softrock40 the IP3 is given >as (minus) -23 dBm.
