[hpsdr] Multiple Independent Receivers & Mercury

Hi all,

I have just watched Phil's excellent presentation on Mercury which was recorded at an ARRL TAPR event last year. I really recommend that everyone here should watch this DVD. 

As I understand it a single Mecury is quite capable supporting multiple independent receivers. I believe Phil said it could do 6, and only limited by our USB bandwith. The only reason that we currently have a single max 192KHz was so that we could use existing software like PowerSDR.

I was wondering if there are any plans to implement a second independent receiver and how difficult that may be. PowerSDR supports a second receiver for the Flex 5000 so that might be a basis to start with, though we may also need FPGA code changes as well.

I know some people have been talking about dual Mercury boards, but I think this would be unnecessary.

Food for thought

cheers
