The technology used in the USB based device coming from HPSDR is 
identical to that provided by the extremely expensive sound cards (Lynx 
L22, One, Two) and the Creative Emu1212M and greater cards.  If you can 
hang on to what you have for  the time being,  I would definitely wait 
to see how this turns out.  It is my opinion that it will NOT be cheaper 
than the sound cards you currently have unless you factor other 
considerations into the equation.

To use the Janus device coming from HPSDR,  you will also need the Ozy 
and Atlas.   Atlas is a backplane and Ozy and Janus are two plug in 
cards for the Atlas backplane.   We do not have firm final numbers on 
the production and sale of these devices but it is my opinion it will be 
more expensive than the Roland FA-66 if the HPSDR system is purchased 
assembled and tested.  Most will be completely unable to solder the 
components on the board and you should not attempt it.  Most should buy 
the built and assembled boards.  When they are available, they will be 
on sale from TAPR.   So factored in to the cost of the boards will be 
the cost of the boards, parts, contract manufacturers,  packaging, and 
shipping and the NRE that went into the boards as well as a "TAPR tax" 
to support further projects and offset TAPR fixed costs.

The mitigating factor is that Atlas and Ozy will be used for the 
foreseeable future as the "hub of operations" for all HPSDR projects.   
So the cost of Atlas and Ozy can be amortized over all of the projects.  
If you are NEVER going to do any of the other projects then the cost of 
this sound card replacement solution will not be cheap by anyone's 
definition.  It should yield the absolute ideal performance for SDR-1000 
in particular and SDR things in general.  Bill and Phils  and Lyle have 
busted their humps to get this together and it will have a major impact 
on SDR performance theoretically.   We need to subject the board to use 
in a few full power stations and to serious dynamics studies to make 
absolutely certain.

the same way: you send signals here, they receive them there.
The only difference is that there is no cat." - Einstein
