[hpsdr] SDR comparison

[n3evl]

Phil,

Thanks for your excellent explanation.  It's good to know that provision has 
been made for Janus/Ozy to work with the SDR1K without any hardware mods 
however, I expect most users will want to make the adjustments in order to 
maximize performance when using Janus+Ozy.  I wonder if the mods are likely 
to be switchable such that the SDR1K can revert to more or less stock 
condition for use with a conventional sound card again?  Demanding lot, 
aren't we!

Thanks again to you and all the others involved in making this happen!

Pete, N3EVL
