[hpsdr] 2 hpsdr questions

1. ozy does talt to Linux just fine.  On Linux you must use libusb-1.0 
as opposied to the default libusb.  The code to initozy the FPGA and 
write to I2C can be found in two places at this point.

svn:206.216.146.154/svn/repos_sdr_hpsdr/OzyJanus-Jack

you will need to get the latest *.hex and *.rbf file from Bill's KD5TFD 
Powersdr directory and

The you will need software that runs on Linux (ghpsdr, sdr-shell, 
acorn-sdr or java-sdr),  additionally a very nice software that will run 
on Linux but does not talk to HPSDR FPGA is MaxSDRII.  This was written 
for another radio (qsr1) is a similar hardware.

The current version of powersdr will not be ported to Liunx as it is 
written in C# and the linux C# compiler does not seem to be stable 
enough to handle the realtime processing necessary.  Powersdr is 
borrowed from the Flex people with their permission and therefore 
developments for HPSDR are addons. 

I understand Flex is in a the process of redesigning their software.

2.  Several people would like to do something like this. Multiple 
receivers on one mercury with on antenna are possible.  None of the 
current software was designed to accommodate your case.  There is lots 
of open source code pieces if you want to take on programming and 
multi-receiver Mercury.  Some experiments have been tried with softrocks 
and special version of Rocky for diversity radio reception but the 
results did not warrant further development.

Hope this helps and I look forward to your contributions to the HPSDR 
project.  Links to most of the currently developing software can be 
found at http://hpsdr.info/resources.html
