[Linrad] Re: Map65 reports "No Rx data"

[Edward Cole <acsalaska.net; kl7uw@xxxxxxxxxxxxxxxx>]

Joe, etal:

Currently, I am just following the discussion but have not yet 
installed Linux.  I have Linrad for windows operating and MAP25, but 
wish to use them both on the same computer using input from the 
SDR-IQ.  Is localhost pertinent to Linux or is it available running 
win-XP?  Last I heard MAP25 was not yet set up for use with the 
SDR-IQ (something about the sample rate).  I am using a duoCore-2 
2.33 GHz Dell with 2GB memory.

I can run with my soundcard with output from the FT-847 but that 
offers no advantage over JT65 as it is limited to 2500-KHz bw.
