Joe et al:

I find I'm a bit behind the curve to be getting ready for next 
weekend's EME contest, but I had wanted to try MAP65.
Here's what I have working now:
1.  Standard JT65B on 2m-eme:  4x 3WL xpol - two cascaded preamps - 
FT-847 - SB-16 soundcard/computer P3-866...works FB.
2.  Alternate SDR:  4x 3WL xpol - two cascaded preamps - DEMI 144/28 
- IF amp - SDR-IQ...runs either Spectravue or Winrad.
3.  What I want:  4x 3WL xpol - two cascaded preamps - DEMI 144/28 - 
IF amp - SDR-IQ - P3-866/Linrad to Lenovo P4-2K/MAP65

I haven't gotten windows Linrad to run, yet.  I have MAP65 loaded in 
the Lenovo laptop but yet to test it.  I have a local router for IP 
linking the two computers.
I realize that I will not have the full polarity system with this 
setup.  I gather that MAP65 is fixed with 60-KHz BW for now.  I find 
the SDR-IQ works at 50-KHz on my P3-866 pretty well (about max on cpu).

Do you or Lief know of anyone who has the SDR-IQ running with Linrad or MAP65?

I need some set up pointers/parameters for Linrad(win) and MAP65 to 
run the SDR-IQ.
I'm willing to write up the process for my website to help other 
SDR-IQ owners get going on MAP65; the existing webpage 
is:  http://www.kl7uw.com/SDR.htm
