It is true that MAP65IQ only decodes a single polarity, but if you 
have a dual-pol antenna system, you can switch pol on the nezt 
sequence and capture any signals that are coming in on that 
polarity.  I would guess that one would sample the spectrum with 
MAP65 every 5-10 minutes else you would have information 
overload.  Activity would not change that rapidly that one needed to 
capture everything in one minute.  Obviously, not as sophisticated as 
WSE Rx into dual channel Linrad, but I think it is workable.

I have a dual-pol eme station but will run my 2m Rx signal into a 
splitter feeding my FT-847 <--> JT65 (computer#1) and simultaneously 
into a DEMI 144/28 xvtr feeding my SDR-IQ --> Linrad/MAP65iq 
(computer#2).  So I will be able to watch the eme subband on the 
selected pol, switching pol as desired.
