[Elecraft] P3 ?

[O. Johns]

Dear Larry,

Big question:  QUADRATURE OUTPUTS??

It seems to me that if Elecraft does provide quadrature outputs from  
the P3, then, besides being a stand alone panadapter, the P3 might   
also effectively replace the LP_PAN unit .  You could just plug those  
quadrature outputs into your sound card and then use PowerSDR-IF stage  
and LP_Bridge on your computer just as if you had an LP_PAN.

Why do that?  If you just want a panadapter, then there is no reason  
to.  But if you want to use other features of PowerSDR like an  
alternate set of DSP implementations, maybe better audio, maybe more  
resolution on the screen, etc., then you can use those quadrature  
outputs with your computer and Power SDR to get that.  You'll  
effectively have a FlexRadio receiver on your desktop (K3 front end,  
PowerSDR back end) along with your K3 and its panadapter.

One benefit of the P3 is likely to be important only to people who  
have problems with RF in the shack.  The LP_PAN setup can be a rat's  
nest of cables and adapters.  It is very vulnerable to RF, and hard to  
get clean.  The P3, however, is all in one metal box, and is  
presumably tested by Elecraft to play well with the K3 when  
connected.  This could be an important benefit.  Of course, you might  
lose that benefit if you then connect things to the quadrature  
outputs.  :-)

Hope this is some food for thought.

73,
