[600MRG] Polarization tests at W5EST

[James Hollander]

Thanks for several reply-e-mails with encouragement.  Since I'm receive-only, not Part 5, probably the nearby XSH/15 is the relevant TX corresponding to my receive setup.  
>>Now you need someone to do the same for you on TX.  N0UU 
Around North America and in UK/EU, the WSPR map shows numerous Part 5 stations that have good TX and good RX and also several pairs of stations where a Part 5 station and a receive-only station are situated very close to one another. 

BTW, if two stations had antenna systems that are mirror-images of each other, I'd expect Faraday rotation to rotate in about the same compass direction for each arriving transmission into each receiving station. (Hope I understand it right--at least for roughly North/South paths along geomagnetic field lines. Might not work the same way East/ West) 
 
Polarization reception improvements here could include:
  --Noise cancellation in each common/differential mode path to allow nulls and polarization variation reception for much farther-away 630m stations.
  --Working out a circuit that would conveniently determine the polarity/direction of polarization variation, not just the magnitude of SNR.
  --Measuring 630m elliptical polarization as well as simple tilt (variation) away from the polarization reference.  
  --Antenna and circuits to help measure the compass direction of tilt away from vertical polarization. 
  --Formulas and circuits/software to reliably go from measurements of common/differential mode currents to estimates of the actual polarization orientation of the arriving signal wave.
