NON-RECIPROCAL QSO WITH ZL1HD USING THE "DPOL" FEATURE
(May 3rd, 2015)
The video demonstrates how well the "DPOL" feature described in section 20 works. This capability has been specifically designed to enable EME QSO when mild or even severe non-reciprocity is present.
How does this feature work? Very simple... The protocol consists in simply finding the RX polarity which yields the best trace/signal and entering the callsign of the station of interest in WSJT. The spatial polarization offset information is then extracted directly from WSJT and the optimum TX polarity is calculated and automatically set in the polarity control application upon activation of the "DPOL" feature. Between each sequence, the optimum RX and TX polarities are then fully active enabling QSO despite severe Non-Reciprocity effects.

***WARNING: For Best Resolution for the videos below, it is critical to select 720p HD resolution in the youtube "settings" at bottom right of the player. The 360p default setting won't yield good enough resolution to see the details. It will take several seconds before the High Resolution kicks in, so you will need to restart the video from the beginning when the High Resolution is active and select to view the video in "Full Screen Mode" for best experience...***
