I use a system with 8 times 14ele XPol antennas.
I use Linrad 0308 in weak siganl CW and WSE
Setings for POL is:
Channel 1 - horizontal
Channel 2 - vertikal
now Linrad calculated the pol 90 deg wrong !!!
I checked with TS2000 and WSJT and the signals
from the WSE / Linrad with 90 deg are all only on hori.
When i change the antenna Inputson the WSE , i get the
right pol. calkulation.
In MAP65 i have the problem , that i can see a trace - but MAP65 dignt
automaticly. When i catch the QRG and decode manuelly sometime its work.
Any one knows this ?
