Hi Chris,
Linear to circular polasation was done Friday afternoon with a central
freq of 1666. This experiment (and VT11c3) has a central frequency of
1650. This means that we could have adjusted the inputs to the quadrature
hybrid for a better channel separation. We were reluctant to touch it
last night.
Regards,
Brett.

Hi All,
Fringes to all antenna for vc022 (fringe test for v211a). Hobart has a
1 sec offset again. Polarisation separation for Hobart is not very good.
Fringes at http://pentane.ssi.swin.edu.au/~cphillip/vc022 UT 20:22:02 with Hobart
Cheers
Chris
