Report out on AO51, mode LU (23cm up, 70cm downlink)

Uplink: Kenwood TS2000X, 10W, 35 element TONNA
Downlink: Kenwood TS2000X, 2x7 elements Cushcraft

Need to switch polarization during the pass
(LHCP, RHCP, H, L) on the downlink for strongest signal.

Lots of QSB on the uplink, signal varying from noise free
to not at all able to copy.

Used HRD for automatic doppler correction / control.

This evening I also had a 50% complete QSO with Ib, OZ1MY.
