For some reason I assumed that the calibration tape that I have (from an e-bay seller nielsfup2010) was two track because it was made on a B77, but yes thinking about it full track would be the optimum layout to do the azimuth/phase adjustment. May be I'll try playing the tape backwards and see what I find.
