L band  Needs at least 3dB more power out of both R and LCP.
         The synch detector signal was very low. Is it even
         connected?

X,C,S  can see synch detector 5% (10% at X band, a bit high)
        and sampler rms looks OK.

        However, no fringes at any of these bands, in parallel
        or cross-polarized correlations. Feed covers left on?

K,Q:   did not try yet.
