Weak pass, as expected.  But I did hear myself towards the very end of
the pass.  Downlink seemed to be about 2 khz low, but hard to know for
sure.  I tried moving the transmit side a bit, but no real conclusion
there on what works best.  Maybe a khz or so low there too.

Next pass is late tonight, if I remember.
