The equipment is W5IU's. The radios are two FT-817s.

The antennas are homebrew, circular polarized yagis (no relays, sense can
only be changed by adjusting the feedpoint) based on WA5JVB's "Cheap Yagi"
designs on a homebrew mount made of PVC pipe and pipe fittings along with a
tripod. There are two mast-mounted RF-switched Advanced Receiver Research
preamplifiers, the MSP144VDG-160 and the MSP432VDG-160. Feedline was
LMR-400. The setup worked quite well, with S9+ signals on all satellites.

Everything was powered by car batteries.

No automation was used. Although a laptop with SatPC32 and CAT cables to
connect to each radio was available for Doppler, we chose to operate
manually. The person manning the antennas was using an iPhone app to follow
the satellite.

Thanks for the QSO on SO-50. We did not expect much success on the pass I
worked you on due to the position of the building. The satellite just
barely rose over the building on that pass.
