Roy, you are always saying I should be using voltages for
my calculations and that's exactly what I did.

--43.4 deg 600 ohm line--+--10 deg 100 ohm line--open
Vfor1--|--Vfor2

With 100 volts at zero degrees incident upon the open
end of the stub, I get:

Vfor1 = 143.33 volts at -46.6 deg
Vfor2 = 110 volts at -10 deg

for a phase shift through the impedance discontinuity
of 36.6 degrees. What do you get?

Don't anybody hold his breath waiting for an answer.
