Does anyone know what the worst SWR the Heathkit SA-2040 can tune out (to below 2:1 say).

Don't think it's that simple. Multiple impedances map into the same
swr. But the limits of the tuner are based on impedances. That's why a
tuner might match high SWR for some cable lengths but not others.

SWR is just a scalar number that's easy to measure and very useful when
you're just trying to get to 1:1 where it maps directly into properly
terminated cable.
