Glenn,
This unit is way before my time, so not familiar with it. A lot of
guys use a "noise bridge" to help adjust a manual tuner. As you put
out a low power carrier from the radio, you will adjust one or two
knobs (depending on the tuner) to get the SWR down. The needle will
be moving around a bit until you get it to a flat SWR. Not sure if
the app will be able to follow this. When using a noise bridge, you
listen for a null in the sound produced by the bridge to indicate flat
SWR. There are other types of audio devices that generate a tone that
gets lower in pitch as the SWR drops. Flat tone means flat SWR.
Again, a resonant antenna (or antennas) for the band (or bands) of
operation will negate the need for a tuner in the first place.
