I think the Maratrac is based on the MaxTrac radio. As
such, you'd probably have to go through the Board
Replacement -> PA Alignment procedure which sets the
output power at 16 discrete frequencies.
On Radius radios (cousins of MaxTracs), the freqs go
from 440-470, but on MaxTracs they usually go from
449-470. Some radios can be aligned to cover 440-470.
Not all radios will work below 445 MHz without some
other retuning, so even if the PA output is properly
aligned, there may be other issues.
You need the appropriate radio service software and
paraphernalia that goes with it, plus a dummy load and
a power indicating device (wattmeter or service
monitor).
