This idea of digitally encoding the signal is feasible. I work
with remote controlled industrial cranes and locamotives that
operate
on 72MHz. In one area we have 3 cranes operating on the exact same
freq with different digital addresses without any interferance.
The industial area in the original post may have some of this
equipment operating there. This could be your interference!! Most
of the equipment I have worked with, are on the lower channels of
the 72MHz band.
