I have heard R. Victoria on this frequency before, so I think you are
correct on the ID. When I heard them (?) I did get a positive ID and
heard street routes given for a demonstration for disabled people that
matched names of principal streets in the southern cone (Villa el
Salvador) of Lima.

I am not sure of their transmitter site, but almost every emisora in
Lima is sited up on Morro Solar, a small mountain that projects into
the sea south of Lima. It is quite prominent, and was strategic enough
to have been the site of one of the major battles for Lima during the
Chilean invasion of 1879.
