I`ll gladly leave discussion of the gear in Cuba to wb. I already said the 4765 spurs were *not* like the 13700 ones. Glenn

Bejucal (RadioCuba #2) of the 1965 years era,
each 50 kW;
and combined also to 2x times as 100 kW in total.
(11840 kHz R Moscow relay .... for example)

13 SW masts of 1965 Sowjetunion Leningrad firm design

MW origin TXs was NEC Made in Japan in 1970,
TESLA CSSR in 80ties,
Chinese from 2002y onwards,
and also some NAUTEL - Made in Canada - origin.


Glenn, you should include the technical infrastructure
used at RadioCuba centers in the discussions.

Your description of intermodulations on the SW bands
from low transmission strengths portion -
also FM-like scratching audio tones appearance,
you have to look at each transmission center separately,
not to mix Bejucal 4765 kHz
with 13700 kHz Bauta gear example intermodulations.

technical knowledge.
The equipment provided by RadioCuba is very different
in year of construction and design.
