Frequencies are well know and established by monitoring past usage. The equipment itself may or may not be sold as scrap but physically demolished by
several means to render it it unusable as well as unidentifiable, if there are any national security issues involved. The technology used for this
type of communication is well known and understood to a limited extent. I can't believe I'm about to write this.... HAARP is/was part of this type
of technology. HAARP is blamed for many things, but it has some legitimate uses.
So much of the "official" radio traffic has gone to satellite usage for one reason or another. Even the old, well established, official use land
lines have been replaced with fiber optic network quality communication.
The old stuff is just that, old.
I find these articles interesting when the stuff is decommissioned around the country.
