An interesting topic, although the article could use some proof-reading. Or perhaps it was Google-translated from Czech?
Also, several technical terms and abbreviations are introduced without any explanation. Still an interesting read.
My try at explanations of terms I've found weird or unclear:
UTO - Uzlovy Telefonni Obvod ~ Area code
"Selective selector" - direct/selective calling in two way radio systems, but in this case it more or less implies what is known trunked radio
stalk - trunk, although IIRC Motorola uses the term stalk for "sub-trunk" or something like that.
In all AMR is essentially analog trunked radio system with the role of operator/dispatcher completely automated and without the ability of direct or repeater calls between nearby stations.
