The reason why I added this section is partly for the historic value, but also because some of the listed items may be converted for ham use. This is a low priority section. I have no ambition to make this a complete library of every single analog cellphone ever made. A selection of various pocket, portable, mobile and system base units will have to do for the time being. Items will be added at a very slow pace. As a sidenote, the new european digital GSM network (2G) officially rolled out in july 1991. However, most european countries didn't launch their systems until 1992. This basically marked the start of the demise of analog systems.
