Especially in Germany the Ericsson Compact 9000 has been used by radio amateurs frequently. After the commerial networks had been switched off a lot of these transmitters (including the RF amplifiers) were available to radio amateurs.
On some german webpages information can be found about this equipment, but this is slowly becoming less. Therefore this website offers some details.
