Abstract: The invention relates to a method and a system for external, digital coding of a baseband or intermediate-frequency signal. Initially, a digital datastream is converted in a coding device into a digital-baseband signal in the time domain or into a digital intermediate-frequency signal in the time domain. The digitally generated signal is output via an asynchronous-serial interface of the coding device to another device. Such a device also provides an asynchronous-serial interface, which is connected to the asynchronous-serial interface of the coding device. The device reads in the output digital-baseband signal or intermediate-frequency signal for further processing.

Abstract: The invention relates to remote controlling and telemonitoring an unmanned radio transmitter (1), which can be controlled from a center if required. The center is connected to the remote-controlled transmitters via a public or private network and the operational functions of the transmitter are, if required, remote-controlled or interrogated by the center, according to the HTTP protocol, via a connection to a server/browser network linked to the remote-control device; simultaneously, the operational functions are automatically transmitted, without a prompt, from the transmitter to the centre (2) via a checkback network connection according to the SNMP- or HTTP-principle.
