GENERAL SYSTEM DESCRIPTION
2.1.- Introduction.
MT-MR Platinum Radio Link System is a typical STL (Studio-Transmitter Link) used to carry aural information from
Production Studios to a distant Transmitter station. It is developed for practically all frequency bands below 1 GHz
that are generally used for this type of service. Both transmitter and receiver are fitted with high-stability PLL-
controlled oscillators, with TCXO reference frequency source, to accomplish the most severe frequency-stability
Rules and Regulations around the World.
MT-MR Platinum system is capable of carry a high-quality stereophonic program and three specialized SCA
channels used for commercial audio, low-frequency data transmission or telemetry/telecontrol purposes. This Radio
Link not only can work as STL point-to-point system, but it can also work as multiple-repeater Relay system in any
configuration, allowing to link very distant Transmission sites with its Production Studios. Facility of audio dropout at
each repeater station allows the creation of province or national chains having multiple Transmitter Stations.

As we said before, this Aural Radio Link can be built, at Customer request, in practically any frequency band
designed for these linking purposes. Originally designed for 400 MHz frequency band, further development of new
circuits will expand its range to 300-370 MHz, 470 MHz and even 900-960 MHz well-known frequency bands.
