This 3,5 KW transmitter operating in the 87,5÷108 MHz
band, uses 6x800W amplifiers in parallel mounted for the cooling
in only one heat sink. A failure in one RF amplifier will reduce RF
output power, but it will not affect operation of the other in any
way. This redundancy is the key to the excellent reliability of this
Operating frequency can be set up in a few seconds by the
synthesizer. The equipment is fully microprocessor controlled.
These transmitters are ideally suited for unmanned
stations, in fact they do not require periodically maintenance and
are fully protected.
The installation is very fast and maintenance very easy.
It can be equipped with an RDS code built-in.
