Technical information

The frequency range of the heating facility is from 4.5 to 9.3 MHz. The facility consists of three 250 kW broadcasting transmitters and a 144 crossed dipole antenna-array with dimensions of 300 m x 300 m. At the middle of the operating frequency range (4.5 � 9.3 MHz) a maximum zenith gain of about 260 (~24 dB) is reached, the ERP of the facility is 190 MW (~83 dbW).

Heating facility in Ramfjordmoen consists of three antenna arrays and 12 transmitter amplifiers. The maximum power of each transmitter is 100 kW. So the total power of transmitter system is 1.2 MW. The radio wave frequencies can be modulated by frequency synthesizer. All 12 frequency synthesizer are connected to one common frequency source. This system is of cource computer controlled.

Gli stati uniti, se interpretiamo 3,981 come 3 MEGA, dovrebbero lavorare con 73 e qualcosa MEGA di potenza, facendo la somma di tutti gli impianti, praticamente degli sfigati planetari

FAIRBANKS — After spending a quarter-century accumulating astronomical equipment in Two Rivers, of all places, the UCLA physics department plans to spend this year doing a little housecleaning.

The Los Angeles-based university has shut down the HIPAS Observatory, a remote site it maintained at 26 Mile Chena Hot Springs Road that was used for atmospheric research.
