Saipan Modulator Upgrade Project: January 28, 2007 (Day 14). The transmitter cooling system radiators that are being replaced as part of the project. Today the maintenance staff tore the unit apart for scrap. Here is what the radiator looks like on the inside. It is the result of the interaction of differing metals in the salt air environment of Saipan.

Saipan Modulator Upgrade Project: February 1, 2007 (Day 18). Day 18 began with testing the water-cooling system for the RF power amplifier stage of the transmitter. With power applied to the pump the entire cooling system was checked for leaks. It was good to see water flowing again out of the power amplifier vacuum tube cooling jacket through the Pyrex glass and back into the water reservoir. Because the water flows through components that have 14,000 volts applied to them, the water has to be de-ionized to assure that it is highly resistive and does act like a current conductor.

Saipan Modulator Upgrade Project: February 7, 2007 (Day 24). David Creel replaces the old panel which contained spaces for twelve meters, with one that holds just ten. The meters for the high power modulator vacuum tubes were no longer needed because of elimination of the tubes. See image #1345 for a view from the front of the transmitter.

Saipan Modulator Upgrade Project: February 8, 2007 (Day 25). The Russian language programs of “Radio Teos” went to air on this day, in the evening at 0730UTC, the first broadcasts on KFBS with new solid-state modulation systems. As the meters showed, the transmitter was run at a full 100,000 watts and full 100% modulation. The “controlled carrier” feature was not fully tested and in operation.

Saipan Modulator Upgrade Project: February 9, 2007 (Day 26). Project completed! The morning hours today were spent in training on how to properly adjust and operate the transmitter with the new solid-state modulator. In the afternoon the "controlled-carrier" feature was put into operation.

In the original transmitter design an RF signal of 100,000 watts was generated regardless of the presence of audio program material. A huge amount of power was consumed to generate this signal called a “carrier” even during the pauses in speech. The “controlled carrier” feature suppresses the RF sign generated when there are pauses or silence. We are currently using 3db of carrier suppression. This means that when no audio is present the power output of the transmitter is 50,000 watts. With modulation, the power output varies between 50,000 and 100,000 watts following the audio variations. This means less power consumed and lower power bills.
