 | Saipan Modulator Upgrade Project: (Day 1). The work got under way with the first transmitter on January 15, 2007. Its purpose was to upgrade the three Saipan Continental 100kw transmitters with a more efficient modulator system for the purpose of significant savings in electricity. The first order of business was the removal the existing modulator circuitry from the transmitter.
The transmitter high voltage power supply had to be removed in its entirety. This supply provides 13,000 volts DC for the operation of the final modulator stage as well as final RF amplifier stage of the transmitter.
See image #1313 to see what was removed.

 | 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.

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. Year: 2007 Country: MNP Set: 25 Updated: 2007-11-08 19:14:37 |

 | Prayer Card for David and Jan Bayliss, missionaries from FEBC Australia.
David and Jan Bayliss began serving with FEBC in 1994. After postings in Saipan and the Philippines, they moved to Mongolia in 2005, where they were involved in the project to rebuild the WIND FM studios in the capital Ulaanbaatar. In June 2008 they moved to Singapore, working at the FEBC International Office. David served in the role of Field Support Engineer, and Jan trained FEBC staff in the use of radio for community development and health promotion.
