Our engineers are at work in order to resume transmissions as soon as possible. Our regular broadcasts on 7,125 kHz were discontinued temporarily for a series of transmitter failures last week, which brought us off the air during most of the scheduled times. Spare parts are due to arrive by Friday Dec. 3, and every effort will be made in order to re-start regular operations as of Sunday Dec. 5, 1993. Investigations on the cause of the failures to our transmitter, revealed that surges induced by the local electricity on the 380 Volt power lines which feeds our station, caused severe damages the transmitter's power supply modules, to the automatic tuning system, as well as to computer peripherals used for transmitter monitoring and control. Surge suppressors installed earlier this summer, were defeated by the spikes on the three phase AC line, and exploded in flames. As of Moday Nov. 29, at 22:30 UTC, however, most of such damages have been successfully repaired, and our transmitter was brought into operation during a series of short tests. For safety reasons, however, it has been decided to wait for original manufacturers spare parts and new surge suppressors to arrive and installed before regular operations are resumed. In the meantime, we are considering taking legal action vs. the electricity company which caused these damages, both in order to recover costs, damages, and assure a more reliable power distribution in the future. IRRS-Shortwave can be heard (when on air) MON-FRI between 6-9:15 UTC, and 12-21:15 UTC, and SAT-SUN between 06-22:30 UTC (wintertime) on 7,125 kHz. For more information please contact our office in Milano, or stay tuned to the next edition of our program. And wish us good luck! 73. -- Alfredo E.
