Jack Phillips - Titanic Radio Operator

Jack Phillips, Titanic Radio Operator - RF CafeJack Phillips, the senior wireless operator aboard the RMS Titanic, played a crucial role in sending distress signals during the ship's sinking. When the Titanic struck an iceberg on April 14, 1912, Phillips and his colleague Harold Bride immediately began transmitting distress signals using Morse code.

Initially, Phillips sent out the distress call "CQD," which was the standard distress signal at the time. However, he later adopted the newly introduced distress signal "SOS" (· · · — — — · · ·) as it was more easily recognizable and understood internationally. The SOS signal was not an abbreviation for any particular phrase; it was simply chosen for its distinctiveness in Morse code.

Phillips and Bride worked tirelessly to send distress signals and communicate with other ships in the area. Their efforts helped to alert the RMS Carpathia, which arrived several hours later to rescue the survivors.

Tragically, both Phillips and Bride remained at their posts until the very end and did not survive the sinking of the Titanic. Their actions in sending distress signals and coordinating rescue efforts have been recognized as instrumental in saving lives and are remembered as acts of heroism.

Some review was performed to help detect and correct any inaccuracies; however, you are encouraged to verify the information yourself if it will be used for critical applications. In some cases, multiple solicitations to the AI engine(s) was(were) used to assimilate final content. Images and external hyperlinks have also been added occasionally.

AI Technical Trustability Update

While working on an update to my RF Cafe Espresso Engineering Workbook project to add a couple calculators about FM sidebands (available soon). The good news is that AI provided excellent VBA code to generate a set of Bessel function plots. The bad news is when I asked for a table showing at which modulation indices sidebands 0 (carrier) through 5 vanish, none of the agents got it right. Some were really bad. The AI agents typically explain their reason and method correctly, then go on to produces bad results. Even after pointing out errors, subsequent results are still wrong. I do a lot of AI work and see this often, even with subscribing to professional versions. I ultimately generated the table myself. There is going to be a lot of inaccurate information out there based on unverified AI queries, so beware.
