Fitzroy Radio Silence Wall Clock with QuickFix
- Product Code:
Radio Silence Clocks: Tragically, the radio-signalling equipment carried by RMS Titanic was of little use, since the distress signals sent after hitting an iceberg in 1912 went unheard for several hours. The disaster spurred an international review of maritime safety which made several recommendations, one of which led to the introduction of radio silence periods. These are three-minute periods immediately following each quarter hour reserved exclusively for making, and listening for, distress calls. The green sectors represent silence periods on the SSB (Single Side Band)) distress frequency of 2182kHz, as carried by commercial and some pleasure craft. The red sectors are for Morse code distress signals on the 500kHz band, as used in radio telegraphy. Radio room clocks have traditionally been marked with the sectors as guidance for the operators.
The unique QuickFix system allows the instrument to be locked hard to a bulkhead or wall but removed, in seconds, by hand. The instrument is supplied with a base plate which is screwed to the wall or bulkhead (instructions and drill hole template included). The instrument then simply slots over the base plate and with a gentle twist, is locked on. A reverse twist removes it again. This makes changing batteries easy, removal for storage easy, and avoids the tricky job of not scratching your polished case when screwing the instrument to the wall! QuickFix can also act to seal clock mechanisms making them waterproof.
