Using radio or satellites, right?It's funny, we were the guys that the bridge got their time from, but after the time tick, their chronometer was a superior timepiece.Our Chelsea clocks kept time within 20 seconds or less a day, good enough forradio logs.In the Gulf of Mexico, you'd be able to set your clock to RCA's Port Arthur Radio who banged out his "CQ CQ CQ DE WPA WPA WPA TFC LIST QSW 418/HF =" tobeat any TTT CQ from NMG (USCG NOLA which served the entire Gulf.)73DR  Hans Brakob wrote:Mon, Jan 10, 2022 at 12:58:01AM +0000> Maybe so in merchants, but military online crypto systems needed precise time for synchronization with their partners.> > 73, de Hans, KØHB> “Just a Boy and his Radio”™> Master Chief Radioman, US Navy (Ret)> > ________________________________> From: cw-bounces at mailman.qth.net <cw-bounces at mailman.qth.net> on behalf of Richard Knoppow <1oldlens1 at ix.netcom.com>> Sent: Sunday, January 9, 2022 6:34 PM> To: cw at mailman.qth.net> Subject: Re: [CW] Ship Radio Room clock> > Clocks used for navigation purposes must be as accurate as possible but radio room clocks are not used for navigation, only log keeping.> > ______________________________________________________________CW mailing listHome: http://mailman.qth.net/mailman/listinfo/cwHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:CW at mailman.qth.netCW List ARCHIVES: http://mailman.qth.net/pipermail/cw/Unsubcribe send email tocw-unsubscribe at mailman.qth.netSubscribe send email to cw-subscribe at mailman.qth.netSupport this email list: http://www.qsl.net/donate.html=30=
