Silence Period and Horlogery[edit]

First off, I got to this page through the horlogery category listing. I don't know if that's correct. Though the i believe the 2182kHz may refer to a "tick number", the number of repeated movements a watch makes per hour. Secondly, the article talks about a mandatory silence period but fails to mention why this is so.
Other than that I learned something new again :) --Jimius (talk) 11:05, 8 March 2009 (UTC)

I've added a sentence to explain the 'why'. Thanks for a good point - it may have been obvious to the original author, but if it's not so to the reader, then we can fix it! --Nigelj (talk) 21:52, 9 March 2009 (UTC)
BTW, "kHz" or "kilocycles" would mean that a quantity is in units of thousand per second, not per hour. 32.768kHz is the standard digital watch crystal, vibrating 32768 or 215 times per second. --66.102.80.212 (talk) 22:57, 17 March 2009 (UTC)

RANGE[edit]

In the RANGE section the article states: "At night a well equipped station can achieve INTRA-continental communication", this should be changed to INTER-continental. INTRA means within, INTER means between. An intra-continental communication is restricted to the same continent where the signal opriginated. INTER-continental means between one or more continents. —Preceding unsigned comment added by 207.7.74.74 (talk) 06:18, 9 March 2010 (UTC)

I think it was correct before - intercontinental communications generally requires a range of a few thousand miles. This is possible at frequencies like 14 MHz, but not in the 2 MHz band. Either way, the statement was unclear and uncited, so I have removed it. I left in the bit about lightning and other static as that is definitely true and provides the main limitation on range. It also shows why the range varies from night to night, so that hard-and-fast statements cannot really be made. Similarly for VHF, although high-pressure weather can produce extraordinary effects, the normal reliable range depends mostly on antenna height. --Nigelj (talk) 17:56, 9 March 2010 (UTC)

Licensing[edit]

This section states: "In order to operate a marine radio transceiver on 2182 kHz, the operator must hold a GMDSS General Operating Certificate". this is incorrect. While a GMDSS Operator can operate a radio on 2182 KHz, this is not the only class of commercial operator authority. GROL, MROP, and the holders of Radiotelegraph license holders can also operate 2182 KHz radios.207.7.74.74 (talk) 06:49, 9 March 2010 (UTC)

This is probably a good point. Do you have a reference that confirms what you are saying? If so, please leave the URL here so we can have a look and adjust the wording accordingly. In the meantime, I'll try and squeeze "or equivalent" or some such wording into the article. --Nigelj (talk) 18:01, 9 March 2010 (UTC)
