Viele Yachten auf großer Fahrt rüsten sich inzwischen mit einer
Kurzwellenanlage aus, was für die Kommunikation und Sicherheit an Bord
unerläßlich ist. Viele Segler aber haben wenig Infos über den sachgerechten
Umgang mit ihrem Gerät, vor allem wissen sie nicht, welche Frequenzbereiche
für den Seefunkverkehr benutzt werden dürfen. CHUCK von der SY TAKES ME AWAY
hat dieses Problem aufgegriffen und eine für uns alle interessante
Zusammenstellung gemacht: The following is an update to the Marine SSB radio discussion notes which I previously sent you. If you desire a complete copy of any of the 3 messages or all of them please email chuck@nagle.com. Thanks to the many cruisers who have provided valuable feedback & additions. If anyone receives duplicate copies of this message please reply immediately. I apologize if any PocketMail user had the bottom portion of a message missing on parts 2 & 3. If so I can send it again remidied. If anyone else would like a complete copy, please ask them to email chuck@nagle.com. IMPORTANT NOTICE TO CRUISERS All US Coast Guard groups including San Juan, Puerto Rico respond on 2182.0 USB (J3E) mode only (no longer AM). The USCG has transitioned from AM to USB (J3E) therefore a vessel calling on AM will be heard but the vessel will not hear the USCG. This was by international agreement, however I HAVE NOT verified any other countries. Any marine SSB radio purchased more than 2 years ago will almost certainly have the 2182 Khz button programmed for the now incorrect mode. Icom & JRC marine SSB radios currently being shipped may still have the "2182 Khz" buttom programmed from the factory for the incorrect AM mode. A side note here. During my testing of this issue I contacted the USCG on 2182 Mhz USB using my call sign only. When I did not reply they were able to determine the boat name & description from the EPIRB registration & hailed me on 8104 at 08:00 the following morning I have the commended the USCG via email. SSB INFORMATION PART 2 CHANGES. The US Coast Guard uses 2670.0 Mhz USB as a working channel & you may be asked to switch there after contact on 2182 Mhz. All Venezuela.Coast Guard stations although unconventional monitor the following. 8582.0 Mhz LSB (lower side band). 6355.0 Mhz LSB (lower side band). The Maritime Mobile Service Net is active from 08:00 to 22:00 AST. The Scandanavian net has changed. 8182.0 Khz USB at 08:00 AST & 16534.0 Khz USB at 09:00 AST. SSB INFORMATION PART 3 CHANGES. The "Takes Me Away" emergency distress/hailing order position 2 has been changed from 2182.0 Mhz AM to 2670.0 Mhz USB. ADDITIONAL INFORMATION "Mariners Guide to Single Side Band Radio" by Fred Graves is a good book & is available from Blue Waters Books. I have prepared another document which describes what is involved in using a SSB for email that I can email. I also have a document with the results of my investigation of EPIRB battery replacement intervals that I can email. The USCG web pages that have been unavailable for many months should be available again next week. I am now back in Minnesota therefore standing by as chuck@nagle.com. |
