VHF DSC Radio Check
"Larry" wrote in message ... "claus" wrote in : Any ideas or suggestions on how to check the DSC funtionality? By the way....before you make an issue out of CG's lack of DSC operation, it might be a good idea to get your GMDSS Operator's License, which is actually REQUIRED before operating a VHF DSC on Channel 70 in the FCC regulations......(c; Here's the regs: http://www.access.gpo.gov/nara/cfr/w...7cfr80_07.html Here's what a NON-LICENSED boat VHF radio is allowed: Section 80.13 (c): " (c) A ship station is licensed by rule and does not need an individual license issued by the FCC if the ship station is not subject to the radio equipment carriage requirements of any statute, treaty or agreement to which the United States is signatory, the ship station does not travel to foreign ports, and the ship station does not make international communications. A ship station licensed by rule is authorized to transmit radio signals using a marine radio operating in the 156-162 MHz band, any type of AIS, any type of EPIRB, and any type of radar installation. All other transmissions must be authorized under a ship station license. Even though an individual license is not required, a ship station licensed by rule must be operated in accordance with all applicable operating requirements, procedures, and technical specifications found in this part." Notice, CAREFULLY, what signals are allowed....Marine Radio (voice?) in the 156-162 Mhz band, any type AIS, any type EPIRB and any type RADAR. "All other transmissions must be authorized under a SHIP STATION LICENSE".....INCLUDING GMDSS AND DSC data transmissions on Channel 70?? NOTHING is said about DSC or GMDSS, which your MMSI and DSC equipment on VHF are a part of.....It's a kluged up mess! HOWEVER, in the GMDSS section of the rules, it says: "PART 80_STATIONS IN THE MARITIME SERVICES--Table of Contents Subpart W_Global Maritime Distress and Safety System (GMDSS) Sec. 80.1073 Radio operator requirements for ship stations. (a) Ships must carry at least two persons holding GMDSS Radio Operator's Licenses as specified in Sec. 13.2 of this chapter for distress and safety radio communications purposes. The GMDSS Radio Operator's License qualifies personnel as GMDSS radio operator for the purposes of operating GMDSS radio installation, including basic equipment adjustments as denoted in knowledge requirements specified in Sec. 13.21 of this chapter. (1) A qualified GMDSS radio operator must be designated to have primary responsibility for radiocommunications during distress incidents, except if the vessel operates exclusively within twenty nautical miles of shore, in which case a qualified restricted radio operator may be so designated. (2) A second qualified GMDSS radio operator must be designated as backup for distress and safety radiocommunications, except if the vessel operates exclusively within twenty nautical miles of shore, in which case a qualified restricted GMDSS radio operator may be so designated. (b) A qualified GMDSS radio operator, and a qualified backup, as specified in paragraph (a) of this section must be: (1) Available to act as the dedicated radio operator in cases of distress as described in Sec. 80.1109(a); (2) Designated to perform as part of normal routine each of the applicable communications described in Sec. 80.1109(b); (3) Responsible for selecting HF DSC guard channels and receiving scheduled maritime safety information broadcasts; (4) Designated to perform communications described in Sec. 80.1109(c); (5) Responsible for ensuring that the watches required by Sec. 80.1123 are properly maintained; and (6) Responsible for ensuring that the ship's navigation position is entered into all installed DSC equipment, either automatically through a connected or integral navigation receiver, or manually at least every four hours when the ship is underway." See what a mess it all is? Typical Doublespeak......lawyers. 80.1073 (b)(6)----RIGHT THERE AT THE BOTTOM....is the key..... A qualified GMDSS Radio Operator, and a qualified backup, as specified in (a) MUST be: (6) Responsible for ensuring the the ship's navigation position is entered into all installed DSC equipment, either AUTOMATICALLY THROUGH A CONNECTED OR INTEGRAL NAVIGATION RECEIVER (GPS) or manually at least every 4 hours when the ship is undeway." This section says you are REQUIRED to have a LICENSED GMDSS OPERATOR who is responsible to see that DSC in your little VHF radio has the proper position, even if your Garmin hand held is plugged into the little West Marine VHF feeding it automatically lat/long......REQUIRED OPERATOR....FOR DSC....no exceptions. So, which GMDSS OPERATOR license do you need?? " (1) A qualified GMDSS radio operator must be designated to have primary responsibility for radiocommunications during distress incidents, except if the vessel operates exclusively within twenty nautical miles of shore, in which case a qualified restricted radio operator may be so designated. (2) A second qualified GMDSS radio operator must be designated as backup for distress and safety radiocommunications, except if the vessel operates exclusively within twenty nautical miles of shore, in which case a qualified restricted GMDSS radio operator may be so designated." depends on if you go more or less than 20 miles offshore..... NOTE - IF YOU GO 3 MILES OFFSHORE YOU ARE ALEADY REQUIRED TO HAVE A SHIP STATION LICENSE FOR THAT VHF as that is in international waters....3 miles. http://wireless.fcc.gov/commoperators/do.html GMDSS Operator's License.....just the operator who is allowed to make front panel adjustments like putting MMSI in and calling distress. http://wireless.fcc.gov/commoperators/rg.html If you never venture beyond 20 miles out from the USA shoreline..... ANY operation of DSC on a pleasure boat in or out of US waters requires a SHIP STATION LICENSE and at least a primary and backup GMDSS Operator's Licensed operator...inside or outside that 20 mile limit. More noise...... http://wireless.fcc.gov/services/ind...b=operations_2 &id=ship_stations http://wireless.fcc.gov/services/ind...b=operations_2 &id=ship_stations#What%20are%20the%20requirements% 20regarding% 20communications%20personnel%20aboard%20GMDSS%20sh ips? http://wireless.fcc.gov/services/ind...b=operations_3 &id=ship_stations GMDSS operations has NO EXEMPTIONS FOR UNLICENSED VHF STATIONS I can find.....nada. Just pressing the red button isn't enough....ask the FCC..... GREAT SCOTT!!! |
