Next Topic: VHF DSC
16
VHF DSC: Intro
VHF DSC = Very High Frequency, Digital Selective Calling
Summary: DSC is a digital mechanism for quickly calling a DSC
radio or group of radios, which also allows exchanging digital info like Boat Name and GPS position. DSC can send an emergency call in about 1/3 second. DSC uses Channel 70 for digital traffic.
17
VHF DSC: MMSI Considerations
MMSI = Maritime Mobile Service Identity, free for boats in USAonly locations from www.boatus.com/mmsi
Otherwise register with the FCC for $160 if your boat might travel out of the country
The MMSI is the unique ID number for your device
If multiple devices onboard, all can have same MMSI But the MMSI should probably stay with the device when its sold
(and the MMSI registration info cancelled), or the device will probably have to be sent back to the factory for MMSI reprogramming
The MMSI registration can include
Boat Name, Boat Type, Boat Size, How Many People Might Be Onboard, Home Port, Home Address ...
... Cell Phone numbers, Home Phone Numbers, Phone Numbers of Other People Who May Know Your Boating Plans
18
VHF DSC: Setup Considerations, Part 1
Register for an MMSI Program your device with your MMSI number Program your device with your boat name Connect to your GPS make sure it displays your location info
An emergency call will digitally send MMSI, Boat Name and GPS data Connect to your VHF antenna make sure you can recv/send Read your device instructions so you know how to use it before an
emergency
It is important to do all the above steps. Even after
5 years of DSC operation via Rescue 21, the USCG reports only a small percentage of emergency calls are DSC with GPS location data. Once you've done all above, you can program the MMSI numbers of your friends into your radio.
Note: Channel 70 is not available for voice traffic because it is dedicated to DSC data traffic.
19
VHF DSC: Setup Considerations, Part 2
Important: Most radios will not transmit anything if you hold down the red emergency button but there is no MMIS number programmed
20
VHF DSC: Intro To How It Works for a Private Call
Before DSC, example
Voice call on VHF 09, "Calling Blue Horizon, calling Blue Horizon, calling Blue Horizon, this is Fun Sway, over"
"Fun Sway this is Blue Horizon, over" ***
"Blue Horizon, please switch to 08", over.
"Blue Horizon switching to 08, over"
On 08: "Fun Sway this is Blue Horizon on 08, over"
With DSC, example
DSC call from Fun Sway to Blue Horizon includes request to switch to 08, is created by a couple/few menu selections and is sent in 3 seconds or less. The call is not recognized by anyone else.
Caller (Fun Sway) is notified via DSC that the called radio has acknowledged the call (some DSC radios acknowledge the request but there may be no one operating the radio)
On 08, normal voice call response: "Fun Sway this is Blue Horizon on 08, over" ***
*** At this point, you know the called boat is willing to talk to the caller.
Nice Benefit: You can be called regardless of which channel you are on.
21
VHF DSC: Can also be used to start a Group Call
Group MMSI #s can be created, for example:
SBCC All Radios Group SBCC Cruise Group SBCC Racing Group
Then a caller could send a DSC broadcast requesting all radios in the group switch to the working channel selected by the caller
Group MMSI numbers are not registered, but are created locally by the users/groups
22
VHF DSC: Demonstration Parts List
Handheld #1 m/v "Fun Sway" dinghy Fixed Mount, full DSC Class D s/v "Fun Sway" Handheld #2 s/v "Blue Horizon" AIS Transceiver: used only to provide GPS data to the Fixed Mount radio
23
VHF DSC: Using the radio controls
Notice the radios have buttons for CALL, ENT (enter/select), CLR (clear/exit) and up/down menu navigation
CALL/ENT key is combined on the handheld (black background)

VHF DSC: Demo, Part 5 of 5
Notice what happens when the called radio is turned off

33
VHF DSC: Purchasing Considerations (Fixed Mount, for DSC features)
As of March 2011, fixed mount VHF DSC radios sold as new in the USA must be at least "Class D" compliant
That means they must have a radio receiver dedicated to DSC on channel 70
There are some other functional changes from being "SC101" or "SC-101" DSC compliant to being "Class D", the most important of which is not automatically switching to a requested working channel until acknowledged via a button push (avoids automatically switching away from a drawbridge conversation on CH 13, for example).
34
VHF DSC: Purchasing Considerations (Fixed Mount, for other features)
Other fixed mount VHF DSC considerations:
Physical size: Will it fit without modification to mounting space? Need it to be waterproof? GPS connectivity: compatible with existing GPS? NMEA 0183? 4800
baud? What GPS `sentences' are needed for full feature set? AIS connectivity: compatible with desired AIS device? 38400 baud? Note: may need an external interface device to translate info with
existing GPS and/or AIS Do you need a remote mic? With full or limited features? What
distance from base to remote? Want to be able to use remote mic as intercom with base unit? Note: Wireless remote mics will have battery limitations which will be problematic on long trips. Want automated fog horn to an external speaker? Any features disabled while using automated fog horn? Want pager to external speaker? Want two-way (can use external pager horn as a microphone)?
35
VHF DSC: My Purchase Criteria (Fixed Mount)
In late 2011, I needed to replace my fixed mount VHF radio. Here are the features I needed, in order of importance to me:
Wired remote mic 20-25 feet away from base with full remote control of base station, displaying all info
DSC Class D (full capabilities) Compatible with (or includes) AIS receiver, capable of receiving both AIS
Class A and Class B AIS at the same time. Bonus points if AIS receiver is included in the radio. Able to display AIS information on base station and/or on remote mic (because my older chart plotter cannot display AIS info)
As of end of December 2011, only one solution could do all that at a reasonable price: The Standard Horizon Matrix AIS+ GX2150, including the remote mic RAM3 (CMP30), for about $500
Includes built-in AIS receiver which is compatible with an optional external AIS transceiver
Needs connection to external GPS
36
VHF DSC: Purchasing Considerations (handheld)
Handheld VHF DSC:
As of the end of 2011, there were no handheld VHF DSC radios that are Class D compliant
Consider getting one that is waterproof and floats
Get GPS integrated (inside the radio)
GPS uses more battery power, though
Consider getting a spare battery pack for AA batteries
The handheld should be your backup radio, not primary
25 watts on fixed mount vs 5-6 watts on handheld
Capability: handheld = 1+ miles; fixed mount = 6+ miles
If you don't own one, it's worth buying one for your personal safety
If it's clipped to your belt and you fall overboard, a push of the
switch can start your rescue immediately even if you don't
know your current position, your GPS will.
37
VHF DSC important: Only declare an emergency if it is!
USCG timestamps & records all transmissions for legal evidence
UNDER NO CIRCUMSTANCES SHALL A DSC DISTRESS ALERT BE SENT TO TEST YOUR
RADIO. IT IS A VIOLATION OF THE FCC RULES AND CAN RESULT IN HEAVY FINES.
You can make a DSC test call with a friend
38
VHF DSC: Making an emergency call
Lift the spring-loaded latch that covers the red button Approach #1, if you have time: Briefly press the red button, select your emergency
type (for example "Taking on Water") then hold down the red button for 3 seconds Approach #2, if you need to quickly abandon ship: Just hold down the red button for
3 seconds Your details are broadcast and received in about 1/3 second (if in range) Your emergency call is automatically repeated by the radio until it is electronically
acknowledged by the rescuer, at which point your radio stops the emergency transmission You should still do a normal emergency call on 16 with your voice: Mayday! With the emergency call acknowledged, your radio is moved to CH 16 where the USCG can try to contact you via radio
The USCG immediately knows your Boat Name and where you are (GPS) From your MMSI registration, the USCG knows who you are, more info on your boat, and
how to call your home phone, cell phone, etc
Note: Read your instruction manual for correct details.
39
VHF DSC: Receiving an emergency call
All nearby DSC radios are switched to channel 16 by the call You should stay on channel 16 until the emergency is resolved, in
case you can help You should save the location of the distressed vessel as a
waypoint You may need to relay details to the rescuers If you can assist, notify the USCG and vessel in distress
If possible, navigate to the waypoint to assist
40
VHF DSC: Relays Might Extend Your Range but don't expect this
Some DSC radios can relay an emergency call probably manually (circles are suggesting the range of the radios)

Add a new Masthead section?
Do a test DSC call with a friend
43
VHF DSC: Reasons to Own It (Conclusion)
In an emergency, DSC can electronically notify Coast Guard AND ALL NEARBY RADIOS in about 1/3 second with:
your GPS location, nature of distress, boat name
Via MMSI, the USCG can look up your home and cell phone numbers to get your name and contact you via phone
All boats within range are switched to channel 16
Enables sharing GPS location information quickly with a friend, so you can find each other accurately
Can even automatically poll another DSC radio to follow its path
DSC is the fastest way to call someone and switch to a working channel
You might use DSC to locate your stolen boat, if in range
In a coastal cruising emergency, a VHF DSC connected to a
working GPS is the most valuable device you can have.

Next Topic: AIS
52
AIS: Summary
AIS = Automatic Identification System
Summary: AIS is a digital mechanism for receiving and/or sending
information AIS transmissions periodically send data on location,
direction, speed, ship name, MMSI and other details A good AIS receiver does calculations to determine if a
nearby vessel is a threat of possible collision, and then sounds a warning signal for you.
53
AIS: Onsite Parts List (Screen shots will be used for demo)
AIS Transceiver Also provides GPS data to Fixed Mount VHF Fixed Mount VHF Radio with AIS Receiver and Display s/v "Fun Sway" Antenna active sharing device Allows AIS transceiver to share antenna with VHF radio PC-based software connected to AIS transceiver via USB/RS-232 Converter

The other vessel is seen "around the corner" by AIS before being in sight visually or on RADAR
Notice how CPA in the top row goes down to 0.01nm before Doug alters course
64
AIS: Reasons to Own It, Part 1
If you travel outside of the Great South Bay, you will probably come near many commercial vessels
If you need to be SOLAS compliant for an offshore race you will be required to have a Class A transmitter (12.5 watts) working on board while underway
Recreational vessels can optionally have a Class B transmitter (2 watts)
AIS displays info on nearby large commercial vessels (and other vessels with an AIS transmitter), so you can
Determine if they are a threat; if you need to change course/speed
Contact the specific vessel by name or MMSI
65
AIS: Reasons to Own It (Conclusion)
AIS is a good addition to RADAR:
Consumes much less power with periodic transmissions (Class B: 2W or Class A: 12.5W)
Provides much more detail and accuracy Can "see around corners" when RADAR is blocked by an object Will work better than RADAR MARPA in rough seas (GPS antenna is lower so
position is more stable)
But AIS transmission is only required on large commercial vessels and on large passenger ships
Is not required on recreational boats Is not required on most commercial fishing vessels
AIS is most useful when away from a busy harbor and in open water
More difficult to use when vessels are right nearby as in NY Harbor, East River, etc.
AIS is supported on many marine navigation chartplotters and software, even iPhone/iPad
AIS might help locate your stolen vessel, if in range

Next Topic: WiFi Repeater
68
WiFi Repeater: Intro
Wi-Fi or WiFi is a name, not an acronym
Summary: WiFi defines wireless network connectivity
standards WiFi normal range is 65 - 300 feet
69
WiFi Repeater: Alternatives,
If you want Internet connectivity on board
#1: Cellular Data
#2: WiFi Repeater
Available up to 2-3 miles
Up to 5 miles is possible
Has usage limitations (ex: 250MB or 2GB / mo); additional charges applied if over the limit
Normal speed ranges from 25Kbps (slow) to 6Mbps (fast); May reduce your speed if you are a heavy user
Might support only one device, unless you can set up a WiFi hot spot
Is best solution while underway & is easiest to set up and use
No usage charges or limitations
Speeds range from 1Mbps (reasonable) to 54Mbps (very fast)
Can support many devices via a WiFi hot spot Best to use while at anchorage or marina & requires some set up 70
WiFi Repeater: MiFi Cellular alternative, from Verizon
One small device: Connects to Cellular Data and creates a local WiFi hot spot for up to 5 devices
71
WiFi: Demonstration Parts List
8 dBi WiFi Antenna (about 6x gain over simple antenna) WiFi transceiver, model name "Bullet" Capable of 1000mw max (10x normal) transmit Ultra sensitive receiver Wireless router from Linksys Sets up a local WiFi "hot spot" for multiple devices Cabling Connects the devices
72
WiFi: Demonstration "Bullet" sensitivity sees more networks
more than 38 seen by "Bullet" -> 15 seen by laptop (below)
73
WiFi Demonstration: WiFi system's fast connection
Notice 36Mbps send, 54Mbps receive to a location about 2000 ft from my inside home
74
WiFi: Purchasing Considerations
Make sure all devices work on 12VDC power
No power loss from power conversion to/from 110VAC Nice to have same power plug and polarity on all
devices
My configuration costs about $330
You can do the math to figure at what point do you get a `Return on Investment' from this, compared to your cellular data usage
75
WiFi Repeater: Reasons to Own It
If you are an active user of Internet connectivity, your need for cellular data services can be reduced and sometimes eliminated by a WiFi Repeater
It has a low power consumption, but is capable of making a WiFi connection of up to 5 miles (more often 2-3 miles)
Optional WiFi hot spot router in your boat can enable connectivity for many devices at the same time
The stronger signal of the WiFi repeater will get faster connection speeds
I got 36Mbps connections at Oak Island Lead and Coast Guard Cove, but no connection at Hemlock Cove at that time
Cablevision clients get access to their free WiFi hot spots
76
WiFi Repeater: Usage Considerations
Very important: When you connect to a free WiFi hot spot, your connection is probably insecure
Do not give a username/password pair to a website unless the start of the address is https://
Email should be done via Secure Sockets (ask your email provider)
Your WiFi hot spot(s) should be set up securely with WPA2 or better
It is best to set up your WiFi hot spot to be 5 WiFi channels apart from the "Bullet"
Like Bullet= Ch 01, hot spot= Ch 06 But the Bullet may change each time as it connects
77
WiFi Repeater: Summary (Conclusion)
If you want easy Internet connectivity onboard, use a cellular network solution and pay the usage charges
And it's available in almost all coastal locations
If you want a faster free Internet connection AND you're willing to do the manual configuration steps, consider a WiFi repeater
But it's not available in all coastal locations

Next Topic: LED Masthead Light
80
LED Masthead Light Purchasing Considerations
Demo unit includes 4 options: (1) all-around white anchor light with (2) photo diode for auto-on/off in evening/morning, (3) tri-color navigation lights and (4) a strobe light for signaling
You can order all 4 options, any combination of 2 options or just 1 option
This unit requires 3 wires, the model without the strobe uses 2 wires
Considerations:
You probably should get all the options, rather than need to go up the mast again someday
The recommendation is to add masthead navigation lights for ocean travel, rather than replace deck-level navigation lights which are important for boats on the bay
Some folks would rather not have the photo diode option (low power draw when on)
When ordering, get the mounting bracket and control switch that fits your needs
My masthead navigation lights also provide night time illumination for my wind indicator
Buy LED lights that have voltage regulators built in
Enables constant light output and longer life
81
LED Masthead Light: Demo (Unit is upside down on white paper)
Tri color
Anchor white
82
LED Masthead Light: (Conclusion) Reasons to Own It
Significant reduction in power consumption
LEDs draw 3.6 watts (0.3A) vs normal bulb draws 10-25 watts (0.8A2.1A)
After 8 hours the savings is 4 amp-hours to 14.3AH
LEDs will probably never need to be replaced in our lifetimes (less mast climbing!)
50,000 hour useful life for operation
LEDs have constant light output over varying voltage and over their lifetime
LEDs do not dim as the voltage drops, do not dim as the LEDs get older and they do not `yellow' over time
LEDs can be run on 9-28VDC
Masthead navigation lights significantly increase visibility to large commercial vessels
Strobe is helpful for signaling
