5 The Words of ARRL Communications Manager George Hart W1NJM at the Washington State ARRL Hamfest in Yakima, paraphrased JFK s words and asked, Ask not what the ARRL can do for you, Ask what you can do for the ARRL and Amateur Radio.

6 Those Words Still Ring True Today. Many members of the Federal Way Amateur Radio Club, formed an ECRT Team that practices message handling and other drills that keeps our proficiency at a ready state when we are called to operate radios for served agencies in times of need.

39 Message handling comes in many forms. The US Post office delivers messages by manual means to millions of users each day. They physically deliver the messages (in Letter form), contained inside of a wrapper called an envelope.

40 This The envelope wrapper contains: The "From" Part has: The name of the person, followed by the physical street address or location, the city, the State, Zip Code+4 and the Country.

41 The "To" Part has: The name of the person or c/o (care of ), followed by the physical street address or location, the city, the State, Zip Code+4 and the Country.

42 If the US Post office is successful, the Envelope wrapper & its letter/message are delivered to the location and person named on the envelope.

43 If for some unexplained reason, the Envelope does not have a way to be physically delivered to the addressed person, the post office will return the envelope to the sender.

44 They do this by simply reading the senders address in reverse and send it back to: first the country, then the State, then the City, then the Street address location, and lastly to the person that had originally sent the envelope.

45 The previous example explains the way that the US Post Office handles messages that are contained inside of their "wrapper" called an envelope.

46 Another message service of the US Post Office,, comes in the Form of a post card. Here the message is small in content and printed on the outside of the delivery form,,, and is available for many hands to hold and is also visible for all eyes to read.

47 Message Handling by Amateur Radio and the many different available circuits, all follow a very similar pattern that is used by the US Post Office.

48

49 One of the types of message forms comes in the Radiogram (ARRL Radiogram). This Radiogram has a "To" part, the Message part, and the "From" part.

50 One of the types of message forms comes in the Radiogram (ARRL Radiogram). This Radiogram has a "To" part, the Message part, and the "From" part.

51 Someone or a served agency will create a message that needs to be delivered to a different location that is away from the location/place of the message creator.

52

53 This is where Radio and trained Licensed operators are able to provide a message delivery service for people and served agencies.

54 Once a Radiogram is in the hands of a trained licensed operator, the operator has to check it over for addressing and then figure out what radio circuit can best deliver the message to the intended recipient.

55

56 Since all amateur radio transmissions are non-encrypted, most Radiogram messages become like the open post card going through all of the hands and eyes of the US Post Office.

57

58 The modes of delivery can be as simple as using the tenny-runner-lan or putting it into an existing radio net that is already setup and operating. During an emergency, the radio Net, might be the one in the local area that is operational through a repeater.

59 Our repeaters are able to remain operational 24x7 in their current sites and here are some examples.

60 Repeater Sites MHz FM Analog +Phone MHz FM Analog MHz FM Analog Simplex Direct (Talk-Around)

61 147.04MHz & MHz Rptr. Site 312 th & 8 th Ave.

62 147.04MHz & MHz Rptr. Site 312 th & 8 th Ave.

63 146.76MHz Rptr. Site 360 th & 32 nd Ave.

64 146.76MHz Rptr. Site 360 th & 32 nd Ave.

65 Repeater Sites MHz DV + SDD MHz DV + SDD MHz DV + SDD MHz Digital Data Simplex Direct (Talk-Around) Reflector 035C and 035A, 035B

66 MHz Rptr. Site 876 S. 333 rd Street Federal Way, WA MHz DV & DD Rptr. Site 876 S. 333 rd Street Federal Way, WA

67 The FWARC Repeaters Help us service the Greater Federal Way Area. Locally most VHF or UHF analog repeaters might cover area locations out to a range of 25 to 50 miles.

68 Lakehaven EOC Lakehaven Lakota Fire Dept. EOC City Hall EOC St. Francis Hospital Weyerhaeuser EOC

69 All of the different Radio emission types can enhance the ability to handle the messages to far away locations. CW (Morse code) works for far-a-way locations almost anywhere in the world, and so does a good powerful voice station (SSB).

70 Today's VHF and UHF Digital repeater systems not only cover your local areas, but can be linked to other repeater systems to expand your local area network (LAN) of repeater(s) coverage. 146MHz, 440MHz, and 1.2GHz can all be interlinked at will, if you know the linking language.

71 if you know the linking language.

72 if you know the linking language.

73 The Digital repeater systems also have the ability to create a larger network of radio systems and become a wide area network (WAN ).

74 There are many innovations that allow interconnecting to these digital radio systems from computers such as DVAP, access points, and digital hot spots.

75 Most of the Digital Radio systems carry both voice and digital data over their networks. Most Digital Radio networks can carry both voice and data communications at the same time. Older radio systems carry just one communications mode at a time.

76

77 The Radiogram comes in many forms depending on the transmission mode. Many radio networking circuits try to standardize on a similar form factor modeled around the Radiogram developed by the ARRL many years ago when much message traffic was handled on CW mode nets. i.e. RN7 etc.

78 This radiogram Form factor becomes like the post card used by the US post office. It is open for all to handle and view the contents of the message.

79

80 The Radiogram message form has similar needs to that of the post card, in order to get the message delivered.

81 The "To" part, The Message part, The "From" part. There are also the added pieces to the Radiogram that help the Licensed radio operator with the message sending and record-keeping.

82 First is the Date. Typically the date that the message was created.

83 Next the Time. The time in the local time zone. PST, MST, CST, EST. If the message is outbound to a distant foreign land, both the date and time could be entered in Universal Coordinated Time UTC. (sometimes called GMT )

84 Next the Time. The time in the local time zone. PST.

85 When using UTC the time is always expressed in 24 hour format using 4 digits to express exactly the time. 01:30 UTC means 1:30AM in the morning in Greenwich England. Always include the leading or trailing zeros to fill in the place-holder positions so that all operators know exactly what numeral information has been sent.

86 In the Radiogram, there is a box area for the originating station who put the message into the radio system network. (the From part)

87 There is also a box area for routing information to send the message to the receiving station who delivers the message. (the To part)

88 The main message part contains the actual content, full of information from the message creator.

89 The end of the message also contains a check. this is to help the many operators in the delivery circuit and network, make sure that they have received the correct amount of information contained in the message. The Check really helps the radio operators if a radio path or circuit is full of additional noise and interference.

90 The end of the message also contains a check. The Check really helps the radio operators if a radio path or circuit is full of additional noise and interference.

91

92 The US Post office uses similar type of confirmation of delivery in the form of a confirmed delivery receipt. FEDEX and UPS all use tracking numbers for confirmation. In the case of the Radiogram, the confirmation check travels right along with the message KL7BB

93 The Radiogram is assigned a number at the station that originates the message. For simple occasional traffic handling, most any number system seems to work.

94 However if a lot of traffic is handled by many different operators over a longer period of time,,, simple message numbering can become confusing.

95 It can really improve your operation if a message numbering system can have an expectation of three or more numbers used to track what numbered message was sent and/or replied to.

96 If each day a restart of message #1 was used over and over again,,,,how will a different operator at you EOC figure out which #1 message is being referred to.

97 If a three digit system is used, then there is only one number #001 in your system.

98 It is possible that for very active traffic stations that a date number also be included into the message numbering system.

99 # could only mean: the year 2011, the month November and the day 17. Message # 001 This type of numbering becomes very usable when many messages are being handled on a digital radio network.

100 Next the "To" Name. The Name John works, if everyone knows who John is. A better description might be to also include more information such as a last name, or a ham radio call sign. John N7KTJ leaves little doubt as to whom the message is intended.

101 In an ICS and EOC venue, it might also help deliver the message to the right person,,,if the title of the person is known,,, say, maybe John N7KTJ is also the incident commander. So the To part of the message might read To: John N7KTJ incident commander.

102 by adding the titled persons Title, it gives everyone handling and viewing the message an extra sense of responsibility to get this message delivered to the incident commander John N7KTJ. and not just to some ham buddy named John.

103 The same thing also can apply to the From part. When it reads From Skip, who knows what Skip does.

104 When the message reads from Skip P. Mayor of Federal Way, WA. The message takes on a whole new level of importance to all who handle and view the traffic.

105 Telephone numbers also take on a special need. If all that is supplied is ,,, then the area had better be understood, from where that number is going to be dialed from.

106 It is much better for all operators to also have the full phone number of so that the message routing could be dialed from anywhere else in the world to deliver the message.

107 Involvement by the FWARC.org Members City Hall Fire Dept. Lakehaven Utility Dist MHz Repeater on the air. Amateur Radio nets fully operational. 5 th Saturday Drills EOC to EOC

108 Nisqually Earthquake February 2001 Amateur Radio Net became operational. Amateur Radio provided communications to Police, Fire, Gov, Utilities. ( by relaying messages) Live Field reports on city conditions. Reports on surrounding areas.

109 The environment for the FWARC has changed, and people from other Amateur Radio Groups are now asking themselves how can we also perform a service to their community in the times of need.

114 Many times the ham radio bands are only open to someplace far removed from the delivery area,,, and that far-a-way operator ends up being the one to handle the message traffic.
