President’s Report

Our next business meeting will be held in the back room of the Checker Board Restaurant on Saturday August 13th, 2011 beginning at 9:30 AM. Immediately following the meeting, Mr. David Sharp from L.E.M.A. (Lauderdale Emergency Management Agency) will be here to give a talk on the roll amateur radio operators can play during an emergency. I hope we will have a good turnout. Please note the new time of 9:30. We are trying the new time to see if this will attract more attendees.

Thank you to all of the local Volunteer Examiners for the fine job you are doing. Congratulations to all the newly licensed operators and upgrades. See more about these below. Please also note newly issued call sign for Debbie Swiger - KF5MEG. If you hear these guys and gals on the air, please give them a very warm welcome. Have a good month.

73, Darrell, W5MAV

Field Day In The Wilderness of Mississippi
by AmateurLogic.TV

AmateurLogic.TV Field Day Extravaganza. We've shown you what Field Day is before by visiting the Jackson Amateur Radio Club's events. This year we decided to go it alone. The crew (along with a few friends) set off for the woods to get completely off the grid. Jim also wanted to do some astronomy photography and this location offered lower light pollution. Join us as we setup, operate, and camp out to learn what worked and what didn't. You're bound to enjoy this AmateurLogic take on Field Day. Just under 40 minutes.



The Rig Register

If your radio equipment was stolen could you remember its serial number? Have you recorded it somewhere safe? Would you like to notify people would might potentially purchase it? Have participating shops checking on repairs and 2nd hand purchases?

Sign up to The Rig Register, a free service, and record your amateur radio equipment details in a safe and easy to find place. Your equipment can marked as lost or stolen for others to check.

The Rig Register isn't just for stolen equipment. Groups and clubs can use it as an asset register and a shared login between committee and leaders would allow access to the group's or club's asset list.

APRS or APRS vs. Packet Radio

On Occasion I get questions about APRS or APRS vs. Packet Radio. APRS is short for Automatic Position Reporting System, which was designed by Bob Bruninga, WB4APR, and introduced by him at the 1992 TAPR / ARRL Digital Communications Conference. I am not familiar with APRS so have done some limited research and have found this:

Fundamentally, APRS is a packet communications protocol for disseminating live data to everyone on a network in real time. Its most visual feature is the combination of packet radio with the Global Positioning System (GPS) satellite network, enabling radio amateurs to automatically display the positions of radio stations and other objects on maps on a PC.

Other features not directly related to position reporting are supported, such as weather station reporting, direction finding and very limited messaging. APRS is different from regular packet in several ways:

 It provides maps and other data displays, for vehicle / personnel location and weather reporting in real time.

 It performs all communications using a one-to-many protocol, so that everyone is updated immediately.

 It uses generic digipeating, with well-known call sign aliases, so that prior knowledge of network topology is not required.

 It supports intelligent digipeating, with call sign substitution to reduce network flooding.

 Using AX.25 UI-frames, it supports two-way messaging and distribution of bulletins and announcements, leading to fast dissemination of text information.

 It supports communications with the Kenwood TH-D7 and TM-D700 radios, which have built-in TNC and APRS firmware.

Conventional packet radio is really useful for passing bulk message traffic from point to point and traditionally can be difficult to apply to real-time events where information has a very short lifetime. APRS turns packet radio into a real-time tactical communications and display system for emergencies and public service applications where messaging is short and expected to be quick and brief.

APRS provides universal connectivity to all stations, but avoids the complexity, time delays and limitations of a connected network. It permits any number of stations to exchange data just like voice users would on a voice net. Any station that has information to contribute simply sends it and all stations receive it and log it.

APRS recognizes that one of the greatest real-time needs at any special event or emergency is the tracking of key assets. Where is the marathon leader? Where are the emergency vehicles? What's the weather at various points in the county? Where are the power lines down? Where is the head of the parade? Where is the mobile ATV camera? Where is the storm?

To address these questions, APRS provides a fully featured automatic vehicle location and status reporting system. It can be used over any two-way radio system including amateur radio, marine band, and cellular phone. There is even an international live APRS tracking network on the Internet.
