Assisting with Army Deployment

Last night, I assisted an American Red Cross team in seeing off a group of 1st BCT, 3rd ID soldiers from Fort Stewart off on their deployment to Iraq. Guy McDonald, K4GTM picked me up around 8 PM and we went over to the Truscott terminal at Hunter AAF. The team served coffee, hot chocolate, and tea for the soldiers as they ate a meal, manifested, and prepared for departure. As they boarded the aircraft, the Red Cross team and the USO saw them off with good words of thanks. It was cold and windy last night, but it was a good way to spend an evening.

I brought along my my BC396 and an earphone; it was helpful to be able to listen to Hunter Tower and Base Ops, Hunter Trans Alert, and the DOL folks. Keeping an ear on their radio traffic helped us keep up with what was going on and when things would be happening. I think we were better prepared as a result.

Two things struck me last night. First I was struck by how young many of the these soldiers are. No doubt many of these were on their first deployment (assumed from the lack of unit patches on many left shoulders). I'm not exactly old, but many of these men and women seemed to be just kids. Second, I was struck by just how many female soldiers there were. One of the units on last night's flight was an MP unit and I'll bet the ratio of female to male soliders was close to 50/50. I would be really interested in seeing figures on how the Iraq and Afghanistan wars compare to previous wars and confilicts in the overall ratio of females to males serving.

Godspeed and Best Wishes to all of the Service People that are deployed or are deploying to our many committments overseas.

RESCUE RADIO: GEORGIA HAMS GIVEN $165,000 TO BUILD D-STAR RESCUE RADIO NETWORK

I received this in email this morning and thought it would be good to post here. The Pembroke D-STAR repeaters mentioned are on the WVAN tower in Pembroke and provide mobile but not portable coverage in Savannah.

Its one of the largest government grants ever given to ham radio emergency communications. This as $165,000 in Federal funding has been secured by Georgia Emergency Management Agency to complete a statewide D-Star based ham radio emergency communications network.. Amateur Radio Newslines David Black, KB4KCH, has the story of the grant and the all digital rescue radio network that it will create:

The networks creation is the result of a dream that started in 2005 according to John Davis, WB4QDX. Thats when a vision was born for what amateur radio emergency communications could one day achieve in the state of Georgia. Mark Fehlig, WA6NGC, is the former director of Engineering for the states Public Broadcasting System. When the opportunity arose to install two amateur radio antennas on each of nine television towers providing statewide coverage, Fehlig jumped into action. Fehlig designated Georgias Amateur Radio Emergency Service to control the use of those sites for emergency communications. The next task was to figure out the best technology to use at those sites.

Linked FM repeaters and packet were among the modes considered. But radio amateurs were also watching emerging D-Star technology. They recognized it as a state of the art platform providing simultaneous voice and data communications. Knowing that D-star also allows repeaters to be linked on a flexible basis and that it permits simultaneous voice and low speed data along with high speed Internet connectivity at 1-point-2 Gigahertzand the decision was made to go D-star for the states new system.

When the network is finished, radio amateurs will have access to voice and data repeaters on all nine towers across the state, operating on 2 meters, 440 MHz and 1-point-2 Gigahertz. Because those towers are strategically located to provide maximum public television coverage, amateur radio communications will benefit from wide area coverage, as well. Commercial grade inch and 5/8 transmission lines will connect the antennas, which will be between 500 and 600 feet above ground. Georgias Public Broadcasting Network will provide indoor space for equipment, along with backup power at each site. Internet access will be available, too, thanks to the broadcasting systems DS-3 data networkthis means flexible linking of repeaters will be possible using a stock D-Star interface.

The federal money will also pay for 20 dual-band D-star radios to be installed at EMA offices across the state, along with a portable UHF D-Star repeater available for emergency deployment. In addition, three 1-point-2 Gigahertz D-star radios with laptops for sending data and photos from field locations will also be purchased. The money will also be used to build a robust reflector to serve the states network during emergency conditions and also for general use during non-emergency times.
Two of the emergency networks D-star repeaters are already on the air. One is located at Pembroke, Georgia, near Savannah. The second operates from atop Stone Mountain, serving the Atlanta metro area. The complete Georgia D-star amateur radio emergency communications network is expected to be in operation in early 2010.

For the Amateur Radio Newsline, Im David Black, KB4KCH, at the South-East bureau in Birmingham, Alabama.


The Georgia network will complement other D-Star based emergency communications systems planned or in operation in the neighboring states of Alabama, Florida and South Carolina. Once all are in operation, it will create a regional ham radio emergency capability across the American Southeast. This monetary grant is only second in size to one of $250,000 given by the governor of Oregon in 2007 to that states ham radio first responders. This, to build a Winlink-based state-wide amateur radio emergency communications network. (WB4QDX, Georgia ARES via Southgate) via ARN news

Good FIre Related Twitter Feed: Federalfire

I came across this Twitter Feed tonight: http://twitter.com/Federalfire. If you're interested in keeping up with fire calls in the Savannah area, this is a pretty good Twitter Feed to follow.

USCG Helicopters using Digital Voice and USCG UHF NET Frequencies?

Back in August, I posted an article about the USCG in the Savannah area using CG 113 (163.1375) in P25 digital voice mode for communications as part of the new RESCUE 21 communications system. The last week or so has provided some updates on how the Coast Guard in the Savannah area is using the new frequencies.

Last week, I began hearing MH-65Cs from CGAS Savannah using CG 113 with Sector Charleston and with some of the area USCG boats. I've also heard them request to use CG 111 and CG 112 with Sector Jacksonville. The three digit identifier indicates the use of P25 digital voice and I have heard them use P25 digital voice so this confirms that the helicopters now have radios capable of utilizing P25.

Today, when 6565 departed CGAS Savannah for AirFac Charleston, Sector Charleston asked them to switch to "UHF Channel 410" for guard. I'd never heard reference to that channel so I immediately threw a couple of radios into search mode. In short time, I found Sector Charleston on 413.000 working 6510 in P25 digital voice. 6510 continued to use this frequency for guard radio traffic with Sector Charleston until they landed later at CGAS Savannah. 6565, after initally having no joy on the frequency, began keeping their guard on "CG 410" as well. It seems that in addition to a set of VHF NET (or what the USCG units seem to refer to as "CG") channels, there is also a set of UHF NET (or "CG") channels.

For those that enjoy listening to the Coast Guard, it is definitely a time to begin looking for a digital capable scanner if you don't have one now. It is also time to begin looking beyond the Marine VHF and HF frequencies for both Coast Guard surface and air communications. Just as USCG assets have begun moving away from such old favorites such as 5.696 USB to the COTHEN HF system they are beginning to move away from Marine VHF to the RESCUE 21 system.

Coast Guard Helicopter on NET Channel Using Digital Voice

Location: Savannah

This evening, I was listening to Coast Guard 6545 (MH-65C, Savannah) as it conducted hoist training with 25' boat 25732 in the Savannah River. 25732 requested that 6545 go to NET 113 (163.1375). 6545 then came up on NET 113, calling initially in analog voice before switching to digital voice.

This is the first time I've heard one of the Savannah MH-65s on the NET Channels and the first time I've heard one using Digital Voice. I'm guessing it is being done with a radio separate from the one used for Marine VHF because while they were using NET 113, they were also able to hear and to respond to Station Tybee on Marine VHF Ch. 21.

VMFT-401 at MCAS Beaufort

Location: Savannah

F-5s from VMFT-401 are operating out of MCAS Beaufort this week. They worked in the SEALORD Special Use Areas today using their usual callsign SNIPER and Tac frequencies 268.300 and 285.375. They were also on the SEALORD frequencies 284.500, 376.900, and 385.300 and Beaufort Approach/Departure on 292.125.
