A less known group of volunteers provide essential communications throughout the race course. A group of IC-4088SR enthusiasts know as B.A.R.C., the Beargrease icom radio Coalition. These dedicated enthusiast's supply all the radio equipment and personnel to man all the check points and road crossings 24 hrs a day throughout the whole race. Many of them are on the radio, tracking the position of every sled and every dog continuously for 24 hours at a time.
It was my job to get the information translated from the interpreter. Then I would make sure it made sense somewhat. Next I'd decide its relevance (if it was pertinent to current operations I would immediately send it up over the radio, type it up and send it over text chat (computers connected over radio communications), otherwise I'd just text chat the written version).
If they are rechargeable, then make sure they have a full charge. If they are disposable, make sure you replace the Marine VHF unit with fresh batteries (as well as stocking your boat with a plethora of backups). Next, turn the icom marine radio on and test out that it is properly functioning to ensure that you can make a SOS call if need be. You cannot be too careful with the above mentioned steps. Many times in our excitement for all of the fun we are going to encounter we tend to overlook the necessary precautions. Please prepare a safety checklist and make sure every item on the list is taken care of before your first trip out of the season.
After you have your trip line aboard, remove it from the anchor crown. Rinse the line in fresh water, dry it well, and coil it back down into your anchor locker.
Supply them with GPS Tracking technology. With the simple use of a Motorola GPS enabled radio you can deploy a mobile tracking solution that keeps you in touch with your aid workers 24/7. Not only can you communicate with them via icom communications (should the local infrastructure allow) but you can also use the integrated GPS transmitters to track positions of the workers at all times.
Bill - The High Altitude Research Corporation does a variety of "Near Space" and space-related research and development for NASA, universities and commercial customers. One of our projects involved launching a rocket from a balloon while over 70,000 feet high.
It would also be a good idea to have a decent set of FRS/GMRS radios for portable short range communications. The GXT1000VP4 and GXT1050VP4 are great options.
