Rescue at Sea
Pacific Ocean: Three 14.300 MHz Amateur Radio 'Networks' respond to an urgent 'PAN PAN' call for emergency assistance from David KF7GWI, one of five crewmen aboard the (36) foot recreational vessel, “S/V Wind Child”, enroute to the Marquesas Islands.
April 3, 2010 by Rex J. Weinheimer KC5AGO, Stonewall, Texas
The Intercontinental Traffic Network (INTERCON), the Maritime Mobile Service Network (MMSN), and the Pacific Seafarers Network (PACSEA) are three volunteer amateur radio “Networks” which sequentially conduct radio watches for up to eighteen hours per day, 365 days per year on HF 14.300 MHz USB; the HF radio frequency now designated world-wide as a “Center of Activity” for emergency communications in the 20 Meter Amateur Radio Band by the International Amateur Radio Union, Regions I, II, and III.
At approximately 10:09 AM EDT, on Thursday 04/01/2010 David KF7GWI amateur radio operator aboard the S/V Wind Child transmitted a “PAN PAN” on 14.300 MHz. The call was heard by “Network” member Bill KI4MMZ of Flagler Beach, FL. Immediately KI4MMZ established contact with KF7GWI and determined the vessels position as being in the Pacific Ocean at (09°-30’N x 126°-47’W), approximately 1,400 miles SW of San Diego, CA. KF7GWI reported a medical emergency with request for immediate assistance. At 12:45 UTC, a 57 y/o male crewmember had sustained a traumatic injury; an internal and external crushing to his throat, extreme laceration to the tongue, and a deep puncture wound to the back of the skull. The patient lost consciousness and had ceased respirations for a period. KI4MMZ quickly established a telephone patch with USCG Sector Alameda, CA and reported the details of the incident.
Within a matter of minutes, USCG Sector Alameda had a Flight Surgeon on the telephone with KI4MMZ. The Flight Surgeon remotely assessed the patient’s condition, asking pertinent questions and receiving responses as passed thru amateur radio “Network” relays with KF7GWI responding from S/V Wind Child.
The USCG determined that a Med-Evac Mission was necessary and swiftly set into motion a very complex plan to rescue the injured crewman and deliver him to a medical facility for treatment as soon as possible. The rescue event is ongoing and hopefully will be successfully concluded by Sunday night.
The amateur radio “Networks” established and maintained a recurring hourly communication schedule with the S/V Wind Child. Amateur radio operators from the “Networks” continued to procure the orderly flow of updated patient information and timely position reports which in turn were passed to the USCG and Flight Surgeon via telephone so that last minute plans could be adjusted.
The USCG and California Air National Guard, jointly communicating with the assistance of “Network” amateur radio operators providing the long-distance communications link to the S/V Wind Child, were successful in delivering the four Para-Jumpers, along with their inflatable boat, rescue, and survival gear to the S/V Wind Child. Per the “AMVERS” alert issued by the USCG, HF radio contact had earlier been established by “Network” radio operators with the M/V Cap Palmerston which had diverted her course and was headed to the S/V Wind Child to assist in the rescue.
The “Network’s” hourly communication schedules were downgraded to a “listening watch” after the fact was made known that the Para-Jumpers were successfully aboard the S/V Wind Child.
The patient and the four Para-Jumpers were successfully transferred to the M/V Cap Palmerston. The ship is currently headed to San Diego. On Easter Sunday, the M/V Cap Palmerston will rendezvous with a task group of (2) MH-130 Hercules fixed-wing tankers and (2) HH-60 Hawk helicopters approximately 500NM west of San Diego, CA.
The helicopters will pick-up the patient and the four Para-Jumpers, and then transport the patient back to San Diego, CA for further medical treatment.
We heartily applaud the professional efforts of the USCG, the Para-Jumpers, the California Air National Guard, the M/V Cap Palmerston, and the many amateur radio operators that assisted in, or stood silently ready to assist in this seamless and successful, combined agency rescue at sea. Kudos for David KF7GWI whom as late as January 5, 2010 received his amateur radio license especially for this voyage of S/V Wind Child; “David felt one person on board should have a license for just such an eventuality!”
Oh yes, one last note of interest, Satellite Telephone service was unobtainable at the scene of the incident.

Re: Time to upgrade to General
The system works.
That is one of many stories showing the benefits of an amateur radio license in emergency situations. From the tsunamis in Indonesia, to the 8.3 quake in Chile, to maritime rescues such as the one DaveK posted, amateur radio has a long, storied history of public assistance in times of need. I'm proud to be associated with a service that can do so much, and asks so little in return.
I think that we at OAUSA are doing our part to dispel some of the "stigma" attached to some people's view of ham radio; in the way we utilize it for communications in the field, to our sponsorship of testing sessions (including this Saturday at HRO San Diego
), to our use of more progressive amateur radio technology including APRS, AirMail, etc...It's not "your father's" radio service anymore, but a relevant means of communication and assistance worldwide, 24/7, and I hope our list of licensees continues to grow.

I bought the iPhone study app for the General test. It’s much more technical than the Tech test. I think I may have to read the book this time.

Re: Time to upgrade to General
Great story!
This is exactly why I got my license and why I am studying now for my upgrade to General.

Re: Time to upgrade to General
Yep, I read this over on the Zed. Kewl story and another great testimonial. If you guys haven't listened to the Maritime Mobile or Pacific Seafarer nets on 14.300....you should. It's not real exciting stuff, but there are some top-drawer operators dedicating their time to this cause.
Oddly enough, despite all the internet technologies being grafted on in order to add fun, luxury and give the hobby a broader appeal, it's usually the basic components of "your father's" radio service and it's simple methods that end up saving the day...just as in this case. HF forms the backbone that supports all independent distance communications within the amateur service...whether SSB or digital.
Some of the similarities between marine mobile and overland mobile should be obvious. Neither has to venture very far to reach a point where other means of communication become completely useless. Could you imagine what the outcome of this situation might have been if the boat were only equipped with a simple marine VHF radio?? This would rarely happen in the maritime community. But, in the offroad community it happens all the time. The CB's and 2m radios are our equivalent to the mariners coastal VHF radios. They are all great tools if you play close to home...but, if you want to make the long crossing or venture beyond the tether of the repeaters....to play smart, you either need to get the General license and become HF capable or get a Satphone.

Yeah, good point...it makes ya' wonder what service they were using. Again, this is a great testimony to the capabilities of HF and HF SSB nets.OLLIE wrote:It would appear that in this situation even the Sat Phone failed.xtatik wrote:if you want to make the long crossing or venture beyond the tether of the repeaters....to play smart, you either need to get the General license and become HF capable or get a Satphone.
