Greetings Murray:

I apologize for taking so long to respond. Although I do not personally know of anyone that can assist you in your endeavor, you might be able to enlist a willing participant by posting this message on one or more of the RF Cafe Forums (index.htm). There has been a fair amount of activity there, so there is a good chance that you will at least get some curious inquisitors. Thanks for writing.


Sincerely,
Kirt Blattenberger

Hi Kirt:

My son and are members of the USAF Aux. (Civil Air Patrol) and I am in the software business (AI) so I am familiar with advances in technology assisting sucess. We ar very active members of the Ground Teams that go out and locate downed aircraft, we actually worked the Columbia Shuttle recovery in Texas.

I was stunned by the lack of technology in this area and prevailed upon an old friend in Japan to create a modified DF ( fox hunting) device to assist in the location of ELTs that have tripped the satellite network for rescue. The company in Japan has closed their doors and I only have one unit, I am looking for some assistance in finding a RF engineer to re-engineer the product. I am trying to keep this at a low cost because it is a volunteer organization, I was hoping for someone who might also be a pilot and would understand the need for this project. I am funding this out of my own pocket but am trying to minimize the development costs. Anyway anything you could do to point me in the right direction would be great.

Thanks you

Murray Craig

Murray-
I would suggest you contact the amateur radio community in your area. Many local groups get involved in transmitter hunting contests, and have developed the antennas and methods to do it efficiently. Also, many amateur radio enthusiasts are pilots.

I have done few units working up to 7 miles. Try the directional finding systems for falconry. They are somewhere in Illinois, Wisconsin.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
