Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

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

Subject: Civil Air
Patrol Df unit
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.

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.
