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 World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Civil Air Patrol Df unit - assistance needed - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including 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 writing.

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.
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

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