Locator Transmiter- Spring 2003
(Picture Coming Soon)
Small aircraft use a devise, called an ELT, that transmits
on 121.500Mhz AM when triggered by a large amount G-Force's.
I modified an ELT to transmit on 121.775Mhz which is the
practice frequency. I will use it with Yamhill County ARES
to help practice searching for downed aircraft. I also built
it into a new metal case to help with shielding. The older
one had batteries epoxyed in and anything that could be
used to disolve the epoxy would have disolved the plastic
case it was in. I also installed a 12V Sealed Lead Acid
battery that lasts several days of continuous operation.
For an antenna, I built a Tape Measure Beam for hunting
while on foot and a quad for hunting when in a car. I'm
also going to build two yagi's to make an interferometer
which is acurate to within 1 compass degree.
