Radio Direction Finding March 13 2011 Sunday

Along the topic of PLB's see thread viewtopic.php?f=24&t=2630&p=23470#p23470

One of the advantages is the ability of these devices to transmit a local tracking signal that can be "sniffed" by rescuers.

This Sunday there will be a Radio Direction Finding session held in Southern California.

Here is the information from the So Cal ARDF group

The weather forecast looks good for our next on-foot direction-finding session
at the Santa Fe Dam Recreation Area on Sunday, March 13. There will be
entry-level two-meter fox transmitters for beginners, a 5-fox two-meter
international-rules course of low to moderate difficulty, and an
antenna/attenuator building workshop. If you want one of Marvin's kits for
antenna and/or attenuator, please send e-mail to right away.

Daylight savings time begins on this day, so set your clocks ahead one hour
Saturday night so you won't be an hour late. Kitbuilding starts promptly at 10
AM, followed by the beginner hunt. The main 5-fox hunt will commence at 10 AM
also. Hunters may start out on the courses at any time until 1 PM. Courses
close at 2:30 PM.

For the advanced 2-meter course, orienteering flags and electronic scoring will
be used at each transmitter. If you have an "e-stick," be sure to bring it.
There will be a $7 donation for the advanced course to cover expenses related to
the use of Los Angeles Orienteering Club's e-punch equipment and maps ($5 for
LAOC members). No donation is requested for the beginner course and the
80-meter transmitter hunt.

Santa Fe Dam Recreational Area is in the city of Irwindale near the intersection
of the 605 and 210 freeways. From 605 northbound, take the Live Oak Avenue exit
and go east. From 605 southbound, take Arrow Highway exit and go east. In both
cases, you will merge into Arrow Highway westbound. The park entrance will be
on your left, opposite Azusa Canyon Road. Alternately, from the 210 freeway,
exit at Irwindale Avenue, go south to Arrow Highway, turn right (west) and look
for the park entrance on your right opposite Azusa Canyon Road. Vehicular
entrance and parking costs $10 per vehicle. After the entry kiosk, continue to
the first stop sign, go straight through the intersection and then turn left
into the parking lot at the end of the short road. See the map below for more
details. Look for the orange and white orienteering flag. Talk-in on 146.52
MHz simplex.

A map to this location is at For your GPS navigation system,
it's at 15501 East Arrow Highway, Irwindale, 34.113484N, 117.941549W.

If you have questions, send e-mail to The park office will
not have updated information about this event.
