It was a dark, foggy and stormy Friday afternoon with visibility a hundred feet or so and a nippy 40 degrees when Joe Loughlin KE6PHB and I pulled in at the cabin of Mary Walke KJ6ZIW in the Laguna Mountains of San Diego county. We have used this cabin several times in the past for ham radio events but had never seen weather like this before. We wanted to get up there early and possibly put out the 5 hidden T's on Friday afternoon instead of running around on Saturday morning. KE6PHB had finally reached the point on his new "PHB-101" transmitter design so that we could put them out on Friday, set to come on at 10 AM Saturday, but it was just too darn cold!
We huddled up in the cabin and checked all the other gear, practice T, back up Pic-Con's, HTs, borrowed sniffers, batteries, locks and cables, etc. The cabin finally warmed up with the space heater, so we almost got a good night's sleep anticipating good weather in the morning.
Unfortunately, the weather did not live up to its forecast. It was still cold, wet and foggy. Luckily we could drive a loop and not have to walk through miles of wet brush to set out the T's. We spotted the last T at 9:30 and headed back to the cabin to prepare for the onslaught of hunters. With the weather this bad we were wondering what we were doing here. Hunters started arriving and the first team went out at 10:25 AM. The last team started at 1:55 PM, just short of the 2:00 PM deadline we had set so we could start the BBQ around 3:30. The only deviation we made during the day was to allow Tom Franks KJ6VOC and his three sons Daniel, Aaron and David to take a break during the hunt for a "dinner stop" as they were one T short at 3:30. After dinner, they located the fifth T and checked back in.
Here are the results:

We had a total of 18 people on site with 16 hunters, not bad for an "all weather, all terrain" hunt. The BBQ was outside with almost everyone eating inside due to cold weather.
We look forward to seeing more folks out on next year's hunt. It should be at a lower elevation and much better weather. Thank you for the BBQ donations, every bit helps!

After 0.6 inch of rain fell in Fullerton on Thursday and Friday, the hills were a bit muddy and slippery on Saturday. But cloudy skies meant comfortable temperatures as members and friends of the Fullerton Radio Club gathered in a new location for the annual "Antennas In The Park" event. The usual HF operators didn't show up this year, but fans of ham radio direction finding had fun building antennas and searching for hidden transmitters.
Many of the attendees were newcomers this time. They tested their antennas with three practice voice transmitters near the gathering point. Then they set out on the five-transmitter ARDF course within the 40-acre park. Here are the results:

I put out two transmitters on the 80-meter band, one close by for training and a second one in the northeast corner of the park. Here are the results for the second transmitter, which sent CW continuously.

The sixth annual on-foot transmitter hunt on the campus of California Polytechnic University in San Luis Obispo took place under beautiful cloudless skies. It started with a building session for two-meter measuring-tape yagis and active attenuators. Then individuals and groups went out on the course that was described by one experienced hunter as the hardest ever at this location. Nevertheless, everyone reported having a good time.
Something new this year was APRS trackers on some of the hunters. According to organizer Stanton Wu KK6AEE, "In the groups, one person held an APRS tracker and another person held the directional antenna. The trackers can also be clipped to pants, so people that hunted alone did that while hunting. Not everyone had a tracker because the club didn't have enough trackers for that."
KK6AEE continues, "A map of the campus with the location of the trackers was projected onto a screen in the hamshack, so people that stayed behind to cook or log times into the computer could watch the hunt. I was one of the people that stayed behind to help out, and I thought the trackers were neat. I routinely checked the screen to see how some groups were doing. I helped hide the transmitters too, so I knew where they were and how close the hunters were to finding one."
Here are the results as provided by the organizers:
Thanks to KK6AEE and all the other volunteers who organized a great hunt, and thanks to Marvin Johnston KE6HTS for providing kits and helping participants build their equipment.
Fine weather and a good turnout made for an excellent day of ARDF at Bonelli Regional Park on March 21. We announced that the emphasis would be on training, so there were a total of 15 transmitters on two bands ready when the antenna/attenuator building session concluded. First, there were three voice transmitters on three separate frequencies for antenna testing and bearing-taking training. For those who were ready, there was Marvin Johnston's full five-transmitter two-meter course with radio foxes scattered throughout the park. For those who wanted a bit more practice before tacking the full course, I put out five low-power foxes nearby, all on the same frequency with the standard 60-second ARDF transmission sequence. It gave the newcomers an opportunity to learn how to attack a course with this timing. The experienced hunters could use this as a "sprint" course, with the objective of finding each transmitter on its first cycle.
Rob Brigham W6ZH tried ARDF for the first time at Vasquez Rocks in February and came back this month to build an antenna attack another full-size course, which he did with splendid results. Also building an antenna/attenuator setup was Karthik Malasani of Santa Monica, whose first time on an ARDF course was assisted by Tom Gaccione WB2LRH. Here are results of the full two-meter course.
Also on this course was Brooks Kachner W6BJK, joined by his son, daughter-in-law and granddaughter.

Foxes with "0.00" times were found after the e-punch units shut down at 3 PM.
I put out two transmitters on the 80-meter band, one close by for training and a second one a little over a kilometer away. Here are the results for the second transmitter, which sent CW continuously.

It's been ten years since we have done ARDF at the Vasquez Rocks Natural Area near Agua Dulce. This unique site has been used in countless movies and TV shows and is a popular hiking and climbing destination. Orienteers describe the map as very technical, but also very well done. Weather was excellent.
Having our President's Day ARDF session combined with a Los Angeles Orienteering Club meet had its good and not-as-good aspects. It exposed many classic orienteers to radio-orienteering, but there was some confusion about registration for the two separate activities.
This was an unusual opportunity for residents of the Santa Clarita and Palmdale areas to have ARDF close by, so we had a good number of newcomers who came out to try RDF antennas that they had recently built. My "easy" practice transmitters proved challenging for some but "duck soup" for others.
Of those who had early success, many tried the full ARDF course, or at least went out to find one or two of its transmitters. Unfortunately one transmitter went off the air soon after the start, so the most that anyone found was four. Here are the results:

Control numbers with asterisks at left were regular orienteering controls, punched in error. Steve Morse KI6HGH also went out on the full course but was not timed.
Thanks to Marvin Johnston KE6HTS for taking time away from his LAOC duties to set a good ARDF course, and he thanks everyone who helped him pick up transmitters afterwards. April Moell WA6OPS took care of all the scratches, bumps and bruises as usual. And special thanks to Julianne Walsh KI6DYX, who gave one-on-one RDF training to several of the newcomers.

Southern California weather forecasters got surprised on the second weekend of January 2015. Early in the week, they thought that there was only a small chance of brief showers on Sunday morning. But Saturday afternoon, the rain started and continued intermittently (and sometimes heavily) through Sunday afternoon. Our Sunday ARDF practice was mixed in with the state orienteering championships for Navy Junior ROTC students, so the show went on. From a table under a pop-up shelter, we were ready to send participants out to find three practice two-meter transmitters, one practice 80-meter transmitter, a five-fox two-meter ARDF short-course, and another 80-meter transmitter about 650 meters away atop a muddy hillside. No transmitter went unfound.
Attendance was much lower than expected, of course, but those who came out were in good spirits and had a good time. We're already planning another session in this park for a warm-weather month.
Besides setting the ARDF course, Marvin Johnston KE6HTS was busy solving problems with electronic scoring of the ROTC event. April Moell WA6OPS only had one minor wound to patch up, so she had plenty of time to explain ARDF to the orienteers and park visitors.
