Evening Transmitter Hunt Recap – August 27, 2014

An evening transmitter hunt was held August 27 by the CARP Central Valley Transmitter Hunters. I, Rob Mavis AE6GE, was the fox for the hunt.

The hidden transmitter consisted of an HT set to 1.5 watts, controlled and modulated with a Byonics PicCon and a M² 2M3 four element beam. The beam was attached to a piece of PVC pipe stuck into the ground so that it was only a few inched off the ground and vertically polarized. The beam was pointed north parallel to a chain-link fence (the start point was to the east.). Due to the proximity to the ground, the chain-link fence and the numerous fences around the park, high school an ponding basin, the hunters had to be seeing many signal reflections.
The hunt stated at 7:45pm, just as the sun was setting. There were no lights in the park itself, but light from the surrounding properties provided little usable light in the park. I set up a camp chair across the park behind a large pine tree to sit back and enjoy the event. Continue reading Transmitter Hunt Recap – August 27, 2014

May 10, 2014 Transmitter Hunt Recap

CARP and the Central Valley T-Hunters held a Transmitter Hunt on Saturday May 10th. The start point was at Four Corners Park & Ride (Hwy 41 & 145). Six teams started the hunt around 10:00am.

Using one watt and an Elk log periodic antenna, the fox was at Owens Mountain Parkway, also known as the intersection of Temperance and Alluvial avenues. This location provided the fox with easy access to food, beverages, and bathroom facilities while the hunt was underway. A secondary low power transmitter was also setup on the same frequency making it unfriendly to find when the main fox was transmitting.

With one watt of power and the antenna in a horizontal position, the main fox transmitter played to the skilled hunter with proper equipment. This is where a yagi antenna turned horizontal can make all the difference. The hunt was milage based, so constant stopping helps to prevent overshooting the fox.

 

Three teams came in within an hour, with the other three eventually coming in much later. Five of the teams were able to find the secondary transmitter, with one giving up after being within a foot of its position.

Congratulations to the team of Ken WA6OIB (Driver) and Ron N6MTS of having driven only 17 miles, as well as arriving first. Well done to the other teams who stuck with it and finished the hunt.

1. Ken Holden WA6OIB & Ron Hunt N6MTS – 17 miles driven
2. Rob Mavis AE6GE – 19 miles driven
3. Michael Cederquist KD6LDA – 22 miles driven
4. Matt Goodwin KJ6YLJ & Greg Goodwin KG6YZN – 32 miles driven
5. John Morrice K6MI – 33 miles driven
6. Mike Herlihy KG6MSV – 46 miles driven

The Fox at Foothill Elementary School near Prather

CARP and the Central Valley T-Hunters held a Transmitter Hunt on Saturday March 9. This hunt the start point was at Letterman Park in Clovis. Five teams started the hunt at approximately 10:00am.

John K6MI was scheduled to be the fox for the hunt but had a conflict at the last minute, so Rob AE6GE volunteered to be the fox. After a hasty scouring of the map of the area, Rob hid at Foothill Elementary School, just south of Prather. Using a 5-watt transmitter and a 2-meter M2 Eggbeater antenna the fox was hidden down off the backside of one of the baseball diamonds where an active game helped to camouflage the foxes truck. Only one transmitter was used in an attempt to increase the difficulty by not allowing the low power transmitters to give away the location when the hunters got near the fox.

Area Terrain Map

By using low power the signal just barely made it over the two hill tops that were between the fox and the start point.  The hilltops helped to confuse the hunters a bit because almost immediately after the hunters left the start point the signal was lost, forcing the hunters had to rely on their initial bearings to find the signal again. The hill also helped to cause some of the hunters to overshoot the fox and head up the 4-lanes of Highway 168.

Add to that the fact that the signal was circularly polarized also seemed to give some of the hunters some trouble as well. But eventually almost everyone found the fox.

  1. Rick W6KKO – 1 Hour, 17 Minutes (28 miles)
  2. Ron N6MTS / Ken WA6OIB – 1 Hour, 21 Minutes (45 miles)
  3. Mike KD6LDA – 1 Hour, 33 Minutes (51 miles)
  4. Gray WA6BJY – 1 Hour, 47 Minutes (54 miles)
  5. Duane KI6QEL – DNF

Congratulations to Rick W6KKO for not only finding the fox in the shortest amount of time, but also in the shortest miles driven. Duane KI6QEL had a prior obligation as well so he only hunted for the short period of time before he had to leave.

Thanks to all who participated and we will see you all at the next hunt!

W6KKO – First to Find N6MTS and WA6OIB – Second Place KD6LDA – Does he see the fox? KD6LDA – Third to find (he walked over the hill because he didn’t want to drive his Camero down the washed out dirt road)

WA6BJY – Fourth to Find

Hiding in Plain Sight

Jan 4 T-Hunt Group

On Saturday January 04, 2014 the Central Valley T-hunters got together for the first hunt of 2014. We had a great time. The hunt got underway at about 1015 in the morning from Letterman Park in Clovis. Matt KG6YLJ and Greg KG6YZN were the fox.

This hunt had the fox hiding in plain sight on the top level of the parking structure at River Park. Rob AE6GE was kind enough to loan his picon and icom handheld to Matt and Greg. The hunt got off to a rocky start but all the bugs were worked out within a few minutes.

Hidden Transmitter

Matt attached a three element tape measure antenna to the radio and had it pointing toward highway 41, giving a false direction to the hunters as most traveled north. At about the half hour mark the antenna was moved and pointed toward In and Out Burger in attempt to misguide the hunters. Around 1100 the antenna was changed to the rubber duck antenna in a further attempt to misguide the hunters.

At about 1130 Duane KI6QEL drove along the upper deck of the parking garage and past the transmitter that was sitting on the concrete wall between two parked cars, clearly visible to anyone passing by. There has to be something said about hiding in plain sight as the green ammo can blended into the background of the buildings across the street. Duane continued along the parking structure about 10 parking spaces and stopped to take another reading. Even at the third harmonic his radio was picking up the transmitter at S-10. Duane soon left the parking structure and was observed by the fox driving through the parking lot around Chipotle.

About 1140-1145 hours Rob AE6GE came up the upper level and drove past the fox as well. I must admit the fox was somewhat camouflaged as the dual band antenna had been removed from the car, but the license frame does have his call sign engraved on it. Rob continued down toward Macy’s parked and started to take bearings with his tape measure antenna and attenuator. After several minutes he started walking the parking structure until he came upon the fox.

John K6MI had been driving around the various parking lots and had even walked about a half mile around River Park seeking the elusive fox. At one point John was stopped by a bank security guard who was enquiring about the strange equipment he had. John took this opportunity to do some Public Relations work regarding amateur radio. As John was cruising the parking lot by Joann’s he spotted a group of unsavoury looking men standing on the parking structure and came to join us.

When all the mileage was checked John had only driven 11 miles followed by Rob at 17 miles and Duane at 19 miles. In keeping with the tradition of ending the hunt near a Me and Eds, the group broke bread at the Me and Ed at River Park. Fun was had by all.

Come and join the next Thunt on March 8, 2014. John K6MI is scheduled to be the sly fox. Get on the Central Vallley Thunters mail group and join the fun.

On Saturday March 10, 2012, I was the fox for the CARP Transmitter Hunt. The hunt began at the Park and Ride at the intersection of Highway 41 and 145 in Madera. Four teams participated in the Hunt that started promptly at 10:25 am.

The hide radius for this hunt was 10 miles from the start point.  The transmitter was hidden on the Miramonte High School campus located at the corner of Highway 41 and Road 200 (North Fork/O’Neals turnoff), a driving distance of 9.1 miles from the start point. My vehicle and the transmitter was tucked away behind one of the buildings so it could not be seen from the road or school parking lot.
