All Day
Transmitter Hunt
Hider: Scot KA6UDZ
Transmitter 1 (T1) was located in a culvert at Mile Post 10.14 on the West side of Glendora Mountain Road (GMR). The transmitter was below the grade of the road but the horizontally polarized turnstile antenna was hanging from an oak tree and above grade. Transmitter power was 10 mW, but this transmitter failed to activate and thus was not found.
Transmitter 2 (T2) With callsign KD6LAJ went on the air at precisely 10:00 am. The transmitter fed a horizontally polarized omnidirectional turnstile antenna suspended from a tree. The tree was located along a fence behind the Road Division 518 Mountain Yard on GMR. The lat/long was 34°12'19.86" N, 117°48'58.02" at an elevation of 3,444 feet. This transmitter was intermittent and should have been line of sight from the start point and easily heard. The hider previously used this site (Within 50 yards) to hide a Sunday afternoon San Gabriel Valley Radio Club hunt sometime around 1994/1995 while an employee of the County Road Maintenance organization.
The Main Transmitter, T6, was located in a North facing paved turnout on Glendora Ridge Road (GRR). This was approximately 500 feet East of Mile Post 6.20. A more precise location is lat/long 34°13'26.7" N, 117°44'0.54" W at an elevation of 4,006 feet. The 5 Watt transmitter fed an 8-Element horizontally polarized Yagi aimed directly at Mt Baldy. The recurring 20-second transmission was a tone sequence followed by "KADUDZ T6". The transmission repeated every 80 seconds. T6 began transmitting at approximately 10:05 am. The start of transmissions was delayed by the unlawful skate board and skate-luge activity on GMR. Film at 11.
The first team to arrive at T6 consisted of KF6GQ and KD6LAJ at 12:15 pm with 34.3 elapsed miles. Don and Steve arrived from the West after climbing up GMR and finding T2.
N6MI and K6VCR arrived 8 minutes later from the East via Mt Baldy Road at 12:23 pm and 43.0 elapsed miles. They traveled a total of 50 miles before later finding T2 at 1:22 pm.
N6AIN arrived an hour later from the West after finding T2 at 1:23 pm and 99.4 miles traveled. This may have included travel up Angeles Crest Highway and back.
The hider watched the shadows begin to grow long before WA6RJN and KB6MGT arrived from the West at 5:30 pm and "Greater than" 99.4 miles. These miles too may have included Angeles Crest Highway and possibly even Highway 39. They stated that they had no signal an eighth of a mile to the West along GRR. At least they found T2 prior to arriving at T6 and didn't add to their "Greater than" 99.4 miles.
All teams found both operating transmitters (T2 and T6).
The final times and mileages were:

Based on both time and elapsed miles, KF6GQ and KD6LAJ are the winners of the hunt.
Special thanks to KD6LAJ for the loan of T2.
Without it, there likely would have been only one
operating transmitter. Mileages and times may have been
higher.
