There was a very good turn-out, thirteen teams, for this Fremont
transmitter hunt put-on by James-N1DDK and Andy-WD6CJK.
The start instructions were announced by radio from
James-N1DDK, find two transmitters, 1st-hard TX 146.415MHz and then
2nd-easy TX 146.490MHz, mileage to both will count towards winning.
I read some pretty poor initial bearings (I need to
practice) of 340* to the hard fox and 347* to the easy fox. The real
bearings were 306* to the hard and 335* to the easy. Because of my
bearings, I started towards Mission Blvd. but, then changed course,
following my AHHA Doppler.
As you can see from my GPS track, I sort of zigzagged
my way towards fox-1, also checking and plotting the position of fox-2
since mileage towards both foxes counted and if I got to close to fox-1,
I would not hear fox-2.
Upon arriving 302 feet from fox-1, I started my foot
pursuit with my
4-element beam and new
Sniffer MK4. I
have to say this combination of close-in equipment is working out great.
James-N1DDK fox-1 was parked on an adjacent street. Within minutes,
Don-KD6IRE and Henry-KF6PCE came walking in to find fox-1 too.
Having a good idea of where fox-2 might be hiding, I
drove off in search of the last transmitter. Andy-WD6CJK setup a pretty
good (you can't get there from here), that I got tricked into. Fox-2
seemed to be coming from Morrison Canyon Rd., when I got there, the
signal was coming from Canyon Heights Dr., a dead-end section of road
that you have to drive 1.6 miles around to get to. I think a lot of
hunters got caught up in this trick.
After the hunt, the initial rule (mileage to both
foxes count towards winning) had changed to, not having to find fox-2
and mileage to fox-1 was all you needed. Hunters who did not drive up to
fox-1 but, walked to it, had .3 miles added to their mileage.
Dinner at Mission Pizza was great, with good food and
good company.

EQUIPMENT I USED
1) Arrow 146-4-II,
Four element yagi.
2)
VK3YNG Sniffer MK4,
I used it as my initial bearing receiver for both fox-1 and fox-2. Additionally,
I used the MK4 as my
U-R-Here radio which displayed my
progress towards both foxes exceptionally well. I also used the MK4 as
my close-in sniffer with my Arrow 146-4-II.
4) Compass,
Protractor and Map. I plotted my initial bearings on a laminated
(printed) TOPO map, which didn't help me at all, since I plotted some
very bad bearings.
5) AHHA
MicroFinder Doppler, Worked very well, pointing to both foxes
through-out the hunt.
6)
Standard C5900DA, Mobile tri-band radio. Your radio doesn't have to
be the C5900DA, any mobile radio will do, as long as you can scan or
receive all the FOX channels and the talk-in frequency. I use my mobile
radio as a distant U-R-Here radio and switched to my Sniffer MK4 when I
get really close. The MK4, attenuation level-7 seems to be the magic
number to stop and walk.
7)
Garmin StreetPilot-III. Street level mapping helped me find streets
I was not familiar with. I should have used it to plot shortest routes
though, my judgment on which streets to take were slightly off.
See you on Feb. 15,
2003, Pleasanton Hunt.
