All Day
Transmitter Hunt
Hiders: Bob WB6JPI and Glenn AB6PA
I had a PLAN. I wanted a hide to bring the hunters
into see the train loop in Tehachapi. This is a 4000 ft
loop of track that elevates 75 ft as it completely circles
a small hill. It is the 7th world wonder of
railroading.
No!! that was 6 years ago exactly. the last time I had
hidden an “all-Day” all day hunt. But again I had a plan.
I wanted to hide between Diamond Valley Lake and Skinner
Reservoir west of Hemet. In early March my Son-in-Law Andy
and I drove around the area and determined that the only
way from the east side to the west side was to go around
the lakes. Nothing on the maps or on the GPS crossed in
the middle between them.
We also noted that De Portola road does not go north into
Hemet. So if you were in Hemet you would have to go down
R3 (Sage Road) to east Benton then west to De Portola and
North to get to a T hidden there. This is a 12 mile
journey.
When I hunt I usually separate the multiple transmitters
by using the “T” numbers. These are usually sent in code
and are in the vicinity of the call sign identifying the
hider. I assumed that hunters also used this scheme and
that if I could mess up method then hunters would be
tracking the same transmitter they had just found or
looking in two directions for the same T number. Coming
from multiple transmitters. With the Arduino
computers being so cheap and powerful, I programmed a
transmitter (Baofeng UV5R) to sent IDs of T1, T2, T3, T4
at various speeds and various timings for 16 combinations
before repeating. The second and third transmitters were
the same but changed the order of the four IDs, Since all
three transmitters were identifying as these four
transmitters and there was not fourth transmitter, thought
that this would cause a lot of confusion and bearing
crosses all over the landscape.
When hunting Scott last month I was bothered by the N6MI
burst every couple minutes. Too short to easily get a
bearing and not often enough to do anything than to sit in
one spot and wait for several transmissions. Great idea. I
found that the FT857 had a feature called “Beacon Mode”
buried in one of its couple hundred menus. Here we go.. I
could only set it up to transmit for maximum of 255
seconds (4+ minutes) but my call is longer than Scott's so
the longer time should keep things interesting. Since I
have three of these radios why not have two of them mobile
and one fixed.
Andy returned to Illinois and I scheduled eye surgery for
the Thursday before the hunt. I was restricted to lifting
lightly but I could drive (I can’t read but can see great
beyond my arms length.) I recruited help in the form a a
very willing and capable Glenn AB6PA. I explained to Glenn
about what I had in mind and he immediately came up with
his own multi-ID T. This was the T11-16 below. I modified
one of the FT-857s to match his and set it up to go into
his car. I had some 12 transmitters and
we had Glenn’s two. Should be enough.
I decided to have the “come-on” transmitter located in NE
Hemet. This would bring the folk into the Hemet valley and
for sure they would attempt to get to De Portola to get to
the rest of the transmitters.
We had a PLAN.
We never got to the plan.
We met at 7 AM at the come-on transmitter T-10 running 40
watts into a 13 element wide spaced Yagi antenna
horizontally polarized and pointed at Mt. Baldy It
was located at Marshall st. ¼ mile South of Florida
Ave, It was heard in a lot of LA and Orange County and
even in the valley.
Next we went to check out if indeed De Portola Ave. went
through to Hemet. It does!!! In fact it is such a nice
dirt road we put T-9 near the top. It was a AF6O box
running 3 watts into a 4 element vertical beam pointed
North.
The next T we hung was on another pre judged situation
that there was no pass from east to west between the
lakes. Crown Valley road does make it through to Rawson
road even though it is not at all clear on any maps. My
GPS had no idea that Rawson went more than a few hundred
feet. We stuck a big transmitter there 30 watts into a 10
element beam pointed south toward Mt Palomar.
Next Glenn’s transmitter, Iding T11 thru 16 was supposed
to be at the end of Alden St. but between the time Andy
and I located the nice spot they had gated if off so we
compromised by a 1/4 mile of two tire tracks East and
stuck it to a fence south of Alden St.
T-1234 was located south of Benton on a pipeline street at
a cutout . It was using a 4 element beam pointed north.
T4321 was located on top of a hill NE of Skinner
reservoir. And had a 6 dB Ringo antenna.
That’s it. With the many voices it must have seemed like a
dozen transmitters.

T 1234 was not found. It was located just off Benton
the path from the east to west south of lake Skinner. The
two teams used the newly found connection using Crown
Valley and Rawson Rd and never had to go south to Benton
or north to Domengoni PKW.
No one has commented on the two 857 mobile transmitters
Iding every 4 minutes.
There was also an outsider from Lake Elsinore that had a
voice transmitter on for a while.
The best laid plans etc..
Thanks Glenn for stepping up in my time of need.
