WB6JPI Bob (Jippy)
The Hiders Story
I had a plan.
I have a few things I want to try that are new. The first is a group of transmitter (a gaggle) that all sound alike and are located so you have difficulty getting between them to separate their bearings. IU also didn’t want them to have any identifying haracter to their transmission other than the transmitter number which occurs after the majority of the transmitter.
The second is using the Baofeng UV5R hand held as the transmitter. I have assembled a controller that is a Digispark processor coded to have 16 different pitches delays and code speeds. This is a new idea in hidden transmitter in that the radio with normal battery is $31 (Amazon), a 3800 mAh battery is $12, the mic/speaker connector and wire is $7 the digispark is $9 and the antenna connector is $7 the software is free so the whole thing is $66 and there is no mods to the dual band hand held and it will make 1 or 4 watts with every know bell and whistle as a hand held. My gaggle consists of three of these Baofengs and two micro Ts that send CW and T1 or T3 for a total of 5 transmitters.
The third thing I wanted to do is to keep everyone lively in the hunt by having at least One transmitter that was just annoying and to have on that is hard, very hard to find. I made the first requirement by having a high altitude 200 mW transmitter iding WB6JPI every 5 seconds. The second was a miserable failure as you shall see,
Another thing I wanted to evaluate is a Software Defined Radio (SDR) I just got working on Thursday and could not get it ported to a portable computer so it would only run from my main computer at home. So the hunt needed to be near home so I could evaluate the SDR for use in transmitter separation and as a hunting accessory. This worked out very well and the SDR performed admirably in seeing transmitters I could not hear and seeing transmitters being covered up by other transmitters. It is going to be a useful device in multiple transmitter hunting. If you already have a computer in your hunt vehicle, it no big deal to add this receiver. It is a $7 item and plugs into a USB port and into a antenna on the car (what not another antenna!!!). If you want a better one than I have you can spend up to $20 for a “FunCube Dongle”. Mine is just a lowly DVB RTL SDR Dongle
So now I have my objectives and on to the hunt…
my 30 watt transmitter and the 13 element wide spaced
antenna would be the transmitter no one should find.
It was to point at
problem with T10 was that it would not have much
(enough) signal to get in to LA so people could start
the hunt. So I found a spot on
To get people back into the Cajon pass I hid T-5 a talking T, 40 ft east of the 215 fwy, but 2 miles of dirt road to get there.
Gaggle was to be located on Okie Flat road just east
of I-15 and would be above I-15 by 1000 ft. On Tuesday
when I checked all this out Okie Flats was open, but
on Saturday Morning it was gated. I decided to move
the Gaggle to the same road I had used in the last
hunt, a little dirt road west of I-15 off of
comes the mistake. I wanted to hide a transmitter up
on top of the hill and found a spot in
think Deryl/Ray did just that He went from the 15/210
found T5 on to
Deryl/Ray must have left T10 toward Silverwood, went back to the 15 via 138 And there they found T1, T2, T3, T3A missing only T1A in the gaggle. They is the winners. They had found 9 of the 10 transmitters.
