can one build a remote predator caller? importing it to africa will be expensive.
i was thinking of a combination of a memory stick and a industrial remote.

has anyone ever atempted a home build?

I know many built their own using MP3 players, small amp from radio shack and a remote from something. They used a jumbo plastic coffee mug for the body...Here is one such guy's info from...

I just finished building my own Digital Electronic Caller today. Actually this isn't the first one I have built, got talked out of the last couple I did over the years.

To start with I used a Rio 600 MP3 Player I picked up off of E-Bay CHEAP. I had the sounds already. A couple years ago a buddy and I bought a few Johnny Stewart Calling CD's, recorded the tracks we wanted to Gold Wave Sound Editing Software and isolated ONE sound Loop from each sound and burnt these tracks to a CD. It is a simple matter of then downloading these sounds to the MP3 Player.

Next up a Speco SPC-5 PA Speaker (this is the best sounding PA Speaker I have found) was mounted in the bottom of an insulated Coffee Mug (flush with the end of the Coffee Mug, after cutting the bottom out of course). I then removed the Circut Board from a Radio Shack Mini Amp / Speaker and mounted it in the Coffee Mug with it wired through a seperate Switch and Indicator Light (the light is so I do not accidently leave the amp on when not in use). After this was done it was a simple matter to plug the speaker into the Radio Shack Mini Amp and a Patch Cord between the MP3 Player and the Radio Shack Mini Amp.

That was about the extent of it. I have 14 tracks on the MP3 Player, and they vary in length from a few Coyote Howls to 1 mnute of Distress sounds. If I want continous play I enable the repeat track function on the MP3 Player. These are the sounds I have on my MP3 Player.

1 - Coyote Locator
2 - Coyote Pup Distress
3 - Despirate Cries / Cottontail
4 - High Pitched Cottontail
5 - Cannine Puppies
6 - Distressed Housecat
7 - Meadowlark Distress
8 - Squealing Woodpecker
9 - Fawn Bleating
10 - Rodent Distress
11 - Coyote / Grey Fox Fight
12 - Coywolf Barks / Howls
13 - Lone Howl Locator
14 - Lone Coyote Challange

I have a total of $70.00 invested in this caller at this time, not counting the cost of the Johnny Stewart Calling CD's we purchased a couple years ago to get the sounds from. There are also several Calling Sounds available on the net as FREE Downloads at the Western Rivers web site.

As it is now the Rio 600 MP3 Player runs off of a single "AA" Battery, and the Radio Shack Mini Amp runs off of a single 9 Volt Battery. With the Amp and Battery inside of the insulated coffee mug hopefully the insulation will help keep the battery warm. I modified a plastic cell phone holder to hold the MP3 Player to the Coffee Mug. There is room between the holder and the MP3 Player to slip one of those little chemical hand warmer packs to help keep this battery warm also in cold weather.

However I do plan on wiring in an Azden Wireless Remote to it in the future making it wireless. The Azden is a Wireless Remote Transmitter and Receiver designed for use with Camcorders, and just happens to work quite well for a wireless remote for an Electronic Caller. (I put an Azden together with a Johnny Stewart Preymaster Caller the other night for a friend, and it's range was right at 200 yards before it started cutting out). Both the Azden Receiver and Transmitter use their own 9 volt Batteries so that will add 2 more batteries to the total when I am finished.

The thing I like about making my own caller is if something breaks or wears out I can replace any part of it myself without having to send it anywhere to be repaired. It also makes for an interesting project in designing how I am going to wittle away at the coffee mug to get everything to fit and in the location I want it in.

If this is the fella I think it is I will update the info after he replies to me on yet another board...

I've used a small "boom box" AM/FM/casette player, and spliced in speaker wire to any small speaker. Computer speakers would do fine. Fidelity does not seem to be a critical matter...
