Here is an E-Caller that I built for my predator hunting Times. Now this is not cheaper than buying a Spitfire, but you have a longer range, your sounds are with YOU , you don't have to program a remote, you are not limited to 24 sounds displayed/played at a time and you have the ability to upgrade to a better MP3 player that can hold 8-16 gigs of sequences. I don't even use single sounds just sequences.
I have experimented with several types of enclosures etc. and this one is by far the sturdiest and the best deal. for $20.00 you get your battery, charger, housing already hooked up to a switch. Use the reflector as a way to hold the speaker and shield the antenna from the magnet on the speaker. It screws to gether zero hot glue necessary. Only thing left is to build a voltage regulator fixed for 9volts and hook it up. You will have to remove all of the circuit boards from your Nady 151 receiver and it will barely fit, you will have to remove the wall charger from the rear and move the battery all the way to the rear and velcro it into place so it won't move. If you are not electronically inclined I will try to explain how to built it. IN all reality if I could hook up with the components for this wholesale this could probably be built for under $100.00. It took me literally 1 hour to assemble it. Sorry for the blurry pictures, but this is just video and picture from my cellphone. Anyway. I hope you can build this it takes little time and can be done completely in about an hour. The only power tool think I had to do was drill a hole for the antenna, but I am going to mount a permanent antenna on this. I believe that experimentation is great. It is not for those trying to save a buck, this was more than a labor of love, I spent probably about 60.00 more on other parts that I am not using now for this caller, extra batteries etc. But I think I can use those parts for my portable e-decoy. I do believe that I will change out the 193 for a 30watt stereo amplifier so I can have a jack for an auxillary speaker that I can use. One thing you have to know is that the Nady151 is awesome because it gives the proper line-leve input to the amp. Where a direct wire seems to clip the input to amp. I think this is one of the best callers I have built, ane even though I have a bunch of western digital callers laying around, I won't be using them for anything other than backups now, this is louder and clear than the SPC5 horn as well. Plus for those of you who can legally use an e-caller in deer country you will get an awesome rattling horn sound because of the two-way speaker.
