Musical horn module

[GARY MINKER]

The speakers are/were made by Electrovoice and were also carried by Radio Shack. Just scratch the wires to the battery for the resultant basic test. If you hold the wire on there it will just go click. You can hook it to your pocket mp3 player or transistor too. Any similar re-entrant horn design will work for this as an emergency replacement. A quality speaker will perform very poorly. The horn module does not exactly put out real "audio" as you might think. It is a square wave that makes use of the horn/speaker design for tone and volume.

You should hear a crackle. If you do not, it's time for a new speaker. Incidentally, I purchased my two speakers from PMMI. They gave me a great price and they happened to be color coordinated with my roof as an added bonus. Also, it is great fun to have your horn programmed with tunes that suit you. Several years ago it cost $125. I had fun selecting the tunes and the cows seem to enjoy the tunes I play for them. It's a nice diversion. Eric Perplies 96 42 WBWL currently in Fredericksburg, TX
