Mike, <br> <br>A few questions. Other than the GPS which I already own, what else would I have to buy to make one of these transmitters? Also how would I find out if there are towers around where I live so that I could transmit the signal? Is there special software that had to be written? <br> <br>Thanks, <br>Mike Hill <br>H20 #791 <br><br><br>
