Whats The Frequency?

Earlier this year, we got a very nice FM transmitter from a Canadian company. We set it up and tested it with very good results. We selected an unused frequency on the FM band and then thought all was well but..... somehow a few months later when we were retesting it, now there is a radio station on it! Rrrrrrr. We assume that its a new station or thats its bleeding over into the frequency we had chosen. So began another search and selection process and now the frequency is: (DRUMROLLLLLLL) 87.9! So now, you can listen to the music from your car on 87.9 FM. How do you know what frequency you can use? You can tune your car radio listening for faint static between stations or visit this website: http://www.radio-locator.com/cgi-bin/vacant
Add your zipcode and it will predict what signal strengths and locations for your area. I found its not 100% correct but will give you a pretty good idea where to look on your radio. By the way, the place where we got the transmitter is at the Canakit company. http://www.canakit.com/
We made 2 signs from plywood and painted them red and white to let viewers know where to tune into so they could hear the music. These will be posted on the front and side of the house.
