Hey guys... I just got a new fm transmitter for the car... In order to get the best performance possible out of it, I went & found a list of all the local FM stations, mathematically calculated the largest portions of dead air on Long Islands airwaves & determined the median dead spot between all the transmitting frequencies.
I discovered the best frequencies to tune it to are as follows:
-any frequency below 88.7
-any frequency above 107.1
So there ya have it... Just wanted to put this info up in case someone else might find it useful.
I personally plan on busting my transmitter open & soldering an extension onto the antenna wire to eliminate interference from commercial stations entirely.
(Don't tell the FCC)
