To stay on the legal side of the line, when making modifications to FCC certified devices, ALWAYS ask for documented assistance from the manufacturer. Its a good way to cover your backside. Make sure you have a “hardcopy” document from SSTRAN, with instructions on how to make the modification. And make absolutely sure you follow them exactly, to the letter, and document everything you do.
Before going back on the air, you should also do some bench testing before broadcasting with the transmitter. You are required, as a school radio station, to do some over the air signal tests to determine that the signal doesn’t extend too far beyond the boundaries of the school campus (Part 15 rules).
Check to make absolutely sure you are not interfering with any licensed broadcast stations or listeners. When you increase power, you increase the potential for interference. I go to the the FCC AM database and discover the clearest and best frequency for my station. Then, I listen for several evenings with a high quality shortwave-type receiver to see what kind of sky wave signals are present on the frequency of choice. At night, one watt can travel hundreds of miles via skywave.
After all this, you’re ready to throw the switch and become radio stars…..
