Control an R/C car, boat or airplane? What is this transmitter? 900 MHz sounds like a public service two-way radio. However, these radios have more than a 300 ft range. A 300 ft range would sound like a R/C transmitter but there aren't any that work at 900 MHz. I will assume you are are trying to control an R/C thing-a-ma-jig. R/C receivers work at 27 MHz, 72 MHz, 75 MHz or 2.4 GHz. If your R/C transmitter works in the same band as your receiver, you can change crystals in both the receiver and/or transmitter, fairly easy. If you like modifying radio gear, get an Amateur Radio (Ham) License. You are allowed to build, experiment with and modify all the radio gear you want! Hams also use their gear for R/C.<br><b>References : </b><br>Amateur Radio operator R/C airplane pilot What are you trying to do? Control an R/C car, boat or airplane?

The frequencies are too far apart to work efficiently. If you have a modern receiver you can't change the frequency...if it's an older model you could replace the crystal IF they even exist. A 300 foot range for an unlicensed Part 15 FM transmitter is only average. A good one with a nice antenna can do closer to 1000 feet.<br><b>References : </b><br> Not as simple as it sounds.
