This is a JR RS300 Synthsized 3-Channel FM Receiver on 27MHz. The RS300's phenomenal processing speed supports its selectable, ultra-fast frame rate feature, which delivers response that's faster than the human brain's. And in addition to offering fully synthesized, crystal-free channel selection, the RS300 features 2nd generation ABC&W circuitry for optimum resistance to interference.
The RS300 27MHz will work with any JR Radio with a 27MHz module installed.
JR has a unique signal processing system called ABC&W. ABC&W stands for Automatic Blocking Circuit with Window. ABC&W systems have distinct advantages over single or dual conversion receivers. ABC&W systems create a very small electronic window that looks for the specific frequency that the receivers crystal is on. Any signal that is off spec for this window is rejected, and then the allowed signal is cleaned up, amplified, and re-routed through the window many, many times till all that is left is the pure signal on the channel that is coming from your transmitter and then sent on to the servos. This all takes place without any noticeable delay of response from your stick movement to the servo. This technology is the reason that JR can produce single conversion receivers that have fewer components and weigh less than other single and dual conversion receivers without the worry about outside interference.
