RC receiver outputs are simply a ~1. The indicated operating ranges suggest the use of a properly tuned antenna and high quality communication receiver. Dixon, 1998 (Marcel Drekker, Inc. 610 RF Receiver Module 433mhz / TTL RF Transmitter And Receiver Module Shenzhen KYL Communication Equipment Co. The transmitter will work up to about 30 metres and operates at 315MHz via a transmitting module contained in a 3-leaded metal can, soldered next to the transmitting coil. Be careful, as the audio may become very loud and distorted and the signal will be off the scope. Though this shortwave transmitter circuit can reach barely around 5 meters, but you can be increase the range. I realize the 433/434 band is crowded, almost every keyboard transmitter I've seen uses it, but I had reliable results with a sufficiently robust protocol. The performance and working of the wireless audio transmitter circuit is depends on the induction coil & variable capacitor. The receiver includes both an in-channel RSSI and an RF RSSI. 4 Channel RF remote built using PT2262 and PT2272-M4 IC from Princeton technology. 8- bipolar complementary metal oxide semiconductor (BiCMOS) Functional Description The CY7B923 HOTLink‚ transmitter and CY7B933 HOTLink receiver are point-to-point communications building blocks that.
