Hil all, i have a problem with Dorji Rf Receiver. My transmitter sends data in 53 second period but i cant receive them. I am taking rubbish signals. When i connect data pin to scope. I am seeing a screen like that
In addition. I cant see any data at logic analyzer.
Your scope shows a 500mV signal, are you using a x10 divider probe?
Otherwise something is very wrong.
What is your data rate into the transmitter? If it is too fast, it will not transmit correctly.
Rather than a picture of a standard module, a datasheet would have been better and some schematic of your connections to the transmitter and receiver modules.
By the way, what is the gash piece of wire wrapped around one of the module pins?

It is my construction. Yellow cables go to ground, green one goes to 5V, and orange cable is data cable. I connect it to PIC or Scope . All of them directly connected. There is no extra thing. That capacitor(47 uF), i soldered it as external to prevent AGC by looking IC's(SYN470R) datasheet which inside my receiver module.
