I have missed this notification. Sorry for the very late response because of this.
I did use a scope initially but ended up using a datalogger and PulseView because I got the timings more directly listed. I will have a look and see if I still have the PulseView .sr file available.
But when using a scope, I did have an even height of the pulses, not the two levels that you show. Could it be picking up another signal that is interfering (the small peaks), or does it all stop when you release the charging cable button?
I suggest to measure the distance between peaks and check the frequency of the interference I bet that is 50 or 60Hz (AC mains).
I tried this setup with an Arduino mega 2560 & ASK STX882. Code is exactly the same. Then I checked the signals on data pin of STX882 on the oscilloscope but the signals were not as expected I suppose. Are the signals supposed to be 433 MHZ for each duty cycle? I had same experience with a 315MHZ transmitter also. Can you please suggest what is wrong? Attached few images for reference.
