Glider Electronics Experiment #1 - electrical crosstalk demonstrated
Hi all,
I got a bit bored and started filming some glider electronics experiments. I am attempting to pitch them to be interesting and understandable even if you don't know much about electronics. First up: Glider Electronics Experiment #1 - electrical crosstalk demonstrated Available he https://RJPLancaster.net/ Best regards, Richard |

Dang!
Learned something there, let me tell you. I'm going to check my wiring after that demo. I keep picking up Linda Rohnstat on my radio, is this why? Nick T |

Electrical interference is a tough subject even for electrical engineers, such as myself. You presentation is an intuitive approach, which is much more understandable than, say, equivalent circuits. Keep it up. Tom |

Thanks all for the positive comments.
Got asked on the UK glider forum for a description of what the video was about. So in case anyone is debating whether to sink their time into it, here's a quick abstract: "Electrical crosstalk is a type of interference where the signals carried in one set of wires "talk across" into another set of wires. This video sets up a simple glider electrical harness, talks about how crosstalk might occur in it, demonstrates it occurring and illustrates the magnitude of the consequences to the pilot." Best regards, Richard |

Nice demo of cross talk. Last year I fixed a problem in our glider where the microphone wires were not completely shielded, as in your demo, and were picking up signal from the radio speaker wires, also not completely shielded. The result was intermittently the radio would squeal during transmit due to feedback from the speaker back into the microphone. It was intermittent due to the wires shifting slightly every time the canopy opened/closed. Shielding both the speaker and microphone wires fixed the problem.

Setting up these experiments I was intriged by how much small relative movements in the cables when they are bundled together, even at a single point in the cable run, can change the crosstalk. Will try to show that and the effect of distance in the next video if I can pull off a clean demo. Richard |
