The EICO 150 Solid State Signal Tracer redux: Noise.

Monday, May 11, 2026 at 11:14:27

The EICO 150 signal tracer that was recently on the bench works, but it has some other problems.

Mainly: Noise.

The output is very noisy, and I want to track this down. I thought about putting this aside until later, but it has me intrigued and I want to get to the bottom of it.

This series will deal with isolating and tracking down the noise present in the unit - noise that is present on the output as popping and crackling.

Stay tuned!
