I spit out my coffee when you said we're going to have a teaching moment😂

Love the teaching moments. Learn so much from reviewing circuits. Thank you.

It was just the bloody connector all along! First rule of electronics repair: Thou shall check voltages/connectors!

Damned hamsters - they're in on it with the mice!

Technically PIN diodes work on the amount of power into the device. If you measure the output power of the attenuator, you will find that the attenuation is not linear with the voltage. It also depends on the input signal power level. For example if the input signal power is - 30dbm, your drive to the attenuator might be - 10dbm, this changes based on the IP3 curve. A 0dbm signal could require a positive signal like 3 dbm.

Enjoying this series. Looking forward to retirement so I'll have more time to do some of this same fun stuff but in my case with more of a focus on RF and radio communications.

I hope parts 13 & 14 answers the questions I have. What is the function(s) of those funny little black and white slide switches? What is the function of that added-on (?) perf board circuit located in the same general area, I say added on because it doesn't appear to have the same build quality as the rest of the modules.

Ah! The hamster effect. Seen it before and it's not pretty. This is a great presentation.

If it was easy, we wouldn't be 12 videos into this journey 🙂

You're 12 parts in and you're seriously telling me you didn't check for hamsters 🤦♂

Maybe someone in the past stuck a probe tip in that connection and broke it ?. Like the short videos ,better than one long repair video.

This presentation style adds drama, intrigue and suspense! Better than a whodunit mystery novel. This is really great stuff, the journey is it's own reward.

Its always a crapacitor (except when its a diode.

Ir's always a electrolyte or tantalum capacitor. Even when is not.
