R9 won't even pull down properly against the load. The source follower is active on one side, passive on the other and R9 has to pull down through a 100 uF cap? Good luck.

Yeah. I should have read further in the docs. I'll correct my answer. (It is currently wrong. But I'll fix that.) And thanks. +1

Was it always like that (terrible and quiet?) Or is this a newly acquired behavior because something has been damaged?

Well, C1 would seem to be a problem. One end is at a fairly high impedance. Not so good. You may want to talk a little more about what you are trying to achieve, I suppose. It's possible you don't need...

The frequency you are considering is right at the domain rates for simple spontaneous photon absorption and subsequent re-emission. Finding a material able to rapidly rotate its magnetic moments so as...

The unknown units are Siemens also known as \$\mho\$. If you divide it into 1 you will get Ohms.Of course when you relate the voltage across the capacitor to the current in the resistor (or capacitor,...

Thanks, Tim. +1. Before I commented, I checked my view by reading this from Feynman. I doubled back through again and although I can imagine tiny atomic current density (or a portion assigned to...

Datasheet on the sensor, please. I see a resistor there. But you say "voltage." I suppose the divider network might answer my question. But I'd very much rather just see the datasheet for myself. Also,...

@FranciscoMaggi I suspect the hint was about driving the base without a resistor arranged to rapidly dissipate out oscillations since it is very easy for RF transistors to ring when given half a...
