....also, the capacitor value usually needs to be a minimum of 22,000uF 25V.

Try significantly reducing the mic gains on both P1/P2. -12dB might be a good starting point.

Yes. The principle is that if you also ground the jack socket, say, to the airframe, you will create a ground loop which can cause many issues.

Right side only I believe.

Pleasure. Glad to hear that it's resolved.

Have you adjusted the microphone gains for your headset(s).
I found that it needed significant attenuation of -12dB or more for A20 and Zulu 2.
Without doing that receivers will hear significant compression/limiting and possibly distortion.

On a similar note, I've been designing a gauge for fuel pressure and run into more issues.
A gauge and a text value both driven from the same RDAC FP source show different values under simulation (but they do change with the slider)....?
Anyone else seen this?

Isn't this a QNH versus ISA (1013.25hPa) thing?

Ok, I've tried again. My conclusion is that it simply does not work. I'd like to think that @Rainier will step in and explain. No matter what I change in fuel setup calibration and RDAC sim. slider position, the simulated fuel level is stuck at 45 (of 60 litres). This applies to both an analogue gau...

I have an MX1 but assume it's a similar process: Calibration values need to be set for various levels of fuel within the EFIS menu, so likewise in the simulated version. The values are raw data numbers from the A/D conversion on the fuel level inputs. It's not clear what the value units are in terms...
