Breaking the radio squelch would not make it more difficult to hear incoming radio
transmissions. The symptoms that you describe are from breaking the intercom
squelch. The white noise is cockpit noise. As the engine RPM increases,
the cockpit noise increases until it reaches a point where the intercom squelch
is broken. Try adjusting the intercom squelch at cruise RPM using the large
knobs, left knob for pilot and right knob for copilot.

Hi Joe,
Thanks for your suggestion. What you say makes perfect sense. I tried
turning up the pilot intercom squelch before but I may have inadvertently
left the copilot squelch low and the copilot headset connected. I'll check
that next time I'm in the plane.

Haven't decided. I must acknowledge a level
of risk for removing a component that really
DID have some value at some point in time.
But without seeing the numbers and understanding
the idea behind the capacitor's original
inclusion, I'm not prepared to offer any
blanket opinion. But it will be the topic of
a future study wherein there is a high probability
of discovery of the capacitor's no-value-added
existence.
I'm aware of no potential for adverse effects
so don't rush out and remove any that are already
installed . . .

I have had an in flight fuel starvation event that was not resolved until after
a no power landing which was successful. I know from that experience that
a fog of confusion came over me and after replaying the event in my mind, I could
not recall the point that the aux fuel pump was turned on. I had been through
the drill many times to simulate an engine out emergency but I know for
me when it actually happened, I did not perform as well as I could/should have.
An automatic switching to the aux fuel pump could potentially take care of
a problem without me having to remember to do it in the event of the fog. Of
course I would want some indication of the switch occurring.

Ed,
I had suggested a similar "foolproof" system to Bob N when installing my EFI system.
And he responded the same as he responded to you. What benefit is there
to have the system be "automatic"? When I thought about it, I had to conclude
that it just seemed cool. So, with that, laziness kicked in and I found a sense
of relief that I didn't have to figure out another sub-system for my one-off
Glasair/Franklin CDI ignition, EFI, installation.
Then on first flight/take-off, I had an engine sputtering at 800'. Because I was
in the TO phase, TO/
