Transponder problems with ATC COMS - Video

You are right, Xponder is not a serious problem in our situation. We
didn't consider it a serious problem or we wouldn't have left KMBO.

It **could have been** a more serious problem had we been inside
Charlie or Bravo airspace.

I've had a mode C failure inside the SFO Bravo surface area. I
was northbound along 101 for the Bay Tour at 3500ft. ATC let me
continue, but had me maintain 2000ft for my tour (normally, as long
as you stay outside the Bravo, they dont't care about your altitude).
After the tour, I was cleared through the Bravo again for the return
to PAO. The only issue was PAO tower was a bit miffed that my mode
C was out, but NorCal didn't have a problem with it across several
controllers.

Was it a complete failure or reporting incorrectly and they had you
stop mode C?

Just curious to see if it was reporting incorrectly and lack of
knowlege on turning mode C off as it was in my situation, do you think
they would have cleared you through Bravo?

It was intermitently working, and reporting incorrectly, IIRC. They
just had me stop mode C.

Not sure what they would have done in that case. I know Norcal can
see primary targets (no transponder), so they might just have had
me turn it off at that point.
