Same here, my birdie shows S3 with antenna disconnected, so the equivalent
of about one microvolt if it was a signal at the antenna terminals. You need
a quiet band to hear this level. My 80M band is never that quiet.

Just tuning around a bit with antenna disconnected and found these potential
additional birdies. Definitely not an exhaustive search...Most are not
audible over band noise with an antenna connected.
