I just fired up my IC-7610 with coax connected to LA-1K (running on 120 VAC), followed by coax connected HF-Auto tuner.
Antenna was not connected to the HF-Auto for this test (left open).
I tuned across 20 meters without seeing anything - no birdies.
Guess I wouldn't be surprised if the display put out a bit of close-up interference - just for fun, try changing the backlight settings.
