Hi Dave,
You don'thave to connect the via points to the ground.
Ground connections go on the other side of the capacitors and buttons.
In other words, the capacitor is connected in parallel to the button. One side to the via point and the other to the ground.
When you connect ground to the via points, rb1 and rb2 are activated all the time.?

Subject: [ATU100] Tuner always in Test Mode
Hello,
When I only had the tune button connected, the tuner started up in a normal mode.
Now that I have added the auto and bypass buttons, it always starts in test mode. I have the caps connected across the switch terminals with one terminal connected to ground, and the other connected to either RB1 or RB2 on the board. I then have a wire from both vias on the board connected to ground. Does this sound correct, need more info, etc?
Any and all feedback is welcome.
Thanks & 73,
Dave KC3GPM?
