[arm-allstar] RPi3 LEDs acting weird

You said the red LED was on and steady, then you said after changing the power supply, the red LED is rock solid.
My red LED is constant on, so does that mean it's low on voltage or has good voltage? Should the red LED be off?

The solution to my blinking LED ... As always Doug you were right...Power Supply.
I was using my bench supply while building a few new Pi nodes.
Supposedly it has more than enough current. I Had checked the Voltage many times and was always set for 5.15 V out when feeding the Pi3. Current regulation must be flaky as the Pi's Red LED would stay on steady whenever the USB FOB ptt was active and passing audio.
Solution was to drag out one of the Ebay Chinese 12 volt to 5 volt 3 amp converter and hook it to 12 volts from the bench supply.
Flip the switch and the Pi3 Red LED is rock solid.
Love those little ebay converters. For the price you can't go wrong.
