My QMX went up in smoke at my initial power up.? One of the voltage regulators on the buck power board blew.
Prior to that, I was able to download the firmware using a 9v smoke detector battery for power. Afterward, I got that row of boxes, indicating that the processor had not booted.? The fatal error was connecting my 12v supply (3ah LiFePo4 battery) which precipitated the failure.
I have no way of knowing whether anything beyond the buck power board was damaged.
I'm throwing in the towel on this one. I successfully built 4 QCX units that worked, but this one is beyond me.? Despite a 3x magnifier headset, I was not able to find any solder bridges or faulty connections. My eyes are getting too old. And I don't have the electronics background to troubleshoot it.
Anyway, the remains of this QMX are offered to anyone who would like it. I ask only for shipping reimbursement. $10 will do it.? This offer does NOT include the enclosure as I hope to get a factory built unit if and when the backlog ever decreases. (It was at 770 builds yesterday.)
My QRZ contact info is good.
