[amsat-bb] LVB Tracker reset problem

Got my LVB Tracker from AMSAT last week. Installed it on a G5500. Calibrated it and it seemed to work fine until yesterday. It seem to now just randomly reset itself as if it were being power cycled. The LCD screen posts the startup firmware version message then goes back to normal. This happens randomly. I have opened up the unit ad everything seems to be seated well. Any suggestions on where to look? Could this be a voltage issue from the G5500 or out of the voltage regulator on the LVB. When this happens it locks the virtual comm port on the computer causing me to have to reset the rotor & tracking programs.

Thanks, Bill - W4RVN
