Hi, I'm Harold, my ham radio call sign --> "KE6JMG", I develop PCB designs, embedded firmware, and  interface control software.  If you need help with your next design, or need a new PCB design, please send an email, and I'll try to help you with your MICRO, CPLD, DSP, or FPGA pcb.  I specialize in prototype development, interface circuitry for new digital designs, RF instrument programming for automated test manufacturing. Also Audio Precision test equipment programming in the environment for new audio circuitry needing verification and evaluation for manufacturing.
