Complete Home Brew DV adapter V01.04

Note
I have less 20 boards now. (19 April 2009) If you are interesting this PCB, please contact me. I distribute PCB only.Sold Out!

Currently I do not make extra PCB yet. Because I ordered AMBE2020 and CMX589A chips to Fred (PA4YBR) last December. I sent about 720 euro to him. But I did not get it yet. So, I do not have extra money for making PCBs. (I am not ham shop and maker. I make it with my pocket money. Sorry All) 07 June 2009

This PCB does not include "Callsing entry system", "Callsign display system" and "audio PA system".

USB connector was changed from A type to B type. Diagram of this PCB is V01.04. The detail information of this PCB is on new URL. When you will order this PCB, I will tell you new URL.

    This PCB has one mistake. I forgot to float the pin one of VR1. If you will make this, please do not connect the pin one of VR1. (see red circle.)

    This pcb needs about 70mA of 5V. Please connect USB or 5V(with Voltage Regulator).

    This PCB uses the PICkit2 for programing of PIC18LF4550.

    Connect (header pins) for PICkit2 (see red circle.)

    Detail Information.
    SW1:
    ON when COS circuit is open colector without pull up registor,
    OFF when COS circuit is ont open colector or with pull up register.
    SW3:
    1-2 (must be SW2 OFF) when COS is reversed signal.
    2-3 and SW2 ON when COS is normal signal.


    Mod. Information
    Mic noise
    Some PC is caused the noise (low frequency) on trasimmitted signal. If you catched it, please added R30 and C34.
    See red circle.


    CMX589 lock program
    When you use IC-91AD(Japanese version is ID-91), node adapter does not work. Pleas add 1M to pin 13 and 14 of CMX589AP4.
    See red circle.


    Increase Mic gain

    remove R13.


    Changed C7 from 4.7uF to 47uF.

    Increase TX level
    If your IC-91AD does not decode the callsign, please increase the value of R8. (from 100K to 500K/510K)
