Icom OPC-478 Connector

Info for this Connector was obtained from ICOM CI-V Hardware Page

Here are some images of the OPC478 connector someone is making for me.

Icom OPC-478 Interface.

The ICOM design for the OPC-478 interface is a simple transistor circuit used for cloning. The version by Chris VK3JEG http://uk.geocities.com/blakkekatte/hardware/opc-aus.jpg gives equivalents for the transistor and diode parts. That version is the one commonly found on the internet. However the one from ICOM Japan’s site http://uk.geocities.com/blakkekatte/hardware/opc478-japan.jpg has a few modifications. I have added the transistor and diode equivalences from VK3JEG’s copy of the earlier version of the interface. WA0SXV http://www.wa0sxv.us/ci-v.html has some reservations that this design might not properly implement the RS-232 protocol.

    Please note that the Photo has jumpers set for another Icom, not IC-E90 as was being tested at the time, and one of the circuit diagrams was an earlier version, so be careful if you use.

    I am curious if a parts list and assembled kits are available for this schematic?
