Subject: ICOM ICF-5023H programming software & cable link

Post:

Hi everyone,

I’ve seen a few people asking for the programming software link for the Icom ICF-5023H (VHF marine transceiver). After searching, here’s what you actually need:

1. Official Software – CS-5023
Icom does not offer a free public download link for this software. It’s typically distributed to dealers or via a paid Icom programming CD.

  • Part number: CS-5023 (often called "Cloning Software")
  • Source: Contact an Icom dealer or Icom America/Japan support directly. They may email it upon proof of ownership.

2. Third-party option (often easier)
Some users have success with RT Systems software, though check their site for ICF-5023H compatibility first.

3. Programming cable
The radio uses a CT-17 (or compatible) cloning cable.

  • Icom original: OPC-478 (or OPC-478UC)
  • Generic alternative: Search eBay/Amazon for "Icom OPC-478 programming cable" (~$15–25)

4. Direct download leads (no virus links)
❌ Avoid random “free software” sites – many are fake or infected.
✅ Try the Icom Japan Global Support page → go to “Downloads” → search “CS-5023” (login may be required).

Final tip:
This model is not USB-ready. You will need a real COM port (or a good USB-to-serial adapter like FTDI chipset) with the OPC-478 cable.

Hope this saves you time. If you already have the software and need the .icf file structure, let me know.
