DIY Rig control CI-V Cable for Icom Transreceiver.

Hello, every one this is VU3EFL.

After making 20/40 meter antenna for my icom transreceiver 746pro, I plan to make DIY CI-V Cable to control my rig using my Desktop pc.

For controling rig we need FTDI USB Icom programing cable, You have a option to buy new one from the online market place. But as a hobby i always try to make it by my self so that it saves money, enhance knowledge and when its works – “Give confidence and feeling of satisfaction” that yes i make it and its works :P.

I made DIY rig control cable in just About ~3$ only (INR.200 only).

So lets come to the points.

Things Needed :

  1. FT232RL – USB to TTL Converter/ Adaptor : For India – You can buy from online USB TO UART TTL 5V 3.3V FT232RL It’s just cost me Rs.130 only (~2$).
