Hi Guys , hope this programming software is useful to some people, it's software I got from Icom pro400 Forum many years ago now which I found useful, eg setup a password buttons on the face of radio , having private channels on the side and listing to Emergency Services that are still using UHF .
Connect link cables you can be found on Ebay around $25 buck. regards Alex
p.s. : must use serial number that in zip file under the heading "Code"
