Title: Reprogramming a Icon IC-745 ram board
Post by: Radio Tech on December 10, 2017, 03:43:20 PM
This is a project I will be working on. There were several DOS base programmers made to read and write the content of the ram boards for the 745 and 751 radios.
The problem is they were all DOS base and used the computers printer port to send and receive data.

What I like to do is come up with a USB based programmer to do the same.

I will be adding lots of files and pictures to this thread over the next few days.

Followed along on the EEVblog and saw that you were successful in duplicating the 745 ram board.
Will you be making these and have them available for general purchase or only for use in radios that come into the shop?

Regards.
