ICOMPROM ICOM Non-Volatile RAM Module

I installed the Icom Non -Volatile Ram Module in my 745 . I had to change some jumpers on the board as per instructions .I said a little prayer, turned the rig on and Bam , works like a charm . This is the second product that I have bought from these folks with great results ,the other was a tone board for my Yaesu 736r . Thanks once again , Fred Lawson AD4HG
