Good night!. My name is Federico (LU1XCF) I am writing to you from Rio Gallegos - Argentina. The information that I am seeing on this site is very interesting and very useful. I came here trying to gather information about the programming of the Icom ic 751's RAM board, only the board that belongs to a 751 came to the laboratory, which lost all functions due to the battery being desoldered from the board. I built the interface to be able to record the card again, use the diagram mentioned by The Radio Shop and use the ICOM-RAM.EXE program, I tried it with windows XP SP 2 and with Free DOS without obtaining results. Could you tell me if ICOM-RAM.EXE worked for you? Since already very grateful for the information. I remain at your disposal ..
