Dave Welcome to the group and have always appreciated the help from Artek. If only frequency no need to care about the date. I learned this from fellow time nuts. Yes I also hate 1996. Now I think there are later software releases. I haven't had my 3801 on for a bit as I discovered that I actually have a jumping frequency issue. But If need be happy to copy the software. Also check KO4bbs website later eproms may be there. I don't actually recall seeing eproms in the unit. Up until recently my 3801 of 10-14 years just worked thats why I am unclear about the internals. Unfortunately seems I may be digging into it. Regards Paul. WB8TSL
