[chirp_users] 91-A with 121 - B bank is fine - A bank does not work

I am sure someone has asked this question but here goes anyway. I purchased a 91-AD and have programmed it's memory banks A and B. I then purchase a 91-A with a 121 chip.. While it was possible to get my B bank into my B bank I am unable to make an excel file of my A bank to get it into my A bank on the 91-A. Is there some way around this or is there a way to print out what is in the A bank on the 91-AD and put it into my excel spread sheet and then export that into my 91-A using CHIRP? Thanks for a great program - at least my "B" bank information transferred over. 73- N3AOQ Roger
