I read that some of you go from 2.062a back to 1.373b5 and so forth. (I have not done the hardware change to go to version 2 yet-mainly because of the difficulties I read on here.) Question: Do you have to un-do the hardware changes to go back to an older version-like 1.373b5-from a newer version such as 2.062b? 73, Dave KE7GI
