I tried looking through release notes and the forum and didn't see anything specific here. This may be a stupid question, but I feel like I am having more success making contacts with 2.1.2 than I am with 2.2.1 and am wondering if that's because 2.2.1 won't work with stations still using 2.1.2 or older? I know one of the big enhancements was the timing so thought maybe that had something to do with it. Thanks for any info and all the work that is done on this software and technology, it's amazing.
