model variations
quote "Generally, prior to the 8G05 production run, there was one main problem in the design of the radio: it only had unidirectional CAT control for frequency and mode (i.e., you could only use the PC to command the rig but not to report the rig frequency and mode back to the software on the PC). Beginning with production run 8G05, the radios have bidirectional CAT for frequency and mode (PC commanding the rig, and the rig reporting information to the PC). In the USA (at least), Yaesu offered to upgrade all radios older than 8G05xxxx under warranty, which involved replacing a computer chip in the radio and some other modifications. Many people with earlier rigs took Yaesu up on their offer." , source.
