It was recently discovered that the Open Collector outputs were not as previously
documented. This only affects the G2.

WARNING!!!!
Those who have your HF amplifier connected to the G2 Via DB9 Open Collector port on the back of the radio for Band Switching control make sure if you update your radio software/firmware you check that your amp is switching to correct bands or MAJOR damage to your amplifier could possibly occur!!

If you update your radio and it switches to the incorrect bands you will have to make a new amplifier control cable for the NEW pinout change with the G2.
