I've had a senior moment here. Someone earlier today mentioned that in order to work 60 mtrs legally you needed the TCXO and then you needed to change menu 5-9 to 2.4. It's default is 6. Now why do I have to do this? I have the TCXO and it is installed and I changed 5-9 from 6 to 2.4, but why? Also what effect does it have on other bands/modes? Bob KB4CL
