I am thinking of changing over to a vanity call sign and I understand the process for that, but what I am having trouble with is what do I do when calling out on say 2M to those who already know my current call sign or those who may have only heard me a few times. Is there a set amount of time that you use both of them or do you just switch cold turkey and then let people know that you switched? I have tried looking this up, but just keep getting the same old "go hear to change signs" nonsense. So what is the protocol when doing this? Thanks!
