I am getting ready to get setup to use LoTW. Since I have had three different calls since 1977 I suppose that I will need to apply for three different certificates in LoTW? I know the dates of when each call started and stopped, so it won't be too difficult for me to sort out my log and upload it. Anyone have any tips with LoTW? Scott, K8SM (ex-WD8NSD, AA8SM)
