I have just sent a new batch of QSLs via GlobalQSL for printing and distributing via the bureau. I like the Global QSL service. It takes away the chore of sending QSL cards and reduces the work to a simple log export to ADIF file.
I had to purchase 1000 new card credits before I could upload them. Today's batch, from last summer until now, was over 400 contacts on 398 cards. That's excluding local FM QSOs and contest contacts. I didn't realize I was so active on the air. At that rate I'll be ordering another batch before the year is out!
