The ARRL Logbook of the World has now added the ability to confirm, track, and obtain VUCC on all bands from 50mhz and up. This is a feature that has been a long time in coming, and should be a nice perk for those working VHF/UHF/SHF frequencies to help obtain the VUCC awards. Additionally, they included the coveted Fred Fish Award in the system as well.
Log into your LOTW account, select AWARDS, and click the 'Create New VUCC Award Account' button. You must set one rule for it to work, and it'll walk you through that. If you have been operating from the same location, or locations within the 200km requirement of the ARRL, simply choose "Call Sign" and it'll do the rest.
If you're not on LOTW, sign up at https://p1k.arrl.org/lotwuser/default . You can simply upload your files from your currentl logging program in ADIF format (most all logs export in that format), and you'll be in business. Another perk of doing this is it provides an online backup of your logs, in case you have a computer crash.
