WAC endorsements

Earl Needham

Can I ask a question about WAC here?

I have the WAC application in front of me, and at the top it shows the following awards available:

Basic, CW, Phone, Image, Digital, and Satellite.

It also shows the following endorsements available:

QRP, 1.8, 3.5, 50, 144, 432, 1296, and OTHER ENDORSEMENTS.

What are those "other endorsements"?  I can guess five-band would be one, and maybe eight-band, but are there others?
