There are two distinct operators lists available to serve you:
Roger, VE7VV, maintains a list detailing North American stations that we are aware of having completed at least one two-way QSO on 630-meters and / or 2200-meters, regardless of mode. That list can be viewed here.
Ralph, W0RPK, maintains a WORKED-ALL-STATES list of US stations that are willing to complete two-way QSO’s AND QSL for future WAS awards. That list can be accessed here.
Note: The WAS link is not static and is updated regularly so beware if linking to it. It’s best to link to the parent post if embedding.
