670 (ID), 720 (NV or ID, went to NV), 780 (NV), 880 (NE), 890 (UT), 1020 
(NM), 1030 (WY), 1100 (CO), 1120 (CA or OR, went to OR), 1180 (MT), 1210 
(OK).

1965 was the earliest (1020); 1980 was the latest (890).

Since "Rio" MANY Class I-Ns have been added to Alaska [ * ] ... on both 
US Class I-A and on US Class I-B channels.

Class I-Ns are NOT required to meet the minimum efficiency requirements 
for Class I stations.

Also since "Rio" any Clear, domestic or foreign, with exceptions, may be 
used domestically for Class B stations.


[ * ] Alaska, therefore, becomes the state with the most Class As, of ANY 
U.S. state, Canadian province, or Mexican state.
