To all: Caution when you add/modify a Mapped Prefix in the Call Map or Alias Map tables..
The meaning of the column "Old1 Date" is "Equal or Less than this DATE" So, in the case of the addition of KH8S (Swains Island) to the Alias Map table, the entries should be as follows: Map PFX = KH8S Pri PFX = KH8S Old1 PFX = KH8 Old1 Date = 07-21-2006 So, also, in the case of the addition of YU6 (Montenegro) to the Alias Map table, the entries should be as follows: Map PFX = YU6 Pri PFX = YU6 Old1 PFX = YU Old1 Date = 06-27-2006 In each of the above examples - the ARRL has stated that: Therefore, effective June 28, 2006 (UTC), ARRL has added The Republic of Montenegro to the DXCC List. and -- QSOs made with Swains Island on or after 0001Z, July 22, 2006 will count for DXCC credit. As can be seen, the Old1 Date column reflect the "previous" DAY - as compared to the "effective date".. This setup can be checked out by making the entries (as shown above) - and then make 2 entries for each of the entities -- one will be Swains Island example: 07-21-2006 2359 KH8SI and hit TAB .. you will see that this entry gives the Prefix of KH8 then -- 07-22-2006 0001 KH8SI and hit TAB .. now, this entry gives the Prefix of KH8S 73 Joe wa6axe
