From the WAZ Zone/Country List in the WAZ rules below: http://www.cq-amateur-radio.com/wazrules.html Zone 23. Central Zone of Asia: JT (Mongolia), UA0Y, BY3G-L (NeiMenggu), BY9G-L (GanSu), BY9M-R (NingXia), BY9S-Z (QingHai) and BY0. I believe the only z23 station recently active is UA0YAY (no UA9s are in z23). K4ZW may have some comments about JT1CO. 73, Bill W4ZV
