For radio amateurs seeking to verify contacts or identify stations from Tajikistan, the _Tajikistan EY Callbook_ serves as a dedicated online resource. This callbook, compiled and maintained by Irage M. Tursoon-Zadeh, _EY8WW_, offers a focused database of callsigns within the EY prefix region. It provides a practical utility for DXers and contesters aiming to confirm QSLs or prepare for operations involving stations in this specific geographic area, streamlining the process of identifying active hams.
