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. The resource's utility is particularly evident for those engaged in award programs like _DXCC_ or _WAZ_ where accurate callsign verification is crucial for credit. Unlike broader, worldwide callbooks, this specialized listing ensures high relevance and accuracy for its target region, reflecting the local expertise of EY8WW. Its direct focus on Tajikistan makes it a valuable, albeit niche, tool for operators with specific interest in Central Asian DX.

KB9AMG's Top WSPR Spots presents a focused online tool for monitoring **2-way WSPR reports**, specifically detailing propagation data from February 2026 through March 2026. This resource aggregates _WSPRnet_ data, allowing radio amateurs to observe weak signal propagation conditions across various bands. The interface is straightforward, presenting callsigns, frequencies, signal-to-noise ratios, and distances for each reported contact, which is crucial for understanding current band openings and signal paths. The utility of this WSPR spotter lies in its ability to quickly visualize global propagation. Users can identify active stations and assess signal viability over long distances, with reports often showing contacts spanning thousands of kilometers. For instance, a typical WSPR report might indicate a signal from Europe reaching North America with a _SNR_ of -25 dB, demonstrating effective low-power communication. This data is invaluable for planning DX operations or evaluating antenna performance under actual propagation conditions.
