The DXXE Group was created in January 2005 by Mexican radio amateurs that share a passion for DX, contests, expeditions and island activations.

The W0IS resource outlines methods for finding historical US amateur radio call signs, particularly for genealogical research. It highlights the comprehensive collection of digitized call books from 1906-1996 available at leehite.org, stored as searchable PDF files. These resources significantly simplify what was previously a laborious manual search through physical call books, which were typically indexed by call sign rather than name. The guide details specific search techniques for various eras. For early radio days (1913-1923), government call books are readily available and searchable online via Google Books and hathitrust.org. For the period between the 1930s and 1980s, when private publishers like "Radio Amateur Call Book Magazine" dominated, the resource points to archive.org for scanned editions (1938, 1940, 1948, 1972) that support full-text OCR searches, despite potential scanning errors requiring flexible search terms. It also provides strategies for navigating Google Books' "snippet view" for the 1952 call book, including searching by name or address and interpreting often illegible snippets. The resource suggests cross-referencing findings with hamcall.net for call sign verification from 1921, 1954, 1960, 1969, and 1983 onwards. Additionally, it lists physical call book collections at institutions like the Pavek Museum of Broadcasting and individuals like W3HF, offering avenues for deeper research when digital methods fall short.

The **LDG Z100 Autotuner** review by GW6ITJ details the unit's practical application and performance in a ham shack environment. Initially acquired to replace an MFJ-902, the Z100 is noted for its ease of use, though the author observes it doesn't quite match the impedance range of the older MFJ unit. This hands-on assessment provides a real-world perspective on its capabilities for 100-watt operation across the HF bands. GW6ITJ specifically mentions the Z100's suitability for 3.5 MHz and higher frequencies, indicating its utility for common HF operations. The review focuses on user experience rather than technical specifications, directing readers to the LDG website for detailed data and manuals. This approach highlights the tuner's operational characteristics from a user's perspective. The author's experience with the Z100 suggests it's a reliable choice for general amateur radio use, particularly for those seeking a straightforward autotuner. The comparison to the MFJ-902 offers a valuable benchmark for hams considering a similar upgrade or new acquisition, emphasizing practical differences in impedance matching.
