This resource provides a historical analysis of amateur radio call sign assignment policies in the United States, detailing regulatory shifts from the Department of Commerce to the Federal Radio Commission (FRC) and subsequently the Federal Communications Commission (FCC). It documents the evolution of call sign issuance, from early reissuance practices in the 1920s to the implementation of the Group Call Sign Assignment System on March 24, 1978. This system categorized call signs (e.g., 1x2, 2x1, 1x3, 2x3 formats) into groups A, B, C, and D, correlating with license classes such as Extra, Advanced, General, and Novice, and specifying prefixes for contiguous U.S. and territorial areas (e.g., _AH_, _KP_, _KL_). The document further details the legislative process leading to the modern Vanity Call Sign program, initiated by a petition in June 1990 and formalized by the Omnibus Budget Reconciliation Act of August 10, 1993. It outlines the FCC's adoption of final rules on December 23, 1994, and the subsequent fee structure, with the first vanity call sign issued on May 31, 1996, at a cost of **$30.00** for a ten-year term. The ARRL's proposed "starting gates" implementation strategy is also described, which phased in eligibility for vanity call signs based on license class and prior holder status.

PSK Reporter,is a powerful tool for monitoring your FT8, JT65 or PSK signals around the world. But, even if you are not transmitting on any of these modes it can still be a great propagation tool for determining which bands are open and to where in the world signals from your area are being heard.

This is a compact three transistor regenerative general coverage receiver with fixed feedback. The sensitivity and selectivity is relative good, especially on the LF and MW bands, as can be expected with this simple design.
