Analyzing a decade of contest operations and QSLing from March 1993 to March 2003, K5ZD presents data on QSO totals by band and mode, QSL error rates, and DXCC progress. The article details the author's methodology of only answering incoming QSLs, which allowed for a study of call copying error rates, found to be between 0.8% and 1.7%. These error rates correlate with typical contest log checking reports (UBN/LCR). The data also tracks the percentage of QSOs confirmed by QSL cards annually, averaging 12.1% over the ten-year period, with a steady rate of 14-15% in earlier years. Specific statistics include a total of 215,653 QSOs logged, with 26,184 QSLs received. The article identifies the top 33 countries for incoming QSLs, accounting for over 87% of the total, with Japan, Germany, Spain, and Belgium being prominent. It also touches upon the potential of ARRL's Logbook of the World (LoTW) for instant confirmations, while noting potential error rate implications. The author's station, initially a barefoot setup with a Hygain multi-band vertical, evolved into a fully operational contest station by October 1993, utilizing DX4WIN for logging.

The Receiver Test Data resource is a detailed review database focusing on the performance metrics of various radio receivers. The methodology involves rigorous lab measurements, often adhering to standards such as the ARRL RMDR (Reciprocal Mixing Dynamic Range) and BDR (Blocking Dynamic Range). Specific test equipment and protocols are utilized to assess parameters like noise floor (dBm), AGC threshold (uV), and LO noise (dBc/Hz). For example, the _Icom IC-7300_ is evaluated with a noise floor of **-133 dBm** and an LO noise of **-141 dBc/Hz**, providing insights into its performance under different operational conditions. The resource includes a wide range of models, from the _Elecraft K3S_ to the _Yaesu FTdx-101D_, each tested for dynamic range, sensitivity, and selectivity. The data is sorted by key metrics such as third-order dynamic range and phase noise limitations, with RMDR values calculated by subtracting 27 dB from LO noise figures. This structured approach allows users to compare different receivers' capabilities, focusing on technical specifications and performance outcomes in various scenarios.
