The ZS6BKW multiband antenna, an optimized variant of the classic G5RV, features a 102-foot (31.1 m) horizontal span and a 39.1-foot ladder line matching section. This design, derived by G0GSF (formerly ZS6BKW) in the early 1980s using computer programs and _Smith charts_, aims for improved SWR across multiple HF bands compared to its predecessor. Construction details specify Wireman 554 ladder line and #14 AWG THHN copper wire for the radiators, with precise instructions for determining the velocity factor (VF) of the ladder line using an antenna analyzer or dip meter, ensuring accurate physical length for the matching section. The radiator length is electrically 1.35 wavelengths for the 20-meter band, requiring careful trimming during tuning. Field measurements with an _AIM-4170C_ analyzer by KI4PMI and NC4FB demonstrated good SWR curves and bandwidth on 6, 10, 12, 17, 20, and 40 meters. The antenna was deemed unusable on 15 and 30 meters due to very high SWR, but an LDG AT-100PRO autotuner successfully brought 6 and 80 meters into tune. Contacts were made on 80, 40, 20, and 17 meters, including a **17-meter** contact to Spain. EZNEC models for 80-6 meters are provided, along with an AutoEZ model by AC6LA, which predicted good SWR for 80-10 meters. W5DXP's modifications for an all-band HF ZS6BKW are also referenced.

Spanish web site

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.

A C-Pole Antenna for QRPxpeditions describes a DIY C-Pole antenna designed for QRP (low-power) expeditions, inspired by KF2YN’s ground-independent vertical model. After adjustments, it achieved a 1:1 SWR at 14.060 MHz, rising to 2.5:1 at 14.35 MHz. A choke balun, comprising 15 turns of RG8X around a 4” can, was essential for optimal performance. Compact and self-supporting, the antenna enables reliable communication with minimal setup. Contacts included stations across the U.S., and even a 4,600-mile connection to Spain using only 5 watts.
