CwType v2.35 provides a dedicated terminal interface for **CW operators**, facilitating Morse code transmission from a Windows PC. Users can input characters via the keyboard or a connected paddle, supporting iambic keying. The software manages transceiver control, including PTT and CW keying, through COM or LPT ports. It offers adjustable speed, dash/dot ratio, and inter-letter spacing, with real-time speed display in LPM and WPM calculated by the "PARIS" method. The program includes features like MOX mode for automatic TX on/off, configurable weighting to compensate for transceiver element clipping, and programmable F-key macros for sending predefined text or special sequences. CwType can integrate with logging software such as AALog (V1.0.3 and later) for data transfer, and supports various character sets including English, Russian, and Swedish. A beacon mode is also available, executing the Alt-F12 macro periodically at a user-defined interval. Audio output for monitoring can be routed through the internal PC speaker or a sound card, with options for sine waveform and smooth envelope generation for SSB transmitters. The software is compatible with **Windows XP/Vista/7/8/10** and is distributed as freeware.

This resource details the computer-optimized design of the _ZS6BKW_ multiband dipole, an evolution of the classic _G5RV_ antenna. It begins by referencing the original 1958 RSGB Bulletin article by Louis Varney G5RV, explaining the operational principles of the G5RV's flat-top and open-wire feedline on 20m and 40m, noting its impedance transformation characteristics for valve amplifiers of that era. The article then transitions to the rationale for optimizing the design for contemporary solid-state transceivers requiring a 50 Ohm match. The core of the project involves using computer modeling to determine optimal lengths for the flat-top and matching section, aiming for a VSWR of less than 2:1 on multiple HF bands. It discusses the process of calculating feedpoint impedance based on antenna length and frequency, referencing professional literature from Professor R.W.P. King at Harvard University. The analysis also considers the characteristic impedance (Z(O)) of the open-wire line, identifying a broad peak of adequate values between 275 and 400 Ohms. Specific design parameters for the improved ZS6BKW are presented, including a shorter flat-top and a longer matching section compared to the original G5RV, with a velocity factor of 0.85 for the 300 Ohm tape. The article confirms acceptable matches on 7, 14, 18, 24, and 28 MHz bands when erected horizontally at 13m, and also discusses performance in an inverted-V configuration, noting frequency shifts. The author, Brian Austin ZS6BKW, emphasizes the antenna's suitability for modern 50 Ohm coaxial cable without a balun.

A 7 MHz vertical half-Moxon array, designed by F6IRF, is presented with its MMANA model, featuring a 20cm gap between the two horizontal elements. The design aims for a low take-off angle, crucial for DX work, and includes specific dimensions for the driven element and reflector, which are constructed from 2mm copper wire. The antenna's feedpoint impedance is approximately 50 ohms, allowing for direct coax feed without a matching network, and it is intended for portable or temporary installations. Field results indicate the antenna provides a **3 dB** gain over a quarter-wave vertical, with a front-to-back ratio of **10 dB** on 40 meters. The author notes successful DX contacts into _VK_ and _ZL_ from France, demonstrating its effectiveness for long-haul communication. The design emphasizes simplicity and portability, making it suitable for operators seeking a directional antenna solution for the 40m band without complex setup requirements.
