The Kenwood TH-F6A handheld transceiver can achieve an extended transmit frequency range of 137-174 MHz, 216-235 MHz, and 410-470 MHz by removing a specific diode and chip resistor from the main PCB. This modification also expands the receive range on the A-band to 142-152 MHz, 216-235 MHz, and 420-450 MHz. For the TH-F7E, the transmit range extends to 137-174 MHz and 410-470 MHz, with a corresponding receive range on the A-band. Performing these hardware changes will reset and initialize the radio's memory contents, necessitating prior backup of important channel frequencies. Instructions are provided for constructing a homemade PC programming cable compatible with the Kenwood TH-G71A, TH-F6A, and TH-F7E. The interface utilizes an RS-232-to-logic (0-3.3V) level-shifter and a full-duplex serial connection, adapting the Kenwood PG-4S cable schematic for the TH-G71's 2.5mm and 3.5mm phono plugs. Specific schematic tweaks include changing R1 from 150 ohms to 1K ohm to optimize power from the serial port and adding a 150K ohm resistor between the Radio TXD and ground to manage the 3.3V I/O pin. Detailed plug pinouts for the 2.5mm and 3.5mm connectors are presented, with the interface's TXD connecting to the ring of the 2.5mm plug and RxD to the shield of the 3.5mm plug. Ground connects to the shield of the 2.5mm plug, while the tips of both plugs are no-connects. Debugging procedures cover verifying positive and negative power rails from the serial port, checking component polarities, and testing level-shifting and inversion functions of the interface. Software setup involves enabling "TC ON" (Menu 15 for TH-G71, Menu 9 for TH-F6) and using Kenwood's MCP programming software.

The **ARRL Contest Calendar** presents a detailed schedule of upcoming amateur radio competitions, encompassing both ARRL-sponsored events and significant non-ARRL contests. It provides essential operational details for each entry, such as specific operating periods, eligible bands, and permitted modes, enabling contesters to plan their participation effectively. The resource also links to official rules, soapbox reports, and QST results, offering a comprehensive overview of past and future contest activity. Users can navigate through monthly listings to identify contests of interest, with direct access to detailed information pages for each event. The calendar serves as a central hub for contest operators seeking to confirm dates, understand exchange requirements, and review post-contest analyses. Its utility extends to both seasoned contesters and those new to competitive operating, providing a structured approach to contest participation. The platform integrates various contest-related resources, including links to **Contest Corral** entries for non-ARRL events, ensuring a broad scope of coverage. This aggregation of information streamlines the process of finding contest schedules and associated documentation, making it a practical tool for the amateur radio contesting community.

The FTBVR5K software facilitates comprehensive memory management for the Yaesu VR-5000 scanning receiver, supporting operations such as modifying, moving, adding, deleting, masking, and unmasking individual memories. It allows for importing and exporting memory definitions via CSV files, sorting memories by frequency or name, and identifying duplicate frequencies within the receiver's configuration. The program also supports the creation and modification of bank definitions, management of PMS (Programmable Memory Scan) definitions, and adjustment of PMS scanning ranges. Additionally, users can print detailed reports of memories, banks, PMS definitions, rig settings, and S.CALL details, with visual cues like red highlighting for masked memories and yellow for the priority channel. FTBVR5K provides functionality to alter values within the VR-5000's Set and Config menus, and to change S.CALL station names and frequencies. The application operates on standard Windows PCs, including Windows XP, Vista, 7, 8, and 10, requiring an available COM port for transceiver connection, which can be a conventional serial port or a USB adapter. A minimum screen resolution of 800 x 600 is supported, with 1024 x 768 recommended for optimal usability.

N3FJP's ARRL Field Day Contest Log 6.6.10 is a dedicated software solution for Windows 7 through Windows 11, specifically tailored for the annual ARRL Field Day event in June. This program provides essential contesting features such as duplicate checking, including partials, and a dynamic list of sections that change color upon being worked. It seamlessly interfaces with popular digital mode software like WSJT-X, Fldigi, and JTAlert via API, and supports rig control for most Elecraft, Icom, Kenwood, and Yaesu transceivers. The software also generates computer-generated CW via serial port or Winkeyer, plays wave files, and offers DX spotting capabilities. Operators can leverage its fully networkable design to allow multiple PCs to update a single log file simultaneously, enhancing club operations during Field Day. The program outputs ASCII log, dupe, and summary files for contest submission and provides real-time statistics. A quick start video is available to guide new users through the basics of the software. Registration for permanent use costs $8.99, or it can be obtained as part of the N3FJP Software Package, which includes over one hundred amateur radio programs for a one-time fee of $59.99.
