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.

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.
