The resource provides a specific wiring schema for adapting a Kenwood PG-4S cable to be compatible with Kenwood TH-F6A, TH-F7E, and TH-G71 handheld transceivers. It details the necessary pinout modifications, illustrating how to convert the existing PG-4S cable, which is typically used for data transfer or programming, into an interface cable for these specific HT models. The content focuses on the electrical connections required to achieve this cross-compatibility, presenting a practical solution for hams who already own a PG-4S and wish to avoid purchasing additional dedicated cables for their TH-F6A, TH-F7E, or TH-G71 radios. The adaptation process involves reconfiguring the connections to match the audio and data port requirements of the target handhelds. This technical information is particularly useful for operators seeking to interface their Kenwood HTs with sound cards for digital modes or for programming purposes, leveraging existing hardware. The page offers a direct, functional approach to hardware modification, emphasizing reusability and cost-effectiveness for Kenwood transceiver owners.
