Controlling amateur radio transceivers remotely often requires dedicated software to interface with the radio's CAT (Computer Aided Transceiver) system. CATSPAW is a software utility specifically developed by N2OHZ for the Yaesu FT-100, facilitating computer-based control over various radio functions. The software provides an interface for adjusting parameters such as frequency, mode, and other operational settings, which can be particularly useful for remote station operation or automated tasks. While the specific features and user interface details are not extensively documented on the download page, the primary function centers on providing a digital control layer for the _FT-100_. This allows operators to integrate the transceiver into a larger station setup that might include logging programs or digital mode applications, enhancing the overall operational flexibility. The utility's design focuses on direct control, leveraging the radio's internal command set. As a downloadable executable, _CATSPAW_ represents a common approach to radio control software from its era, offering a direct link between a personal computer and a specific transceiver model.
