The KFDshield™ is an open-source Key Fill Device compatible with the P25/TIA-102 AACD standard. In short, it is a shield that transforms your Arduino or other footprint-compatible microcontroller into a device capable of performing keyloading and other key maintenance operations on compliant Project 25 digital radios.

The KFDshield™ is an open-source Key Fill Device compatible with the P25/TIA-102 AACD standard. In short, it is a shield that transforms your Arduino or other footprint-compatible microcontroller into a device capable of performing keyloading and other key maintenance operations on compliant Project 25 digital radios.

The KFDtool software supports KFD features through the KFDtool hardware adapter (TWI/3WI/Three Wire Interface), as well as through a IP (UDP) connection (DLI/Data Link Independent interface). Keys and groups of keys can be saved to an AES-256 encrypted key container file, which can then be selected and loaded into a target device in one operation.

A fork of the amazing KFDTool software for an Arduino, plus schematics and board files for a shield. Completed shields can be purchased from the online store. Note: You must use the build of the KFDTool software attached to this GitHub repo in order for your homebrew adapter to work. The stock KFDTool software will not find your Arduino.

The KFDMicro (formerly known as MicroKFD) is a small, compact KFD keyfill device for P25 two-way radios. Schematics and board layout are available in this repo. The official boards (which provide a small kickback to the original developers) can be purchased at: https://store.omahacomms.com/product/kfdmicro/

2023年5月21日 · It's all about trying to figure how the OEM got to the 3WI. For example, Johnson (and now Kenwood) used a RS-232 to 3WI converter in their keyload cables and the "KMF" …

2022年10月13日 · I have a KFDshield, a hirose cable that came with it, and an NTN8613C keyload adapter. It detects the shield as an Arduino Uno on COM10 in Device Manager. The KFDtool software recognizes the shield, and the self test always passes. I have one XTS2500 that keyloads fine with no issues.
