A family of open source USB devices for amateur radio stations, all using this one VID/PID and identifying themselves to the host with a self-describing `GET_INFO` request (a protocol version and a device sub-ID, so one PID covers several device types without further allocations).

The first implementation is the "station I/O" device, based on the Cypress EZ-USB FX2LP (CY7C68013A) with our own 8051 firmware, loaded into RAM over USB: general-purpose I/O with a function map, a hardware transmit time-out and heartbeat for PTT lines, and PTT lead and lag sequencing. Later device types (for example a USB audio and CAT rig interface) will use the same protocol and the same PID, distinguished by the sub-ID and protocol version.

This is firmware for a popular commercial CYC68013A development board.
We currently see it at https://www.amazon.com/dp/B0855FJDBX for $10
A schematic is at

It is not currently necessary for anyone to manufacture the board, since
it is so inexpensive ready-made.

Hardware, firmware and host software for every device under this PID will remain under an OSI-approved open source licence (software) and a recognised open source hardware licence (hardware design files). The protocol and the device-type registry are in the repository.

Hams.com is an amateur radio service by Bruce Perens (K6BP), creator of the
Open Source Definition, which became the core of the Open Source Hardware
Definition.

Hams.com's open source projects include radio-control software, bench
instrument software, and open hardware and firmware for amateur radio
stations (https://github.com/BrucePerens/hams_open).
