Re: Open Source Hardware...

The Winlink development team would be interested in purchasing two units when available through our 501C3 organization the Amateur Radio safety Foundation. We have a number sights were these could be tested here in Florida.
I have felt for a long time this is the kind of product that is needed in amateur radio. It provides an important vehicle to leverage and encourage advancement in digital communications.
I am also working with the CODEC2 group on the open source CODEC 2 and modem.  This radio should be very possible to support continual voice and relatively high bandwidth FEC data simultaneously.

... doesn't exist.

This forum has been wonderfully active on a variety of topics. It's great to see the exchange as hams weigh in with their hopes and dreams, but there is one topic that I need to address; the notion of open source hardware.

I worked in Silicon Valley for 30 years, both with and for, a variety of semiconductor companies. I have personally negotiated with both ARM and MIPs and let me tell you, there is no open source hardware.

Today's designs use high integration ICs which are designed in HDLs. They often include licensed IP from other sources under highly restrictive agreements. They are the companies most valuable assets and they are not released to anyone in any form.

In order for us to use these devices we may enter into Non Disclosure Agreements which state that we will not release any design information to third parties, that means you. In particular if there are errata we cannot share either the problem or the fix.

LEGAL DISCLAIMER: I am not saying that any vendors chips that I use now, or have ever used, actually have now or ever have had any errata (hi hi).

What we will provide is schematics and assembly diagrams of released product under copyright. In particular, we will document all connector interfaces both external and internal, to aid in experimentation.

We will not be posting manufacturing data, such as gerber files, detailed BOMs and mechanical drawings, but if you have an amateur radio project that requires more information; send us an email briefly describing what you'r trying to do and we'll do our best to help you.
