Yes, we DO need/want a GEO sat with ham transponders over the Americas !

    More generally, Amateur Radio was the first global maker community, and in general freely shared designs. "Open Source", however, doesn't just mean publishing or sharing your designs. It also requires that you convey the right to use, modify, and redistribute them.

    AMSAT has been generally, freely sharing its designs for decades. As with anything in life, there are some exceptions. Offer not valid in all areas. Void where prohibited.

    The OHL is an OK choice for hardware, and Bdale knows about Open Source. Where's the code? It wasn't immediately obvious.

    Who suggested they were or should? My response was just to point out that neither the federal nor state governments give a damn about the constitution.

    States can't beat the 1st amendment, but they CAN beat the 2nd? You sound like you may be perfect for politics. ;)

    This is true.
    We have seen the parallels to the open source challenge lately in the development of HF/VHF computer sound card digital modes to be used on ham radio frequencies.
    Pactor 2,3 and 4 is completely closed source and proprietary.
    To the extent that the mode could be construed as "encrypted".
    I.e. There is no easy way for the government to eavesdrop on a locked ARQ conversation.
    It is now challenged by the FCC in Petition RM11831.

    Furthermore, I was heavily involved in the Beta testing of Winmor, which was supposed to be open source, but the final code was held close, by the architect.
    The same with ARDOP, and the latest very fast VARA HF and VARA FM, which is proven much faster and more robust than Packet AX.25
    Indeed, VARA FM could be a great digital mode for future FM satellites.

    It is understandable that retired software engineers would dabble in developing new systems to be Beta tested and used on ham radio frequencies as well, but holding the code close in order to monetize their effort eventually.
    Actually, this concept of using your ham radio compatriots as inexpensive R&D for your eventual proprietary software, is brilliant.
    But it is not in the true spirit of ham radio.

    So, yes, open source must be fully open source.
    Both hardware and software.
