    That's really cool! I don't know much about satellite amateur radio - but if it's always in one place, utterly reachable at any time, won't it likely be completely jammed up with all the US/Canada hams wanting to use what I'm sure will be just a handful of frequencies?

    Or am I not understanding how it will work...

    Either way, that's way cool news!

    Would've been nice to get the frequency of it!!!!!

    Two ways to access the satellite are planned:

    -Direct: 5Ghz Uplink, 10Ghz Downlink
    -Gateway: Ground based stations will have input/output on traditional ham bands/modes and handle interface with satellite.

    -Estimated launch late 2016 or 2017

    The Phase 4b team is working with commercial vendors to have TX/RX kits available for homebrewers. Target price about $1,000. Present Dish/DirectTV satellite dishes are suitable for use on both bands. Uplink will require about 1 Watt at 5 Ghz.

    -QRZed Satellite Forum

    -Phase 4B Team is looking for interested hams in Southern California, Texas and Maryland to help develop and test the ground terminals, direct Tx/Rx and software.

    As I should have expected (2m/70cm and probably even 1.2ghz is too crowded for a satellite that covers that much area)

    But lots of hams do not have equipment that operates on this band

    The plan is to have ground terminals/gateways that will allow hams to access the satellite with ordinary ham gear on the typical bands. Others who want to build/buy direct 5/10Ghz terminals can do so.

    The Phase 4B satellite will be capable of handling over 1,000 QSO (theoretical) simultaneously; voice and data.

    Amazing stuff! I really think I'm going to have to look into building a direct link system.... that would be cool! And I'd sure need to learn a lot of new stuff, which is always a good thing :)

    I must emphasize: Go watch the Palo Alto Radio Club, presentation at the QRZed link above. It explains quite well the Phase 4B program.

    All I want for Christmas it RS-10 back in the air, a great satellite.
    5 and 10 gHz , phooey. how about a linear transponder 1296 up 430 down. about 1 mHz wide.
