Transponders For Rent???
Yes, I would rent in a minute. This would be my solution for working the sats. in the Wisconsin Winter! Brad Smith KC9UQR <So, like "FM Tower for Rent", signs as seen all over the U.S., could we soon see "GEO TV Satellite transponder for rent" as well ?Maybe this could be an answer to a ham GEO transponder ?>
Since the potential rentable birds generally all use DVB-S2 as a downlink, then the work Phase 4 Ground is doing to bring that entire standard to open source amateur radio use would seem to be quite relevant.
Different question is how to handle amateur uplinks, but there are some internet backhaul options there that would work very well as an intermediate step.
Great question and discussion.

Wouldn't the fact the uplink wasn't happening on amateur radio frequencies or perhaps indirectly then backhauled over the internet then uplinked on Commerical frequencies remove the "amateur radio component"? thus bring into question whether it's really open and within the ethos of the hobby? it would be like MMDVM which doesn't really appeal to me.

They are taking a publically available capture file of APRS traffic (available to anyone on FINDU.COM) and uplinking a copy of it to their satelilte non-profit file system.
With the creativity of some hams. I see potential for experimentation in finding ways to use this capability for Amateur radio disaster response in remote areas. We listen to broadcast NOAA weather reports and make use of that too.

This is interesting for sure, Michelle. Traditionally, amateur satellites (and symbiants) have been self-contained RX and TX systems.
Conjecture follows...If DVB-S2 could be negotiated to provide the downlink, the missing component is an uplink within the amateur bands (just restating you). That means (if it can be negotiated), our work is cut in half because we are reduced to providing the uplink (RX) side and a pathway to the DVB-S2 downlink. Of course, this is an oversimplification because we would also need all of the things that make a symbiant palatable to the host system. Interesting thought experiment, though. Ev

I got a call from a space industry contact who saw this post.
DVB-S2X down, FDMA up, single carrier, reasonable rent, public safety partner. Money for a year's worth could be raised in a single campaign.
I'll see what I can find out and draw up a proposal.

The concept of using the Internet for A/V uplink isn't really new. Skype has been used by hams to deliver computer mike audio to remote HF stations for years. The concept was described as the Internet becoming an "extension of the microphone cord." Just so, Skype (or your A/V app of choice) could be used to deliver video to to the sat service uplink station. The Internet becoming "an extension of the video camera cord." To take this idea a bit further, since there is no ham frequency RF involved for the uplink at least, the sender might not even have to be a licensed ham. Any school, college or club could immediately start building a ground station from scratch or from COTS parts. Even cheap Chinese satellite TV top boxes have been used for QO-100 DATV reception. This would certainly enlarge the client base for the use of such a GEO ham system. More money to pay the rent...

Different question is how to handle amateur uplinks, but there are some internet backhaul options there that would work very well as an intermediate step.
Great question and discussion.

To take this idea a bit further, since there is no ham frequency RF involved for the uplink at least, the sender might not even have to be a licensed ham.
I'm no lawyer, but this seems to be violating the spirit of amateur radio. You're proposing an Internet to RF gateway where anyone could connect and cause their "third party communications" (97.115) to be transmitted to the satellite and then relayed back down to an earth station?
I this case, who is the control operator (97.7)? I think that's where your plan breaks down, and why things like Echolink are only open to licensed amateurs.
Unfortunately, the removal of the "experience required" and Morse code testing has generated a large number of $25-Beofeng-never-made-a-contact Extras. If one can't be bothered to memorize the answers to a pitifully small test pool, one doesn't belong on amateur frequencies.

Ken,
Based on the specs you quoted above your email "can you use the ft-818 and arrow"
The simple and honest answer is no, it would require different equipment likely SDR based on microwave frequencies.
