Operating the microsats was a completely hands-free procedure. You told your groundstation what sort of files you were interested in, and went out to lunch. While you were away, the bird came up over the hill, rotors rotated, frequencies dopplered, and by the time you got back, the pass was over, your outgoing files were gone, your inbox was full of interesting stuff, and your gear was idle. Once you were all set up, it was brilliant. No 'operating' in the conventional sense, but absolutely effortless transfer of files and messages.
But transfer rates were relatively low, passes were short, and it could take several passes for in/outbound files to complete.
And the birds had huge data capacities, like 4 megabytes total. Yes, meg. So you had to keep your files small. But they could be anything you like, text or binary. Images, software, etc.
I met and became friends with a guy in England via the microsats, and when he was coming to 8P he sent me a JPEG so I would recognize him at the airport.
There were other types of BBS flying, too. The Fuji birds were pretty much exactly like terrestrial packet boards. Once you got ***CONNECTED you could ask for a menu and issue commands in the normal way.

Hey All,
I want to throw out a question about the Bulletin Board Systems thathave flown on several amateur radio satellites in the past. A majority of these flew prior to my involvement in ham radio (licensed in 2004) and for many years I haven't had a great setup for satellite work, largely due to funds as a high school student back in the day and nowadays since I move around quite often from home to college. I would like this conversation to stay on-topic since I realize this could stray pretty easily!
What was it like to have an orbiting BBS? What types offiles/information were sent and how convenient was it? Was it just text or could people send small images? I may not be aware of a currently working BBS, the last one I know of off-hand was on AO-51 if I am not mistaken. I am simply fascinated with the ability to send and receive data to and from an orbiting satellite in this fashion. I look forward to hearing any responses.
