[amsat-bb] How busy are the linear transponder satellites?

Usually plenty of room and often there are several
actual ragchews and a couple Rover-Grid operations.
Not at all like the chaos and rudeness of the FM

I know that the FM satellites, primarily SO-50 and AO-85, can be quite

congested during a pass.  This is understandable, since each satellite

presents only one channel.  On the other hand, the linear transponder

satellites can support multiple communication channels, due to the

available bandwidth.  This ranges from 20 KHz (XW-2A/B/C/D/F) to 100 KHz

(FO-29, AO-7).  From your experience running SSB, how congested or how

utilized, is the bandwidth of these satellites?  Is there usually plenty

of room to spare, or is it a challenge to find a place within the

available bandwidth to conduct a QSO?

Thanks and 73,
