And also PSAT, with its 28.120 linear uplink and FM downlink. Although
someone has to be transmitting PSK31 for the auto-transponder to come up,
any weak CW in the same spectrum should be heard. Although I should not
recommend such use, so as not to disrupt normal band plan operations, it
is a nice experiment and since the PSK31 transponder is usually never more
than about 5% loaded (1 user maybe?) it's a shame not to experiment with

Watch your power on CW - especially on AO-7 [and PSAT]. A very strong CW
signal can make the transponder useless for others, and in the case of
AO-7, cause it to mode jump at certain times of the year.
