I noted a number of times the past few days either AO-7 & XW-1 or VO-52 & XW-1 were visible to each other over NA. 5 KHz of VO-52s downlink and all of AO-7's 2m downlink fall into XW_1's uplink. With signals as strong as they are, it should be possible to make cross satellite contacts, ie. U/U. In on VO-52 or AO-7, out on XW-1. Just an observation but I don't recommend trying it as may interfere with other users.
