I do this too. It's being taught in the courses I'm involved with. I had a unit go bad such that it was sending, but not able to switch to receive. Fortunately we caught it in a practice session and not in the field. It's important to check all transceivers in both functions. The whole party should receive you and not just the last guy.
Another "ritual" about making sure your beacon is on:
I was taught way back when that at some point before you start into hazardous terrain the party should check to make sure that everyone's beacon is transmitting. For me, that usually means that I ski to a safe spot about thirty yards away from the rest of the group and turn my transceiver to "receive". I then have each member of the party ski slowly by me while I watch (and listen) as my Tracker registers them and shows them coming. They then slow down so I can visually check that my transceiver shows them within a meter of me as they go by. They then ski 30 yards away from me and then next person skis toward me. At the end, I have the last person switch theirs to "receive" to make sure mine is transmitting.
I know we've "caught" several people over the years by doing that. That's even after asking if everybody's beacon is on.
Can someone who's taken a avy course recently tell me if that is still taught? I almost never see parties going out the gate at JH doing it.
