I sweated a bit before sending those tests, but thought that it was
justified and useful as there had been more than one emergency beacon
received from one station in a little over one week and the user was
sure his D710 wasn't sending an emergency beacon.

It is certainly a possibility that the beacons are being corrupted after
transmission. There was a bogus position yesterday about the same time
that would have placed VE7HMW-9 about 330 km south of his actual
position. There's a lot of data to go through as it is transmitting at a
fairly rapid rate and with a (sigh) four hop path, leading to lots of dupes.
