Slow start, but a good finale.
Kally Yao was very helpful, albeit a little slow in resolving my issues. I did receive the two replacement XM generators finally and, except for one glitch, at the beginning, they seem to be running fine now. The glitch in question was that when I tried to run the signal detect function on them, one of them showed a steady light, instead of a flashing light, at first. But, after re-scanning the generators and trying again, it gave the flashing light, so perhaps all is well, after all. Thank you Kally! Thank you Spooky!
