Beats me.   I have heard that many times (and not just recently).  A few minutes ago I was
calling CQ intermittantly, and just before I made a call, LEILA lit off and ran for 21 seconds
(according to my clock), and there had been nothing there before she started.
As to long runs of LIELA, I have seen that too.  I don't have a problem with LEILA jumping on
me, and I stop transmitting right away, but frequently notice that LEILA will continue for as
much as 45 seconds.  I have also verified that it's really LEILA by verifying the notch.
