I do not believe this has been changed, it seems this discussion has occurred
many times on the sig before...

I never claimed otherwise. If I give a tracker to an expedition, it is my
responsibility to ensure its correct operation. That means I must be sure the
hard is in good condition, and that it is programmed correctly. 

We all place faith in the correct operation of our radios...if the dial says
144.39, we assume that is where it is transmitting...if there is a failure, and
it is transmitting on a local police frequency, we are responsible. Same is true
for any automatically controlled station.

This is where you are not following my argument. Control has NOT been delegated
to someone else, if it is my tracker I am still the control operator.

Again, I never claimed that. If it is my tracker, operating with my call, I am
completely responsible. All I claimed is that the operation is legal, but still,
like every other time I transmit, I am responsible for that transmission.

I don't want to be in the position to have to give the FCC any response...I do
my best to ensure that by operating within the rules and making sure my hardware
is functioning properly. The scenario you propose requires first some sort of
technical failure in the tracker that causes interference, second for the FCC to
notice and for the EIC to notify me, and third for the inability of anyone to
reach the transmitter. Three very rare events, but sure, it could happen.

And no, I wouldn't want to have to give the FCC that excuse, but if it were what
really happened, I would. I'd accept responsibility for it, and let the FCC do
what they will...

FCC rules require that satellite stations be under remote command as well, you
must be able to turn them off. However AO-10 has been uncommandable for over a
decade and continues to transmit. No one lost their license over that
one...clearly regulatory bodies understand hardware failures occur, and give
leeway in such cases. 

I maintain that not only is this sort of operation legal under part 97, but also
completely within the spirit of amateur radio. You feel differrently, that is
your right. Those that feel as I do will place trackers outside their physical
control, those that feel as you do won't. No big deal...
