Hmm... but how good is the signal with the C-1501 cards?
As I replaced my C-1500 with the C-2300 several years ago because the
signal on the C-1500 is really bad.
I'm just tired of messing with this now, so want to buy a new card
that will just work.
And now I'm not sure if I should get C-1501 or the Mystique/KNC one.
I guess the CI for the C-1500 work with the C-1501?
In that case it wouldn't cost much to buy a C-1501 to try, and if that
doesn't work get a Mystique/KNC with new CI if I get a bad signal with
the C-1501.
