a1bill,
Listened to the broadcast and it's a good description of how they operate the Growler. However, from 1 hour on the comments about the F-35 are hopes. e.g. Reference updating the F18 mission tapes between sorties he adds that, "we hope to be able to do that with the F-35 as well".
I am not sure how you reach from that comment to, "The partners and even FMS customers can add to the Cyber/EM spectrum of their EW suite. I think it is a layered approach that has a preprogrammed suite that is added to from the battlespace. In real time or between missions."
In fact, the Sweetman article would seem to dash those hopes.
