AJE is still on 97W I think. The launch of AJAM pushed them to scramble the signal -- probably at the behest of cable companies.
AJAM is in about 62 million US homes and that space on cable networks is worth something. It probably depends on what they plan to do with it. They could sell the channel to someone else, like Current TV sold to Al Jazeera for the launch of AJAM, or they could switch the feed to AJE. I suspect the former because they said today that they plan to expand digital output in the US, and they probably don't want to be dealing with cable companies and legacy media advertising sales. That being said, they might supplement AJE until their various contracts run out.
If it's gone from cable, you'd think it would come back FTA on 97W ... but I guess it all depends if the transmission department gets the memo. The customers who have access to AJE will all have decoders now and FTA is a small enough audience for it to not be high on their to-do list. But let's hope it does come back.
