From PrimeTime Shortwave, it appears that they have DISCONTINUED broadcasting on the following frequencies (in English):
9830, 11785, 11690, 6100, 9450, 7540, 11665, 5850, 5950, 5985, 6085, 6875, 6985, 9505, 7520, 7730, 9385, 9550, 9625, 9505, 9680, 9715, 11530, 11580, 11740, 11830, 11835, 11865, 11910, 13615, 13690, 13695, 15255, 15770, 17555, 17725, 17750, 17795, 17845, 18930, 18980, 21525
Apparently, Shortwave Stuff hasn't deleated these frequencies yet.
Oddly, WYFR's website doesn't say anything about the reason these frequencies were dropped (In fact, they still show them on their schedule).
