I haven't tuned in today, but the last few times I have (the latest being two evenings ago, 01 OCT c. 0200 UTC) it's been on at 5910.340 kHz, significantly off 5910 which probably accounts for the wavering you're hearing. I'm not sure if that's a purposeful change in frequency or not, since it was pretty much dead on 5910 earlier in the year, but it's been steady since I first noticed it in September.
