I've noticed a lot of people tweeting that they weren't able to hear BY70-1 on recent passes.

Most of the issue probably lies with the fact that the low orbit of the sat is causing wide variations in pass times. The TLEs in the Amsat kep file aren't updated often enough to keep up with these variations, so you might try the keps from Celestrak

These are updated several times a day, and should provide better tracking than the Amsat keps.
