BFO issue when changing bandwidth #13

I'm using an ATS-25 running 3.4

I've noticed that if you use the BFO and adjust it to 250 (or anything other than zero) and you change the bandwidth it'll make the BFO change to zero even though the screen still shows the BFO is adjusted to 250. If you tune the BFO do 260 or 240 (using 10 stepping) after changing the bandwidth it'll correct the issue and it'll be the correct value seen on the screen, but if you adjust the bandwidth again it'll do the same thing.

I'm not sure if this is a limitation of the Sl4732 or it's an issue in the sketch.
