GRITTY AFC is superb. I hate hate hate MMTTY AFC, if I leave it on all the
time it wanders off to infinity.

Tim,

That is user error. It only 'wanders off' as far as you have allowed.

Go to setup; AFC/ATC/PLL then set the 'sweep' number to something like 0.4. I believe the figure is directly related to the shift frequency, so setting it to 0.4 allows the AFC to 'wander' by 0.4 x 170Hz, or 68Hz.
