A timer question please: I assigned the timer to switch D on both of the above. Got the 660 recently for the slide levers etc. The 650 needs the two left rear switches repaired, levers snapped off. I discovered that I have to throw switch D twice: on off then again on to activate it. Same for both radios. Is this normal? I haven't flown the 660 yet and the 650 is 3 years old and works perfectly except for the two switches mentioned. I don't have them assigned to anything anyway.
Thanks for any advice.

Bill
