RadioHead and Servo compile problems
You can force the RadioHead library to use Timer 2 instead. This can be done by enabling the define RH_ASK_ARDUINO_USE_TIMER2 near the top of RH_ASK.cpp.

More details about how to do this may be found in the RadioHead library documentation. Please see https://www.airspayce.com/mikem/arduino/RadioHead/classRH__ASK.html. 

Cheers!
