Servo.h and RadioHead library conflict

Projects General Guidance
1

I am using Feather32u4 from adafruit and Arduino IDE. The problem is that when I include radiohead #include <RH_RF95.h> and #include <Servo.h>, I get error message. After doing some research, it looks like they are both running on a same timer. Does anyone know how to fix this problem? I already tried using the ServoTimer2 library that uses timer2 but I believe that Feather32u4 does not have timer2 but rather timer3.

Arduino: 1.8.1 (Windows 10), Board: "Adafruit Feather 32u4"

libraries\RadioHead\RH_ASK.cpp.o (symbol from plugin): In function `RH_ASK::maxMessageLength()':

(.text+0x0): multiple definition of `__vector_17'

libraries\Servo\avr\Servo.cpp.o (symbol from plugin):(.text+0x0): first defined here

collect2.exe: error: ld returned 1 exit status

exit status 1

See: Arduino Uno not including two header files at the same time - Arduino Stack Exchange
You have to define
#define RH_ASK_ARDUINO_USE_TIMER2
in
RH_ASK.h
