For the remaining avionic equipment repeat all interference checks
during a flight and include all equipment not checked out on ground
before.
A communication performance check in the low, mid and high frequency
band of the AR6201-(X0X) should be included. Verify the receiver output
produces a clear and understandable audio output. Verify the transmitter
by contacting another station and getting a report of reliable
communications. Ensure the range check to a far station does not take
place closer than appx.100 m from your own position.
