a) I think that the radio license which you must get as part of your PPL course covers the operation of whatever radio you have IN THE AIRCRAFT, so a license is required only if you are to use the transceiver outside it
That bit is correct
but !!!!
The radio set itself needs to be licenced as do the radios installed in the aircraft.
