 +Yaesu FTM-300 requires higher logic levels than BN-220 can provide. MAX3232 is used to translate lower TTL logic levels to higher RS232 logic levels - [[https://www.sparkfun.com/tutorials/215|Quick tutorial here.]] GPS module will require to be set to GPS constellation only in u-center. Radio needs to be set to external GPS device. Transmit from the radio Data Tx to GPS receive Data Rx does not need to be connected. Baud rate is set to 9600.
