During the summer June-July 2017, pilot Brian Lloyd commenced his round-the-world flight to commemorate Amelia Earhart’s route eighty years ago in 1937. The two month flight followed Earhart’s historic equatorial route. Royal Communications International, Inc. was honored to support Brian throughout his expedition.


“I chose the Micom3T transceiver for my historic recreation of Amelia Earhart's flight due to its robust construction and outstanding reputation for reliability in a harsh environment. While the control head is mounted in the cabin and lives in a more benign environment, the receiver/transmitter unit resides in an unheated and unpressurized avionics bay where the temperature may vary from +45C to -20C and the altitude may top 24,000 feet. In spite of this harsh environment the Micom3T performed well. 


But even the best equipment can fail and I did experience an intermittent failure of the receiver/transmitter unit. A single call to Royal Communications had a replacement unit on its way to me on the other side of the world in a day. Clearly the emphasis was to get my communications back up and running reliably as quickly as possible. I am extremely pleased with the level of support I received. The replacement unit operated and continues to operate reliably.


I recommend Royal Communications and Micom products without any reservation. They provide excellent service, great support, and reliable products. Thanks Royal!” - Brian Lloyd
