Why Micom?

Wild Fires



In the last decade, the world has been inundated by natural disasters, and man-made incidents of a magnitude not seen in many decades, leading to a loss of hundreds of thousands of lives, destruction of millions of homes and buildings and the complete ruin of critical infrastructures. These tragic events increase the recognition that impaired or lost communications coupled with a lack of real time access to critical information, can dramatically reduce the ability to recover from such disasters. During such events, most of the conventional communications infrastructures such as telephone lines, cellular phones, satellites and other two- way radio communications are either saturated or not operational. Many levels of government and public safety  recognize that HF-SSB communication  are paramount for providing vital logistics and command and control support during major emergencies.

The Micom-3 transceiver system operates in the 1.6 to 30 MHz frequency range. The radio receives and transmits Voice, Data, and Telegraphy (CW) using upper sideband (USB), lower sideband (LSB), amplitude modulation equivalent (AME) and ISB (Independent Sideband for high speed data transmission).

The radio complies with all MIL-STD-810F and EMI requirements, and meets FCC, NTIA, and Industry Canada standards. It has been tested by DOD's Joint Interoperability Test Center (JITC) and certified for compliance with the ALE requirements in MIL-STD-188-141B.

The radio system can be controlled and operated from a remote location.  There are several remote control options, ranging from 2-wire direct connection for up to 3km, Fiber Optic for in building and secure locations, and IP connection for in building or around the world.

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
