HF transceivers have an accessory connector that provides TX and RX audio, Push-to-Talk input, programming and a variety of other inputs/outputs.  The accessories that are available will enhance the transceivers capabilities.  Voice privacy, phone patch, modems, cross-band... the possibilities are many. 


Simulcast on 2, 3, or 4 radios

The Micom™ Link II is a new generation of multi-crosspatch with capabilities for different users of VHF or UHF. The crosspatch is capable of analog and/or digital radios with HF/ SSB.


The Micom™ Link II allows a user to transmit on a single radio as well as simulcast on 2, 3, or 4 radios, while in repeater (RPT) mode. The operator can deselect the appropriate radio to transmit exclusively on a selected radio.


Micom™ Link II may also be configured for VOX or COR operation for each individual radio. The VOX circuit has a two second hang time to prevent premature dropping of the PTT when the audio drops .


On VHF/UHF networks with the Micom™ Link II we can activate (ON) and Deactivate (OFF) the crosspatch by a specific DTMF sequence sent by a station on the VHF/UHF network without the need of an operator.


When the networks are linked, incoming audio from the HF network is broadcast on the VHF/UHF network and vice versa.


Mobile antenna mount solution

Affordable, Reliable and Removable Royal Communications International introduces the first hassle-free, removable antenna mount.

Universal mounting system for canister style antenna tuners like the MICOM WIMA antenna or similar.

Mounts in a standard 2” receiver style hitch.

Allows full access to the rear hatch or tailgate in the open position.

Powder-coated box steel design for maximum strength and durability.

Includes grounding strap.


24VDC power supply

The Barrett 4022 Power Supply with built-in charger is designed to provide regulated power to one 4050 Transceiver and one accessory. The 4022 also has provision for a battery backup system in case of mains power failure. The battery backup incorporates a true automatic no-break change over circuit with a battery charging system, which restricts the output to the maximum 13.8 V of the battery.


13.8VDC output with battery backup

The LPHP-4012-BC is a desktop power supply that comes with adjustable DC output voltage and a power connection factor of .98, which saves 25% of electrical cost. It comes with a short circuit/over load/ over temperature protection and a cooling fan that helps flow air throughout the unit. Battery backup/charge circuit is also included.


Automatic HF/ALE phone patch (FLN2824)

The Micom-Tel FLN2824, automatic telephone interconnect via PABX/PSTN for use in ALE mode will enhances long distance communications via HF link or land line to any remote HF site. It offers the capability to connect the Micom-Radio to telephone PABX networks. Using a Micom-Radio, any remote HF station (fixed and/or mobile) can be easily interconnected to a land line or mobile/cellular telephone.

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
