Operating modes: PACTOR-4, PACTOR-3, PACTOR-2, PACTOR-1, WE-FAX (Receive), GPS/RTTY/NAVTEX decoder

Processor: Quadcore DSP from Freescale, 6400 MIPS, 64 Bit

Connections: USB (opt. Bluetooth), GPS (RS232 and TTL), radio AF / PTT (PTC-II compatible), radio-remote control (all usual transceiver types)

Audio Input level/imp: Max 3 V p-p, 47 KΩ

Audio Output level/imp: Max 4.5 V p-p, 1KΩ, both asymmetrically

Display: 8 dual-color LED’s (green, red) indicating all important operating states and signal tuning

Power supply: 10 – 25 V, typically 300 mA, max 400 mA at 10 V supply voltage

Weight / size: 450 g, 125 x 43 x 138 mm (width, height and depth)

 

PACTOR 4

Data throughput: Maximum 5512 bps without compression. Approx 10500 bps with PMC using text. This is reached with approx +16 dB @ 4 kHz in an AWGN channel. Under the usual channel conditions this is 1.5 – 3 times faster than PACTOR 3

Compatibility: Backward compatible to PACTOR-1/-2/-3. Automatic negotiation during link setup.

Noticeably improved performance with PACTOR 2 and PACTOR 3

ARQ protocol: Synchronized, similar to PACTOR 3, except 10 instead of 6 speed levels (“Waveforms”) and faster switching. Bandwidth is always smaller than 2400 Hz.

Channel equalization: Iterative adaptive equalizer for the coherent speed levels (5 – 10), RAKE receiver with maximum ratio combination for the splayed speed levels (2-4). Real-time multitasking operating system.

    LAST EVENT

    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
