5 and 243 MHz while simultaneously monitoring the mil std 1553b pdf channel selected. Transmitter power ranges from 5 to 23 watts, depending on frequency and mode.
The ARC-210 program began in 1990 and is installed on more than 180 platforms worldwide and is operating in more than 40 countries. October 2016, 40,000 had been delivered. 2 billion in sales for the company. There have been five generations of the radios.
Models include the RT-1556, RT-1794, RT-1824, RT-1851, RT-1851A, and RT-1939, RT-1939A, RT-1990, RT-1990A. The earliest model covered 30-400 MHz. The transceiver weights about 12.

MIL-STD-1553B, which superseded the earlier 1975 specification MIL-STD-1553A, was published in 1978. The basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required.
It was found that when the standard did not define an item, there was no coordination in its use. Hardware and software had to be redesigned for each new application. The primary goal of the 1553B was to provide flexibility without creating new designs for each new user. This was accomplished by specifying the electrical interfaces explicitly so that electrical compatibility between designs by different manufacturers could be assured. Six change notices to the standard have been published since 1978.
