FWIW, in the 2010 ARRL publication titled "Remote Operating for Amateur Radio" Steve Ford states as follows on page 7-19:
In early 2010, Mikael Styrefors, SM2O, developed a device known as the RRC-1258MkII. This is a completely self contained "turnkey" solution for remote control of several types of ICOM, Kenwood, Yaesu and Elecraft transceivers. The RRC-1258MkII is actually sold as a package of two devices: one placed at the host transceiver and the other at the client location. They handle not only the command and control functions, but also the audio stream. Therefore, a computer at the host location is unnecessary unless you need it to control other items such as antenna rotators. The disadvantage, on the other hand, is that every client would need to have an RRC-1258. If you're putting together a remote station that is intended for a single client, this isn't an issue, but it would be problematic for multiple users. When this book went to press, the RRC-1258MkII package was selling for $450.00 and could be ordered online at
