Dualwatch, Dual Spectrum Scope Control

The dualwatch operation and dual spectrum scopes with the waterfall functions* can be used on your remote PC. MAIN and SUB spectrum scopes can be observed on the RS-BA1 at the same time. Of course, the RS-BA1 can be used with Icom single receiver transceivers.

* The dualwatch and dual spectrum scope functions are only for the IC-7851, IC-7850 and IC-7610. The spectrum scope functions (single receive) are usable with the IC-7300, IC-9700, IC-705 and IC-905.

Most Functions Can Be Controlled

Most functions and modes of your transceiver, including interference rejection functions and IF filter settings, can be controlled using the CI-V commands. The following functions are added to the RS-BA1 Version 2.

  • Panel size can be enlarged (Normal or large size selectable)
  • Indicator click operation to change the settings
  • RIT and ⊿TX functions
  • [MUTE] button
  • SUB dial

Low Latency, High Quality Audio Over an IP Network

The RS-BA1 offers real-time operation with low latency, high quality audio. You can use the transceiver installed in another room using your home network, or even from a remote location over the Internet*.

* A static public IP address or Dynamic DNS is required for the base station (Server) PC, when you configure the remote control system through the Internet.
