- The digital voice recorder captures both receive and transmit audio to your SD or USB storage devices. Up to 9 hours of continuous audio recording is possible with 2 GB of storage. Record your QSO with a rare entity or record your operating time in a contest. Operating frequency, mode, S-meter and output power are automatically captured.

Whether operating phone, CW, RTTY or
PSK31/63, the IC-7851 has a convenient
memory keyer to ease operations. Record your
CQ, station information or other items in one of
8 keyer memories for the CW and digital modes;
4 memories for phone operation. For CW, the
memory keyer has timesaving functions like auto
repeat, contest serial number counter and short
Morse number functions. For phone operation,
you have a voice-saving auto repeat function.
The automatic antenna tuner utilizes tunesetting memories to record the best tuner configuration for the lowest SWR. This allows a faster response time when jumping bands or moving around in the same band.
With six antenna ports – two receive-only and
four receive/transmit – the IC-7851 enables
the operator to have fingertip control over a
vast array of antenna configurations. Switch to
80/160m and you want to use your beverage
antenna for receive, but transmit on your
vertical. Not a problem: the antenna switch
memory will automatically switch antennas
when you select the band you want to operate.
This is very convenient when using the
RS-BA1 for remote base operation.
The IC-7851 has various computer interfaces,
giving you maximum connectivity between
your computer and radio. Digital modes
become a snap when controlling with the USB
port. USB audio and some CI-V commands
including USB send (DTR/RTS) and USB
keying (CW and RTTY) are selectable. You
can also interface your computer with the S/P
DIF optical digital interface provides audio I/O.
The Ethernet jack allows you to connect the
IC-7851 directly to your router and control your
radio over your wireless Internet, or travel the
globe and operate your station remotely over
the Internet.
The IC-7851 can grow as feature and function enhancements become available via the USB or your SD Card.
Remote base operation is made easy as the IC-7851 operating system incorporates
the remote base server software. A computer is not required in
the shack for audio or rig control. Up to three, unique user log-in/password
configurations are part of the internal server. As the rig control has a priority
of service, the controls will feel like you are right in front of your rig.
Optional RS-BA1 main features
● Most functions of your transceiver, including interference rejection
functions and IF filter settings, can be controlled. Also, received
signal strength and SWR can be observed on the computer display.
● Received voice recording function.
● Optional RC-28 USB remote encoder provides a hardware dial/transmit
functions for a realistic dial operation.
● The IC-7851 can wake-up from the standby mode through the RS-BA1 software.
