• Dual receive with split transfer A feature
Although the TS-890S does not have a simultaneous dual-band reception feature, it can be combined with the
TS-590 series or another TS-890S transceiver to offer a powerful dual-receive feature. While the basic operation is
application of the split transfer function, the conventional split transfer feature is further expanded on the TS-890S to
enable smooth operation with simultaneous reception of two bands.
There are two split transfer modes, A and B, for the transceiver pair. Between them, the newly-added split transfer A
is closer to the simultaneous reception function available on models such as the TS-990S.
Transceivers that can be combined include the TS-890S series, TS-590G series and TS-590 series (only functions
as a sub-receiver). When combining the TS-890S with a TS-590G model, it is also possible to configure one of them
as the main transceiver.
The TS-590 series does not have a feature for branching the output received into two, and thus cannot be configured
as the main transceiver. Use an RS-232C cross cable to connect the COM ports of the two transceivers to enable
mutual transfer of data.
Firmware compatibility is necessary on the TS-590 transceiver in order to use this feature on a TS-590 or TS-590G
transceiver. (TS-590:Ver.2.04 or later/ TS-590G series:Ver.1.05 or later)
Both the TS-890S and TS-590 series comes with a 9-pin D-sub COM port. Connect them using an RS-232C cross
cable and configure the necessary items for split transfer A in the menu.
D-sub 9-pin RS-232C cross cables are sold as "interlink cables". Connect the antenna terminal of the TS-590 with
the ANT OUT terminal of the TS-890S using a coaxial cable, followed by setting the ANT OUT feature on the front
panel of the TS-890S to ON.
Doing so distributes the signal from the antenna to the TS-890S unit and the TS-590.
By configuring the sub-receiver settings for split transfer A on the TS-590, transmission is prohibited automatically
and therefore there is no need for manual setting to prevent inadvertent transmission by the TS-590.
Configure the TS-890S as follows.
• Menu [7-04] "Quick Data Transfer": Select A (TX/RX)
• Menu [7-00] "Baud Rate (COM Port)": Select 115200 [bps]
• Menu [3-12] "Split Frequency Offset by RIT/XIT Control": Select TX Frequency Offset while RX
Configure the TS-590 as follows.
• Menu [64]: Select A-SUB R
• Menu [67]: Select 115200 bps
Enable the split operation mode on the TS-890S and set VFO A/B. When TX VFO on the TS-890S is altered, the RX
frequency on the TS-590G will change automatically. To change the TX frequency on the TS-890S, set XIT to ON
and turn the RIT/XIT knob. Alternatively, the RX frequency of the TS-590 can be adjusted by pressing and holding
down the TF-SET button and turning the main dial at the same time. When the frequency on the TS-590G is altered,
this is transferred to the transmitting end of the TS-890S by pressing the Q-MIN button on the TS-590G.
