Most other transceivers’ keying common is tied to the transceiver chassis. The exception is that
most Kenwood transceiver keying relays have a floating common. To facilitate connections to
Kenwood 7-pin DIN Remote connectors, a new keying line cable is available from DX
Engineering, the DXE-KWD-RTR. This special cable assembly adds the shield to the chassis
ground connection on the 7-pin DIN shell to allow proper operation of a Kenwood transceiver with
the RTR-2.
With this special cable wiring for Kenwood transceivers, Ground On Transmit and RX ENABLE
are functional for the RTR-2, NCC-2 and RTR-1 units.
Note: The DXE-KWD-RTR cable does not provide an ALC line due to its lack of use.
The following Kenwood radios are known to have the 7-pin DIN REMOTE connector for amplifier
keying line connection and can use the DXE-KWD-RTR cable:
TS-120, TS-130, TS-140S,TS-2000, TS-2000X, TS-B2000,TS-430S, TS-440S, TS-450S, TS-50S,
TS-530S, TS-570D, TS-570DG,TS-570S, TS-570SG, TS-590S, TS-590SG, TS-680S, TS-690,
TS-690S,TS-850S, TS-870S, TS-930S (Some early unmodified TS-930 models are not supported),
TS-950S, TS-950SDX, TS-990S
