High quality screened (shielded) cable. Length approx 1.5m/4ft 10ins.

This cable enables your Yaesu radio to control the transmit/receive switching of your linear amplifier. Essential if your linear doesn't have RF sensed switching. Even with amplifiers with RF switching, it eliminates the need for switching delays that often mean missing the first part of the other station's transmission - irritating at best, but disastrous while contesting or working fast CW!

A state-of-the-art opto-isolated solid state relay is incorporated in the DIN connector which gives complete electrical isolation between the radio and amplifier, while providing up to 500mA switching capability at 48V DC or AC with only 10mA drawn from the radio.

One end of the cable has a Phono/RCA plug which connects to the Key, Tx or PTT input connector of the linear amplifier. The other end of the cable has an 8-pin mini-DIN plug which connects to the radio according to the following list:

FT-450 TUNER connector
FT-950 TUNER connector

FT-847 TUNER connector

FT-817 ACC connector
FT-857 CAT/Linear connector
FT-897 CAT/Linear connector

FT-840 BAND DATA connector

FT-991 TUN/LIN connector

The FT-847 TUNER connector keying output used by this cable is only active on HF. For other bands, the FT-847 also has 5 pin mini-DIN SBY connector with individual linear keying outputs available for HF, 50MHz, 144MHz and 430MHz. We sell a quad-band pigtail cable for the FT-847 SBY output, please visit our eBay shop.

The FT-450 and FT-950 also have a 10 pin LINEAR connector and we now have suitable cables. Please visit our eBay shop.

Also perfect for switching the MFJ-1025 and MFJ-1026 noise cancellers.

Although we are happy to offer advice, it is ultimately your responsibility to verify that the switching output of your transceiver and the switching input of your amplifier can be safely connected to each other using this cable.

The radio, cable or linear can be damaged by connecting incorrectly. Please check carefully by consulting the manual for your linear amplifier and make sure that you will not exceed the absolute maximum ratings of the relay:

• Switching voltage 60V DC/AC
• Continuous load current 500mA
• Isolation 2.5kV for 1 min
  

We also sell a version of this cable without the relay for amplifiers with low-current/low-voltage switching. Please visit our eBay shop.
