DB9 male to Phono/RCA high quality screened (shielded) cable. Length approx 1.5m/4ft 10ins.
This cable enables your Flex Radio 1500 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!
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 a DB9 male plug which connects to the Flexwire socket on the radio. This cable is wired to suit amplifiers that require a closure to ground to switch them to transmit.
Pin 1 of the DB9 connector is connected to the ground of the phono plug.
Pin 3 of the DB9 connector is connected to the centre pin of the phono plug.
Also perfect for switching the MFJ-1025 and MFJ-1026 noise cancellers and many transverters and Tx/Rx antenna switchers that require a low current/voltage DC closure to ground.
Please check carefully by consulting the manuals for both
your radio and your linear amplifier and ensure the keying output of
your radio and the switching input of your linear are compatible before
purchasing this cable. The radio or linear can be damaged by connecting
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.
