Page 36 FT DX 9000MP OPERATION MANUALANTConnect your main antenna(s) here, using a type-M (PL-259) plug and coaxial feedline for each. These antennaports are always used for transmission, and also are usedfor reception unless a separate receive antenna is alsoused for the main receiver. The internal antenna tuneraffects only the antenna(s) connected here, and onlyduring transmission. These connectors utilize Teflon®insulation for extreme durability and to ensure stableimpedance over the entire frequency range.RX OUTThese BNC jacks provide output of the receiver sig-nal lines from the Antenna jacks which are connectedto the Main (VFO-A) and sub (VFO-B) front ends.DC INConnect this socket to the OUTPUT socket on the FPS-9000H External Power Supply. This socket providesDC power supply voltage for the FT DX 9000MP.MICThis 8-pin jack accepts input from a microphone uti-lizing a traditional YAESU HF-transceiver pinout.REMOTEBy plugging in the supplied FH-2 Remote ControlKeypad to this gold-plated jack, direct access to theFTDX9000MP CPU is provided for control functionssuch as contest memory keying, plus frequency andfunction control. This jack may also be also used forremote control of the VL-1000 Linear Amplifier, ifused.+13.8VThis gold-plated output jack provides regulated, sepa-rately fused 13.8 VDC at up to 200 mA, to power anexternal device such as a packet TNC. Make sure yourdevice does not require more current (if it does, use aseparate power source).PTTThis gold-plated input jack may be used to providemanual transmitter activation using a footswitch orother switching device. Its function is identical to theMOX button (# ) on the front panel. The sameline is available at the PACKET and RTTY jacks forTNC control. Open-circuit voltage is +13.5 VDC, andclosed-circuit current is 5 mA.RX ANTThis type-M jack is for a separate receive-only an-tenna. An antenna connected here can be used, by boththe Main (VFO-A) and Sub (VFO-B) receivers, whenthe RX ANT button (# ) on the front panel ispressed.If you want to use some special kind of externalbandpass filter or preamplifier, you may connect itbetween the RX OUT and RX ANT jacks, as shownin the illustration.REAR P ANELANTENNA SWITCH(VFO-A)ANT “1”ANT “3”ANT “2”ANT “4”RX ANTRX OUT(MAIN)RX OUT(SUB)ANTENNA SWITCH(VFO-B)RX ANTENNA SWITCH(VFO-B)RX ANTENNA SWITCH(VFO-A)TX/RX RELAY Transmitter SectionMain (VFO-A) ReceiverSub (VFO-B) ReceiverBPF
