Installation and Interconnections FCC ID: K6620461X50 / IC: 511B-20461X50 Interfacing to Other Linear Amplifiers Note The TX GND OUT pin (pin 2) of the LINEAR jack is a transistor “open collector” circuit. It is capable of handling positive relay coil voltages up to +60VDC at 200 mA or +30 VDC at 1 A. If you plan to use multiple linear amplifiers for different bands, you must provide external band switching of the “Linear Tx” relay control line from the “TX GND OUT” line at the LINEAR jack. The specified range for ALC voltage to be used with the FT DX 3000 is 0 to -4 Volts DC. Amplifier systems utilizing different ALC voltages will not work correctly with the FT DX 3000, and their ALC lines must not be connected if this is the case. Note When the FC-40 is connected to the FTDX3000, TX GND (pin 2) of the TUNER jack and the LINEAR jack (pin 2) are common circuits. Therefore, the maximum voltage at TX GND (pin 2) of the LINEAR jack must not exceed +5V. Page 14 Important Note! Do not exceed the maximum voltage or current ratings for the “TX GND OUT” pin (pin 2) of the LINEAR jack. This line is not compatible with negative DC voltages, or AC voltages of any magnitude. Most amplifier control relay systems require only low DC voltage/current switching capability (typically, +12V DC at 25 ~ 75 mA), and the switching transistor in the FTDX3000 will easily accommodate such amplifiers.

Similarly, press and hold in this switch for one second to turn the transceiver off. [TUNE] Switch This is the on/off switch for the FTDX3000’s Automatic Antenna Tuner. Pressing this button momentarily places the antenna tuner in line between the transmitter final amplifier ” icon will apand the antenna jack (The “ pear in the display). Reception is not affected. Pressing and holding in this button for two seconds, while receiving in an amateur band, activates the transmitter for a few seconds while the automatic antenna tuner rematches the antenna system impedance for minimum SWR. The resulting setting is automatically stored in one of the antenna tuner’s 100 memories, for instant automatic recall later when the receiver is tuned near the same frequency. Pressing this button momentarily, while the Tuner is engaged, will take the Automatic Antenna tuner out of the transmit line. Page 16 Note: When the Automatic Antenna Tuner is tuning itself, a signal is being transmitted. Therefore, be certain that an antenna or dummy load is connected to the selected antenna jack before pressing and holding in the [TUNE] button to start antenna tuning. KEY Jack This 1/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or output from an external electronic keyer. Pinout is shown on page 15. Key up voltage is +3.3 V DC, and key down current is 0.3 mA. This jack may be configured for keyer, “Bug”, “straight key”, or computer keying interface operation via Menu item “018 KEYER F KEYER TYPE” (see page ???). There is another jack with the same name on the rear panel, and it may be configured independently for Internal Keyer or pseudo-straight-key operation. Note: You cannot use a 2-contact plug in this jack (to do so produces a constant “key down” condition). FT DX 3000 Operating Manual Front Panel Controls & Switches FCC ID: K6620461X50 / IC: 511B-20461X50 PHONES Jack A 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or 3-contact plugs. When a plug is inserted, the loudspeaker is disabled. Note: When wearing headphones, we recommend that you turn the AF Gain levels down to their lowest settings before turning power on, to minimize the impact on your hearing caused by audio “pops” during switchon. Microphone Connector This 8-pin jack accepts input from a microphone utilizing a traditional YAESU HF transceiver pinout. [ANT] Switch Pressing this switch selects the ANT 1, ANT 2 or the ANT 3 connector on the rear panel, and allows convenient antenna switching at the press of button. The selected antenna jack is indicated on the Block Diagram Display shown in the Transceiver Display. [IPO] (Intercept Point Optimization) Switch This button may be used to set the optimum front end characteristics of the receiver circuit for a very strong signal environment. Available selections are AMP 1 (low distortion amplifier), AMP 2 (2-stage low-distortion RF amplifier), or IPO (bypasses the front end RF amplifier), and the selected receiver RF amplifier appears in the IPO column of the Block Diagram Display on the display. [ATT] Switch This button selects the degree of attenuation, if any, to be applied to the receiver input. Available selections are –6 dB, –12 dB, –18 dB, or OFF. The attenuation level appears in the ATT column of the Block Diagram Display on the display. Advice: The Attenuator may be used in conjunction with the [IPO] button to provide two stages of signal reduction when an extremely strong signal is being received. [NB] Switch This button turns the IF Noise Blanker on and off. Press this button momentarily to reduce short-duration pulse noise. Available selections are ON, OFF, or NBW ON. The attenuation level appears in the ATT column of the Block Diagram Display on the display. [AGC] Switch This button selects the AGC characteristics for the receiver. Available selections are FAST, MID, SLOW, or AUTO. The “AGC” icon will change according to the AGC characteristics selected. Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. Press and hold in the [AGC] button for one second to disable the AGC (for testing or weak-signal reception). Advice: The Attenuator may be used in conjunction with the [IPO] button to provide two stages of signal reduction when an extremely strong signal is being received. If the AGC receiver-recovery time is set to “Off” by pressing and holding in the [AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded. [MOX] Switch Pressing this button engages the PTT (Push to Talk) circuit, to activate the transmitter (the LED inside this button will glow red). It must be turned off (the red LED will be off) for reception. This button replicates the action of the Push to Talk (PTT) switch on the microphone. When engaging the [MOX] button, or otherwise causing a transmission to be started, be certain you have either an antenna or 50-Ohm dummy load connected to the selected Antenna jack. [R.FLT] (Roofing Filter) Switch This button selects the bandwidth of the receiver first IF Roofing Filter. Available selections are 3 kHz, 6 kHz, 15 kHz, or Auto. The selected bandwidth appears in the R.FLT column of the Block Diagram Display on the display. Advice: Because the roofing filter is in the first IF, the protection it provides against interference is quite significant. When set to AUTO, SSB bandwidth is 6 kHz, CW is 3 kHz, FM and RTTY are 15 kHz. On a crowded SSB band, however, you may wish to select the 3 kHz filter, for the maximum possible interference rejection. FT DX 3000 Operating Manual Page 17 Front Panel Controls & Switches FCC ID: K6620461X50 / IC: 511B-20461X50 [MIC/SPEED] Knob MIC This knob adjusts the microphone input level for (non-processed) SSB and AM transmission. The display will show the relative microphone gain level for 3 seconds whenever this knob is turned. Advice: Adjust the [MIC GAIN] knob while speaking in a somewhat louder than normal voice level, watch the ALC level and adjust the [MIC GAIN] knob so that the ALC level indication just reaches the right edge of the ALC scale. Then, when you speak in your normal voice level, you will not be over-driving the microphone amplifier stages. SPEED This knob adjusts the keying speed of the internal CW keyer (4 ~ 60 WPM). Clockwise rotation increases the sending speed. The display will show the keying speed for 3 seconds whenever this knob is turned. Page 18 [PROC/CAR] Knob PRO This knob adjusts the compression (input) level of the transmitter RF speech processor in the SSB mode.

[CONT/APF] Knob [BK-IN] Switch CONT In the SSB, AM, and FM modes, press the [CONT/ APF] switch to turn the inner [CONT/APF] knob selects the desired CONTOUR filter response. The CONTOUR filter is engaged via the [CONT/APF] switch. APF In the CW mode, press the [CONT/APF] switch to turn the inner [CONT/APF] knob selects the desired APF (Audio Peak Filter) response. The APF is engaged via the [CONT/APF] switch. [CONT/APF] Switch Pressing this button allows you to select the DSP Contour filter response using the [ CONT/APF ] knob. While activated, the LED inside this button glows orange. Press the [CONT/APF] knob briefly to toggle the IF Contour filter on/off. Furthermore, in the CW mode, pressing this button to activate the APF (Audio Peak Filter) which provides a very narrow audio bandwidth. The APF circuit is an automatic circuit, and there is no adjustment knob for the APF. [SHIFT Knob] (Except on FM mode) Rotate the inner [SHIFT] to move the passband of the IF DSP filter by 20 Hz steps. The total adjustment range is ±1 kHz. The position of the passband can be observed on the display. Furthermore, the display will show the shift value of the IF SHIFT for 3 seconds whenever the [SHIFT] knob is turned. FT DX 3000 Operating Manual This button turns the CW break-in capability on and off. While CW break-in is activated, the LED inside this button glows orange. [AF] Knob AF Knob The inner [AF GAIN] knob sets the receiver’s audio volume level. Typically, you will operate with this control set between the 9 o’clock and 10 o’clock positions. [RF/SQL] Knob RF The outer [RF/SQL] knob is the receiver’s RF gain control, which adjusts the gain of the receiver’s RF and IF amplifier stages. This control is normally left in the fully clockwise position. SQL This knob sets the signal level threshold, below which the receiver audio is muted, in all modes. It is very useful during local rag-chews, to eliminate noise between incoming transmissions. This control is normally kept fully counter-clockwise (off), except when scanning and during FM operation. [MONI] (Monitor) Switch This button enables the transmit monitor in all modes. While activated, the LED inside this button glows orange. Advice: When using headphones, the Monitor function is very helpful while adjusting the Parametric Equalizer or other voice quality adjustments. The voice heard in the headphones represents the transmitted audio qualities. Page 19 Front Panel Controls & Switches FCC ID: K6620461X50 / IC: 511B-20461X50 [SCOPE] Switch T. B. D. [AUTO] Switch T.
