The FTDX5000 is a leading-edge transceiver with a number of new and exciting features, some of which may be unfamiliar to you. [. . . ] In the "Off" mode, the transceiver will be directly connected to the coaxial cable connected to your antenna, and it will operate based on whatever impedance is present at the station end of the coax. [TUNE] Button [RF PWR] Knob ADVICE: The ATU circuit is located between the final amplifier and the rear-panel antenna jack; reception is not affected by the ATU. QUICK POINT: As shipped from the factory, only one ATU alignment point is saved on each Amateur band. This was memorized during the final alignment and performance verification stages on the production line. The momentary flickering of the " " icon occurs whenever you cross over into a new 10 kHz ATU memory window. NOTE: Please check the operating frequency before beginning the tuning process, to be sure you are not interfering with others who may already be using the frequency. TERMINOLOGY: Antenna Tuner Memories: The microprocessor of the ATU makes a note of the positions of the tuning capacitors and the selected inductors, and stores the data for each 10 kHz window in which tuning has occurred. This eliminates the need to re-tune every time you return to a frequency on which you already have completed the tuning process. Page 72 FTDX5000 OPERATING MANUAL USING THE AUTOMATIC ANTENNA TUNER ABOUT ATU OPERATION Figure 1 depicts a situation where normal tuning of the ATU has been successfully completed, and the tuning data has been stored in the ATU memory. In Figure 2, the operator has changed frequency, and the " " icon is shown. The operator presses and holds in the [TUNE] button for two seconds to begin impedance matching using the ATU. If a high SWR condition exists (above 3:1), corrective action must be taken in the antenna system to bring the impedance closer to 50 Ohms. The ATU will refuse to memorize settings on frequencies where the SWR exceeds 3:1. The high SWR may indicate a mechanical failure in the antenna or feed system, and such failures can lead to the generation of spurious signals causing TVI, etc. SWR: 2. 0 Feed Point SWR SWR: 1. 5 SWR: 1. 0 Frequency SWR after ATU Tuning FIGURE 1 The " " icon appears on the display when you transmit on this frequency Memorized ATU Tuning SWR: 3. 0 SWR: 3. 0 SWR: 2. 0 SWR: 1. 0 Frequency Retuned Setting FIGURE 2 About ATU Memories SWR (Post-tuning) Less than 1. 5:1 The tuning settings are committed to the ATU memory. SWR (Post-tuning) Greater than 1. 5:1 Tuning data will not be retained in memory. If you return to the same frequency, the tuning process must be repeated. SWR (Post-tuning) Greater than 3:1 The " " icon will light up, and tuning settings, if achieved, will not be memorized. Please investigate and resolve the high SWR condition before attempting further operation using this antenna. FTDX5000 OPERATING MANUAL Page 73 ENHANCING TRANSMIT SIGNAL QUALITY PARAMETRIC MICROPHONE EQUALIZER (SSB/AM/FM MODES) The FTDX5000 includes a unique Three-Band Parametric Microphone Equalizer, that provides precise, independent control over the low-, mid-, and treble-ranges in your voice waveform. You may utilize one group of settings when the speech processor is off, and an another independent group of settings when the speech processor is on. Setup of the Parametric Microphone Equalizer 1. Set the [RF PWR] knob to its minimum value, to reduce interference to other users during adjustment. ADVICE: We recommend you consider connecting a dummy load to one of the Antenna jacks, and monitor your signal on a separate receiver, to prevent interference to other users. You will have the best chance of hearing the effects of adjustments if you wear headphones (connected to the monitor receiver) while monitoring your transmitted signal. To adjust the Parametric Microphone Equalizer while the speech processor is disabled, press the [PROC] button until the " " icon appears (or blinks) in the display. To adjust the Parametric Microphone Equalizer with the speech processor engaged, press the [PROC] button until the " " and " " icon appears in the display.
