The difference between the daylight areas in the Southern and Northern Hemispheres is displayed correctly, and is updated in real time.
Advice: The order of the display of the cities can be changed later; for now, please just select one of the supplied city names. The entire screen will become the spectrum display, and you can see both strong and weak signals clearly and easily. The noise level on the band will vary according to conditions, your an- tenna, the time of day, etc. Press the [ F4 ] P. SRCH key to move the marker to the highest peak signal frequency.
With each press the [ F4 ] P. SRCH key, the Marker will shift to the strongest signal frequency away from the current frequency. As the sweep segment becomes narrower, the speed becomes faster, and the accuracy and resolution become enhanced. The starting point, located at the left edge of the screen, can be set via the Menu. Even if the screen span bandwidth is changed, the start frequency will not be changed.
By watching the screen, you can move your operation to frequencies where interesting activity appears on the display. With the Audio scope, the horizontal line represents frequency, and you can use this function check the fre- quency response within the TX bandwidth.
In the Oscilloscope mode, the horizontal line represents time, and you can check the RX signal waveform within the RX bandwidth, as well as the TX wave form. On receive, you can observe the signal characteristics and quality of the incoming signal, as well.
Date, time, frequency, and mode will be automatically stored, and you can save log data to the Compact Flash card for archive purposes. For use in a contest or otherwise, the settings for each operator may be stored for later recall when that operator signs on. When a log entry of interest is found, you may edit the information on that line, if you like. The measurement range is V, and the proper voltage is around 50 V. FTE Operating manual German.

These filters provide protection for the 2nd mixer, DSP, and other circuitry that follow and can dramatically improve reception on a very crowded band during a contest, etc.
Page Cont Contour Control Operation CONT C The Contour filtering system provides a gentle perturbation of the IF filter passband, so as to suppress or enhance certain frequency components modestly, so as to enhance the natural-sounding received signal. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency when eliminating the interference.
Moreover, the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity when interference on the band is low. By rotating the DNR knob, any of sixteen different noise- reduction algorithms can be selected; Because this is an Auto-Notch feature, there is no adjustment knob associated with this filter.
Advice If a very strong interfering carrier is encountered, we recommend you first use the IF Notch filter, as it is the most effective notching tool in the receiver section.
The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved. The Mute feature makes this simple to accom- plish. Because the improper enabling of this voltage could cause damage to other microphone types, the simple process for enabling the voltage has been made somewhat complicated, so as to prevent the voltage from being enabled by accident.
We recommend that the ATU be used whenever you operate on the D. The antenna system as seen by the transmitter is shown. After two or more years of heavy use, you may notice that the tuner memories are not being maintained, and that you have to re-tune when returning to a frequency on which you had previously stored tuning data.
Page 87 Slide the front panel diagonally upward and outward. The result is improved intelligibility when conditions are difficult. This bandwidth provides reasonable fidelity along with good talk power, and is typical of the bandwidth used for decades during SSB transmission.
However, the bandwidth may be varied by the operator, so as to provide different levels of fidelity or talk power, according to your preferences. Because the three ranges may be adjusted so precisely , it is possible to craft a response that provides a more natural and pleasant sound than you have ever experienced before.
Power output during Class-A operation is 75 Watts. The Voice Memory system includes five memories capable of storing up to 20 seconds of voice audio each. The maximum that any memory can hold is 20 seconds.
Page 95 D O Page Press the CLAR switch. This makes the FT D especially useful for high-level DX-pedition use, as the Split operation capability is very advanced and easy to use. Page Full Duplex Operation The FT D includes a unique capability among HF Important Guidelines for Full Duplex Operation transceivers: the ability to operate in a full duplex envi- Remember that, at your station location, the capability ronment, where by you can transmit on the Main band exists for damaging RF voltage to be conducted from your VFO-A while simultaneously tuning around, on a differ- transmitting antenna into your receiving antenna during Page D O Page The default weighting is a dash is three times longer than a dot or space.
Page Using Cw Reverse CW C CW R If you experience a difficult interference situation, where CW switch an interfering station cannot readily be eliminated, you may wish to try receiving using the opposite sideband. The default setting of 4 ms. Press the CW mode switch to engage CW 1. Be sure that Break-in is still turned Off. This technique is somewhat slower than when you send the message directly from your keyer paddle, but accuracy of character spacing is ensured.
Press the FM mode key to select the FM op- erating mode. H Be sure that the FM mode is being selected on the proper VFO; check the status of the A and B switches above the mode selection keys before making your mode selection. Rotate the Main Tuning Dial knob to the output frequency downlink from the repeater. By default, the 99 regular memories are contained in one group; These can quickly store operating parameters for later recall.
QMB C 1. Page Memory Groups 1. Press the MNU key to enter the Menu mode. MNU key 2. Page Memory Operation The memory system of the FT D allows storage and recall of up to 99 memories, each storing frequency, mode, and a wide variety of status information detailed previously.
The imbedded LED will glow Red, indicating that you are now ready to view memory channel con- tents. The memory channel number will appear in the multi-panel window.
