9、k you for choosing the Elecraft K3S transceiver. The K3S is the same size and weight (9 lbs.) as its predecessor, the K3. Yet nearly all internal modules have been redesigned, providing enhanced performance and many new features. These include: Ultra low-noise synthesizer for exceptional receiver dy

10、namic range and transmit signal purity USB port for convenient, single-cable computer control and digital audio interface (an RS232 port is provided, as well, for station compatibility and P3 interfacing); pg. 18 Built-in second preamp for weak-signal work on 12, 10, and 6 meters; pg. 25 Three atten

11、uator settings (5/10/15 dB) to optimize performance in strong-signal conditions; pg. 25 Improved audio circuitry for clean, low-distortion stereo speaker output; pg. 80 Low-loss ATU option with a true bypass relay, maximizing efficiency with every antenna Accurate high-speed CW transmit timing, even

12、 when using SPLIT, RIT, and XIT 100-550 kHz coverage, including low-level 630-meter (472 kHz) transmit; pg. 41 Exterior changes include all-stainless-steel hardware, new display bezel, and a soft-touch VFO tuning knob. With its unique combination of compact size and world-class performance, your new

13、 K3S can handle the most demanding operating situations, whether youre at home or halfway around the world. 73, Wayne, N6KR Eric, WA6HHQ Key to Symbols and Text Styles Important read carefully Operating tip LSB .

15、cal MAIN menu entry CONFIG:KAT3 Typical CONFIG menu entry 4 Quick-Start Guide To get started using your K3S right away, please read this page and the two that follow, trying each of the controls. The text uses braces to refer to numbered elements in the front- and rear-panel illustrations below. For

16、 example, 1 in the text refers to . Later sections provide greater detail on all aspects of K3S operation. The first thing you need to know about the K3S is that most switches have two functions. Tap (press briefly) to activate the function labeled on a switch. Hold for about to 1 second to activate

17、 the function labeled below the switch. In the text, tap functions are shown like this example: MENU . An example of a hold function is CONFIG . Additional typographical conventions are shown on the previous page. Try tapping MENU 8. This brings up the MAIN menu. Rotating VFO B 19 selects menu entri

18、es, while rotating VFO A 22 changes their parameters. Tap MENU again to exit the menu. 1 5 Connections Connect a power supply to the DC input jack 26 (see Specifications, pg. 8). On the K3S /100, a circuit breaker is provided on the fan panel for the 100-W stage 39. You can power an accessory device

19、 from the switched DC output jack 40 (1.0 A max). Connect antenna to ANT1 29 and ground 38. With an ATU (pg. 24), you can also use ANT2 28. AUX RF 27 is for the sub RX; see pg. 17. ANT3 30 is used with the internal 2-m module (K144XV). Connect an RX-only antenna to RX ANT IN 35. The Basics Press POW

20、ER 5 to turn on the K3S. If there are any error indications, refer to pg. 74. TAP and HOLD Functions: Tapping briefly activates the function labeled on a switch. Holding for about 1/2 second activates the function labeled below a switch. Tap either end of BAND 7 to select a band, and MODE 6 for the

21、mode. Set AF gain using AF 2. Set RF to max. Plug phones in at 3. For SUB controls, see pg. 39. The large knob 22 controls VFO A (upper display, 10). The medium knob 19 controls VFO B (lower display, 11). VFO A is main RX/TX except in SPLIT (pg. 38). CMP / PWR is one of four multifunction controls 2

22、4. Each has two primary functions, indicated by green LEDs. The knob has a built-in switch; tap it to select either CMP (compression level) or PWR (power output). Hold the knob in to access its secondary function, MONitor level. Tap again to restore the primary function. Filter Controls Rotate the S

23、HIFT / LO CUT and HI CUT / WIDTH controls 23 to adjust the filter passband. Crystal filters FL1-FL5 are automatically selected as you change the band- width. Tap either knob to select shift/width or hi cut/lo cut. (See filter info, pg. 85.) Hold SHIFT / LO CUT to NORMalize the bandwidth (e.g., 400 H

24、z CW, 2.8 kHz SSB). Hold HI CUT / WIDTH to alternate between two filter setups, I and II (per-mode). Tap XFIL 13 to select crystal filters manually; this also removes any passband shift. Voice Modes 1 Hold METER 8 to see CMP / ALC levels. While talking, set MIC 25 for 4-7 bars of ALC, and CMP for th

25、e desired compression. Then return to SWR / PWR (pg. 30). Optional: Hold TEST 6 for TX TEST mode; allows off-air TX adjustments (pg. 13). Hold CMP / PWR 24 to set speech MONitor level; tap to return to CMP / PWR. Hold VOX 7 to select PTT or VOX. Hold SPEED / MIC to set VOX DELAY. Details: VOX, pg. 3

26、1; TX EQ, pg. 37; MIC SEL, pg. 55; SSB/AM/FM, pg. 30. CW Mode 37 SPEED 25 sets the CW keyer speed. Hold this knob to set semi-break-in DELAY. Hold QSK 7 to select full QSK (pg. 32.). Hold VOX 7 to select hit-the-key CW. Hold PITCH 18 to set sidetone pitch. Hold CMP / PWR to set sidetone MON level. T

27、ap CWT 18 for tuning aid 9 (pg. 36). With CWT on, SPOT auto-spots (pg. 32). To select CW text decode/display mode, hold TEXT DEC 18; rotate VFO B (pg. 32). CW keying is converted to DATA in FSK D and PSK D modes (below and pg. 36). Hold APF 13 to turn on audio peaking (APF) or dual-passband filterin

28、g (pg. 32). Data Modes 33 Tap MODE 6 until you see the DATA icon turn on (see Data Modes, pg. 33). Hold DATA MD 18. Use VFO B to select from: DATA A (PSK31, JT65, and other soundcard-based modes), AFSK A (soundcard-based RTTY), FSK D (RTTY via data input or keyer), or PSK D (PSK via data input or ke

29、yer). VFO A selects data baud rate for internal encoder/decoder, if applicable. APF turns on an RTTY filter (DTF, pg. 34). Hold PITCH 18 to select mark tone and shift (for encoder/decoder and RTTY filter). Hold TEXT DEC 18 to set up text decode. CWT shows tuning aid (pg. 36). 6 VFOs and RIT/XIT RATE

30、 21 selects 10 or 50 Hz VFO/RIT tuning. See VFO menu entries, pg. 57. FINE 21 selects 1-Hz steps. COARSE selects large steps (MAIN menu, VFO CRS). Tap FREQ ENT 21 to enter frequency in MHz using numeric keypad per-band attenuation level can be set to 5/10/15 dB. NB, NR, and Notch Tap NB 12 to enable

31、 DSP and I.F. noise blanking. Hold LEVEL to set DSP NB level (VFO A) and I.F. NB level (VFO B). Fully CCW is OFF in both cases. (Pg. 27.) Tap NR 12 to turn on noise reduction (saved per-mode). Hold ADJ to tailor noise reduction for the present band conditions (pg. 27). NTCH 12 turns on auto-notch in

32、 SSB mode, manual notch in others. MAN turns on manual notch in any mode, and is also used to adjust manual notch frequency (pg. 27). SPLIT, BSET, and SUB Hold SPLIT 13 to enter split mode (RX on VFO A, TX on VFO B). If VFOs A and B are on different frequencies in SPLIT mode, the Delta-F LED (f) wil

33、l turn on (pg. 13). Hold BSET 13 to adjust VFO B / sub RX settings independently of VFO A (pg. 39). Tap SUB 20 to turn on the sub receiver (pg. 39). VFO B controls its frequency. Hold DIV 20 to engage diversity mode (pg. 40), which can reduce signal fading. VFO B can be linked (slaved) to VFO A usin

34、g CONFIG:VFO LNK menu entry. Memories, Messages, and DVR To store a frequency memory, tap V M 14, then: tap M1-M4 15 to save a per-band quick memory; or tap 0-9 to save a general-purpose quick memory; or rotate VFO A to select from memories 0-99, then tap V M again to save. Tap M V to recall. (Pg. 1

35、6.) REC and M1-M4 15 are also used to record VFO A changes parameters. In general, CONFIG menu entries are used less often. Tapping DISP 8 within menus shows information about each entry on VFO B (pg. 55). Menu entries can be assigned to programmable switches PF1 , PF2 16 and M1-M4 15 (pg. 55). Thes

36、e switches can also be used to create custom SPLITs, etc. (macros, pg. 23). Other Features RX and TX EQ (MAIN menu) provide 8 bands of receive/transmit equalization (pg. 37). Tap AFX 18 to enable the selected audio effect (see CONFIG:AFX MD, pg. 55). Tap DISP 8 and use VFO B to show time, supply vol

37、tage, etc. on VFO B (pg. 38). The ALARM function (MAIN:ALARM menu entry) can be used to remind you about a contest, net, or QSO schedule, and can even turn the K3S on at alarm time (pg. 38). The KIO3B module provides a rich set of AF 34 and digital 31-33 I/O (pg. 17). 7 Introduction This comprehensi
