The K3like its

9、 predecessor, the K2reflects our desire to go beyond what other high-performance transceivers have offered. It isnt just a home-station rig; at about 8 to 9 pounds, it can accompany you wherever you go, whether its out to your back porch or halfway around the world. And its the only rig in its class

10、 that you can build yourself. Above all, we want the K3 to be ready for any operating situation you encounter, and to be more enjoyable to use than any transceiver youve ever owned. In addition to this manual, youll find much more information on the K3 on our web site, including operating tips, answ

11、ers to frequently asked questions, and information on firmware upgrades and accessories. 73, Wayne, N6KR Eric, WA6HHQ Key to Symbols and Text Styles Important read carefully Operating tip LSB .

MAIN:VOX GN Typical MAIN menu entry

13、 CONFIG:KAT3 Typical CONFIG menu entry 4 Quick-Start Guide To get started using your K3 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 example, 1 refers t

14、o 1, the mic jack. Later sections provide greater detail on all aspects of K3 operation. The first thing you need to know about the K3 is that most switches have two functions. Tap (press briefly) to activate the function labeled on a switch. Hold to activate the function labeled below the switch. I

15、n the text, tap functions are shown like this: 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 entries, while rotating VFO A 22 changes their paramet

16、ers. Tap MENU again to exit the menu. 5 Connections Connect a power supply to the DC input jack 26 (see Specifications, pg. 8). On the K3/100, a circuit breaker is provided on the fan panel for the 100-W stage 38. You can power an accessory device from the switched DC output jack 39 (0.5 A max). Con

17、nect an antenna to ANT1 29. With an ATU (pg. 22), you can also use ANT2 28. AUX RF 27 is for the sub receiver; see pg. 17. ANT3 30 is used with the internal 2-m module (K144XV). With a KXV3, you can connect an RX antenna to RX ANT IN 34. The Basics Press POWER 5 to turn on the K3. If there are any e

18、rror indications, refer to pg. 68. 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 tap MODE 6 to select the mode. Set the AF gain using AF 2.

19、 Set RF to max. SUB controls are discussed on pg. 37. 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. 36). CMP / PWR is one of four multifunction controls 24. Each has two primary functions, indicat

20、ed 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 SHIFT / LOCUT and HICUT / WIDTH controls 23

21、 to adjust the filter passband. Crystal filters FL1-FL5 are automatically selected as you change the bandwidth. Tap either knob to alternate between shift/width and hicut/locut. Hold SHIFT / LOCUT to NORMalize the bandwidth (e.g., 400 Hz CW, 2.8 kHz SSB). Hold HICUT / WIDTH to alternate between two

22、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 the desired compression. Then return to SWR / PWR (pg. 28). Optiona

23、l: 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. 29; TX EQ, pg. 35; MIC SEL, pg. 52; SSB/AM/FM, pg. 28. CW Mode 36

24、SPEED 25 sets the CW keyer speed. Hold this knob to set semi-break-in DELAY. Hold QSK 7 to select full QSK (pg. 30.). Hold VOX 7 to select hit-the-key CW. Hold PITCH 18 to set sidetone pitch. Hold CMP / PWR to set sidetone MON level. Tap CWT 18 for tuning aid 9 (pg. 34). With CWT on, SPOT auto-spots

25、 (pg. 30). To select CW text decode/display mode, hold TEXT DEC 18; rotate VFO B (pg. 30). CW keying is converted to DATA in FSK D and PSK D modes (below and pg. 34). Hold DUAL PB 13 to turn on audio peaking (APF) or dual-passband filtering (pg. 30). Data Modes 31 Tap MODE 6 until you see the DATA i

26、con turn on (see Data Modes, pg. 31). Hold DATA MD 18. Use VFO B to select from: DATA A (PSK31 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. 16.) REC and M1-M4 15 are also used to record VFO A chan

27、ges parameters. In general, CONFIG menu entries are used less often. Tapping DISP 8 within menus shows information about each entry on VFO B (pg 52). Menu entries can be assigned to programmable switches PF1 , PF2 16 and M1-M4 15 (pg 52). These switches can also execute often-used macros like “SPLIT

28、, AB, move VFO B up 5,” with a single tap or hold. See the K3 Programmers Reference for examples. Other Features RX and TX EQ (MAIN menu) provide 8 bands of receive/transmit equalization (pg. 35). Tap AFX 18 to enable the selected audio effect (see CONFIG:AFX MD, pg. 52). Tap DISP 8 and use VFO B to

29、 show time, supply voltage, etc. on VFO B (pg. 36). 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 K3 on at alarm time (pg. 36). The KIO3 module provides a rich set of AF 33 and digital 32 I/O (pg. 17). 7 Introduction
