Elecraft K3 Owner's Manual - Manual (Page 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).
• Connect 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 P O WE R {5} to turn on the K3. If there are any error indications, refer to pg. 68.
• T A P and H O L D 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 B A N D {7} to select a band, and tap M O D E {6} to select the mode. Set
the AF gain using AF {2}. 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, 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, MON itor level. Tap again to restore the primary function.
Filter
Controls
• Rotate the SHIFT / LOCUT and HICUT / WIDTH controls {23} 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 NOR M alize the bandwidth (e.g., 400 Hz CW, 2.8 kHz SSB).
• Hold HICUT / WIDTH to alternate between two filter setups, I and II (per-mode).
• Tap X F IL {13} to select crystal filters manually; this also removes any passband shift.
Voice Modes
{1}
• Hold M E T E R {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).
• Optional: Hold T E S T {6} for TX TEST mode; allows off-air TX adjustments (pg. 13).
• Hold CMP / PWR {24} to set speech MON itor level; tap to return to CMP / PWR .
• Hold V O X {7} to select PTT or VOX . Hold SPEED / MIC to set VOX DEL AY .
• Details: VOX, pg. 29; TX EQ, pg. 35; MIC SEL, pg. 52; SSB/AM/FM, pg. 28.
CW Mode
{36}
• SPEED {25} sets the CW keyer speed. Hold this knob to set semi-break-in DEL AY .
Hold Q S K {7} to select full QSK (pg. 30.). Hold VOX {7} to select hit-the-key CW.
• Hold P IT C H {18} to set sidetone pitch. Hold CMP / PWR to set sidetone MON level.
• Tap C WT {18} for tuning aid {9} (pg. 34). With CWT on, S P O T auto-spots (pg. 30).
• To select CW text decode/display mode, hold T E X T D E C {18}; rotate VFO B (pg. 30).
• CW keying is converted to DATA in FSK D and PSK D modes (below and pg. 34).
• Hold D U A L P B {13} to turn on audio peaking (APF) or dual-passband filtering (pg. 30).
Data Modes
{31}
• Tap M O D E {6} until you see the DAT A icon turn on (see Data Modes, pg. 31).
• Hold D A T A M D {18}. Use VFO B to select from: DAT A A (PSK31 & other
soundcard-based modes), AFS K A (soundcard-based RTTY), FSK D (RTTY via data
input or keyer), or PSK D (PSK via data input or keyer). VFO A selects data baud rate
for internal encoder/decoder, if applicable. D U A L P B turns on RTTY filter (DTF, pg. 32).
• Hold P IT C H {18} to select mark tone and shift (for encoder/decoder and RTTY filter).
• Hold T E X T D E C {18} to set up text decode. C WT shows tuning aid (pg. 34).
