ELECRAFT K3S - Connections; Filter Controls; Voice Modes; CW Mode

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 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 POWER {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 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 {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, MONitor level. Tap again to restore the primary function.
Filter Controls
• Rotate the SHIFT / 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 Hz CW, 2.8 kHz SSB).
• Hold HI CUT / WIDTH to alternate between two filter setups, I and II (per-mode).
• Tap X FIL {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. 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. 31; 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.
• Tap 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 filtering (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 keyer). 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).
