K3 General Questions
S
Unequaled strong-signal receive performance; exceptional transmit
signal purity.
Built-in equivalent of Elecraft's PR6-10 low-noise amplifier (LNA)
for weak-signal work on 12, 10, and 6 m. Preamp 2 is part of the
KXV3B module (now included as a standard feature). The
KXV3B also provides RX antenna in/out jacks, transverter in/out
jacks, and a buffered IF output for use with our P3 panadapter.
Attenuation levels of 0, 5, 10, and 15 dB; selectable per-band.
In addition to the legacy RS232 port, the new USB port integrates
computer remote control and line-level audio. This eliminates the
need for a sound card or external converters and their associated
cables. Supports Windows, Linux and Apple platforms.
Lower loss on bands where matched antennas are used.
Stereo speaker outputs now have lower total harmonic distortion
(THD) for reduced listening fatigue.
High-accuracy CW transmit timing—even at high code speeds with
SPLIT, RIT, and XIT in use.
When used with the KBPF3A option, receiver covers 630 m (472
kHz), and 2200 m (137 kHz), tuning as low as 100 kHz. Transmit
output of 0.5-1.0 mW on 630 m (for use with an external amplifier).
New LCD bezel; soft-touch VFO A knob with improved grip.
