Just announced today and posted for immediate sale on the Elecraft website!


High-performance companion panadapter for the Elecraft KX3 transceiver

Full-color waterfall and spectrum displays, with fast sweep and excellent sensitivity

Simple plug-and-play operation—no PC, soundcard, software drivers or setup required

Weighs just 13 oz (0.37 kg); enclosure size: 5.4 x 3.4 x 1.7” (13.7 x 8.6 x 4.3 cm)

Portable, High-Performance Panadapter

Our new PX3 Panadapter adds a visual dimension to
signal hunting, with fast, real-time spectrum and
waterfall displays of band activity. Its small size and
weight make it ideal for travel or field use.
The PX3 is fully integrated with the Elecraft KX3,
utilizing its serial control port and RX I/Q signals * .
The panadapter tracks the KX3’s VFO frequency and
filter settings via on-screen cursors. You can point and
click on signals by rotating and tapping the PX3’s
SELECT knob.

With its very wide dynamic range and frequency span
of up to 200 kHz, the PX3 offers better performance
than most PC sound cards. It’s also one of the most
sensitive panadapters available, detecting signals
down to the noise floor of the KX3. A PC or Mac can
still be connected to the KX3 (via the PX3) for use
with logging and control programs.

Advanced Features and Signal Processing
PX3 features include multi-pass signal averaging to
pull out weak signals, peak detection to show total
activity on the band, adjustable reference level, and
amplitude range scaling. There’s also a full set of
programmable switches to access often-used settings.
The PX3 has a wide supply voltage range (8-15 V)
and low current drain (typ. 140 mA @ 13.8 V). It
includes a comprehensive manual, and is available
factory assembled or as a modular, no-soldering kit.

Planned future features include:

CW/RTTY/PSK text display 

Use of the built-in USB port with a keyboard
or flash drive

SVGA monitor output option

* The PX3 uses the KX3’s baseband RX I/Q signals. It is not
compatible with the 8.2-MHz I.F. signal from the K3.
