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)
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
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.
Features and Signal Processing
PX3 features include CW/RTTY/PSK text display, 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.
New Features include:
CW/RTTY/PSK text display
Tracking and Fixed Tune display modes
DSP Noise Blanker for display
* 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.
