The PX3 can display spans of up to 200 kHz
The Elecraft PX3 is a high-performance panadapter for the KX3 transceiver. It allows users to see the current band in real time, with spans of 2-200 kHz. This is a much wider range than what can normally be heard. The PX3's small size and weight make it ideal for travel or field use. It is also very tightly integrated with the KX3, making it very convenient to use.
The PX3 has a wide supply voltage range of 8-15 V and a low current drain of typically 140 mA @ 13.8 V. It includes a comprehensive manual and is available factory assembled or as a modular, no-soldering kit. The PX3 features 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 is also a full set of programmable switches to access often-used settings.
The PX3 adds a visual dimension to signal hunting, with fast, real-time spectrum and waterfall displays of band activity. It makes use of baseband RX I/Q signals from the KX3, which are sampled by an analog-to-digital converter (ADC) and then mathematically processed to create the spectral and waterfall displays. The PX3's ADC is very high performance, resulting in a low noise floor, and the supplied cables are short to minimize noise pickup.
The PX3 can be powered from an external source by connecting the power cables of the PX3 and KX3 together. This allows you to monitor battery voltage directly from the KX3. The PX3 can also be connected to a radio with I/Q signals available to see the RF spectrum. However, some features of the PX3 may not be available when connected in this way.
