![]() ![]() ![]() Q: Why is the PX3 always placed to the left of the KX3 in example photos?Ī: This minimizes physical cable length between the two units, keeps them spaced close together, and keeps the PX3 away from the KX3s antenna jack, which may be important if an end-fed wire antenna is being used. This tells you at a glance where signals have recently been, even if theyre not transmitting at the moment. When the reference level (REF) is adjusted so that the bands noise floor is right at the bottom of the spectral display, the waterfall will be mostly dark, with signals appearing as light areas. Each type of signal creates a unique signature (with a little practice you can even copy Morse code right on the waterfall display, in the form of colored dots and dashes). Signals pourdown the waterfall, in time, with their color showing how strong they are. (For additional information and illustrated examples, please refer to the PX3 owners manual, which can be downloaded from our PX3 web page.) Q: What is a waterfall display?Ī: The PX3 can show a waterfalldisplay, which shows a running history of band activity. Another common use is to observe the nature of a split-pileup, using the PX3 to see who a DX station is working, then set your own transmitter to about the same frequency. This is a great way to find DX stations, and you can often tell what the stations operating mode is once you become familiar with their various patterns. In this case you can use the PX3s marker (QSY) knob to point at a signal of interest, then push (tap) on the knob to move the KX3 to that frequency. The most basic use of a panadapter is to simply locate signals sometimes a band will seem dead on your receiver, while the panadapter will show one or more stations. This allows you to see signals on a given band, over a much wider range than you can normally only hear them. It includes a comprehensive manual, and is available factory assembled or as a modular, no-soldering kit.Ī: A panadapter, also known as a spectrum scope, is a device with a 2-dimensional display showing frequency on its X-axis and signal amplitude on its Y-axis. The PX3 has a wide supply voltage range (8-15 V) and low current drain (typ. There’s also a full set of programmable switches to access often-used settings. 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. A PC or Mac can still be connected to the KX3 (via the PX3) for use with logging and control programs. It’s also one of the most sensitive panadapters available, detecting signals down to the noise floor of the KX3. With its very wide dynamic range and frequency span of up to 200 kHz, the PX3 offers better performance than most PC sound cards. You can point and click on signals by rotating and tapping the PX3’s SELECT knob. The panadapter tracks the KX3’s VFO frequency and filter settings via on-screen cursors. The PX3 is fully integrated with the Elecraft KX3, utilizing its serial control port and RX I/Q signals *. Its small size and weight make it ideal for travel or field use. The PX3 Panadapter adds a visual dimension to signal hunting, with fast, real-time spectrum and waterfall displays of band activity.
