The Ham Shack computer has become the amateur radio operator’s favorite accessory for logging, DX spotting, digital model operation, and even antenna modeling and circuit design. Now you can have a computer accessory that functions as a complete Station Monitoring System for your unique installation. WaveNode WN-1 supplies a four-channel digital RF wattmeter, SWR meter, and a power supply monitor, and even provides additional analog inputs for your computer that you can customize for your applications.

With WaveNode and the help your computer, you can optimize the performance of your ham station using one state-of-the-art accessory and up to four remote sensors. WaveNode, founded in 2003 by Amateur radio operators, makes the WaveNode WN-1, a tool which allows you to customize and integrate the data you need to monitor your amateur radio station and obtain peak performance from all the components.

The WaveNode WN-1 provides RF measurement on four remote Coax sensors simultaneously, and can provide amplifier gain, tuner loss, and other information on your screen as you operate. The WaveNode sensor selection provides 0.025--8KW measurement from 1.6-470 MHz, all on a single display. The remote in-line sensors come in four types: A 2KW HF sensor for 160-6 meters, an 8 KW HF sensor, a UHF-1 sensor t to cover 140-470 MHz and a QRP sensor, which provides accurate Power and SWR measurement between 20 milliwatts and 60 watts.
The operator can mix and match these sensors to provide digital measurement on all their favorite bands. Two terminals in the rear provide power supply voltage and current monitoring on the screen to complement other data readouts.

SWR, forward and reflected power, power supply and other measurements are presented in a clear graphical display on your computer screen and calibrated with digital accuracy. You can select your choice of graphs, power histograms, SWR plotting and other functions to monitor the performance of your station equipment, including antennas, tuners, radios and power supplies. For instance, a real-time plot of different instantaneous power levels provides information about amplifier linearity and gain. The WN-1 continuously updates this information. Tuner, amplifier, and antenna performance are visible with just a glance at the computer monitor.

An SWR monitor and relay is a standard feature on the WaveNode WN-1 to protect the radio or amplifier if the SWR is excessive. Audio-announcing of power and SWR is available as a single key stroke, convenient for any operator and a valuable feature for sight-impaired hams. Personalize your computer screen with custom configurations of the meter scale, meter titles and the appearance of the screen. A click of the mouse adjusts peak hold times, averaging time, and SWR protection.

Every operator wants the opportunity to customize a piece of gear so they can experiment. The WN-1 has four additional analog inputs that can be used to monitor temperature sensors, power supplies, or any other voltage. Three logical outputs are provided that can be toggled ON/OFF on the screen to allow antenna switching, linear keying, or other functions. The WN-1 makes it easy to build your own computer interface; the inputs and outputs are done for you.

Now for the technical details: accuracy is +/- 10% with resolution <0.5 watt. In-line sensors give greater than 30 db directivity, which provides accurate SWR indication to below 1.05:1 SWR is provided down to two watts of forward power. The sensors are factory calibrated, and more sensors can be added at any time. Best of all, ALL software is in the computer. Software upgrades are provided FREE on the website at www.wavenode.com.

The WN-1 operates with any Windows Operating System. Software is provided on a CD-ROM for easy installation. A comprehensive "Help" file is available with a mouse click, but the system is easy enough to use without reading a single instruction. WaveNode WN-1 is the amateur radio accessory that enables you to put the computing power of your PC to work in your amateur radio installation.
