WOW! What a wonderful station accessory! This is way more than just an excellent SWR/Wattmeter! It also includes fully customizable, easy to understand software, modulation analysis, SWR graphing and much more! This is truly a "Swiss Army Knife" of station accessories. It is an excellent value and the sensors are calibrated and ready to go "right out of the box". My hat's off to WaveNode for offering such an incredible piece of gear. Also the customer service and communication are top notch! Thanks WaveNode, this is exactly what my station needed!!!
