This item is UNTESTED, but it appears to be in excellent, unused, vintage condition. It’s from my grandfather’s estate, and I don’t think he ever actually used it. The YAESU YS-60 Ham Radio SWR & POWER METER is a high-quality wattmeter designed for ham radio enthusiasts. Made in Japan by Yaesu, this meter is compatible with Yaesu brand transceivers and is capable of measuring both power and SWR within the 1.6-60Mhz frequency range. With connectivity options for VHF bands and the ability to fit a variety of ham radio transceivers, this power meter is a valuable tool for optimizing your radio communication setup. The untested nature of this product adds an element of risk, but the Yaesu brand reputation ensures reliability and performance.
