MFJ-939Y Auto Tuner Works well. I used it very lightly, maybe a few times at most. I bought it used from another QRZ member about a year go. Includes the MFJ cable for Yaesu interface. Tunes automatically with many features when used with compatible Yaesu radios. Can be configuring for other brands, Icom, etc. but you have to purchase the correct interface cable for the radio. Does NOT include power. If you are using the interface cable, Yaesu radios will power the tuner via the cable. No additional power cable needed. $95 Shipped in CONUS. Other locations please inquire.
