I'm including a picture of this with a 9V battery installed to demonstrate how and where to install the battery. However, I'm not including the battery, since it could come loose and bounce around inside during shipping. When installing the battery, be sure to have it shoved off to the left side of the cover as I did to prevent the air variable capacitor on the right from contacting it when it is rotated. This is from an estate. I haven't tested it, since I don't have adapters to connect my KX3 to it, and I haven't the foggiest idea how to use it. So, am asking only $30.00 + shipping to USA addresses only. Sold AS-IS. No return due to parts swappers. My email address in my QRZ profile page works.
