I have had this for several years. When I received it, it had recently been gone thru for function check and update at depot level. It still had the paperwork with it. That was back in the early 90's. I also had 1 military issue battery for it, which has since gone dead. This is/was the standard military aircrew survival radio, 2 channels, with an extra 3d channel for emergency beacon. I can probably come up with more batteries for it that might be in storage somewhere with the radio. Email if interested, asking price is $225.00 shipped priority mail w/insurance and delivery confirmation. Thanks for looking....Tommy.
