Finally got the radio keys today then ran the SN with Becker got the code and the system came right up. Antenna when it extended was filthy with dried gunk crusted all over it at the mast joints and looked like it hadn't been turned on and extended in quite a while till today. I took a cloth soaked with some real military grade CLR I had on hand and cleaned the mast well. Anything that is needed as a lube on these and any maintenance that may need to be done with the rest of the unit?
