    s/rf meter sticking

    Any hints, tips or ideas on freeing up a 30+ year old s meter? All my normal dirty tricks aren't helping this one. Where would I find one for an 80s model president Madison? I managed to free up the swr/ modulation meter but the other one is stuck on 9 wether the radio is on or not. thanks 73s

    There's anumber of things you can check. First check the air gap between the armature coil and the magnets, most suck needles are caused but dirt and dust getting the gap. The other is the be sure the needle doesn't touch the inside face of the plastic cover.

    Do yourself a favor and "Get A New Meter" they are cheap enough. You can try to loosen up but in my experience may only buy yourself a week or 2 before sticks again.
