The New Hotness

  • Ending an Antenna Rattle

    This Comet HT-224 antenna fits on my Kenwood TH-F6A radio, but the connector fitting is just slightly too long / short / something: it moves just a little bit, even with the nut firmly tightened.

    This isn’t a real fix, but it pretty much eliminates the rattle: a rubber O-ring between the nut and the antenna…

    The ring lasts for a few years, then cracks and falls off. My O-ring stash has what could possibly be a lifetime supply.

    There’s a wrap of tape around the label, just for neatness.
