Hi all, I am looking for the RF output power knob for a Magnum 257HP. It's the small inner one on the top right of the rig. Kind of a rubbery finish to it, mine split in the middle and then I lost the pieces! Anyone have a source?

These came from a ProStar400 or rpsy 485 or the like. Not really rubbery, but not really hard.
The inner knob looks to be spline, the outer knob looks to fit over split type shaft.
Been a long time since I owned one, don't remember the configuration.
You can PM if you're interested.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
