[Kenwood] Bad SM-220 Shaft Couplers

[Corey Sukalich]

Curious if there is a suitable replacement for the switch shaft couplers (Function, RF Att.) on the SM-220.  One of mine has cracked, and cross-referencing I only found a single source wanting $18 each for the nylon parts!  Ouch.  Guessing there has to be a better way.

Can anyone confirm if these really need to be isolated?  It looks like there are flex couplers available on eBay for much cheaper but so far I haven’t found one of the same dimensions.

I know some have replaced similar parts on other Kenwood radios with aftermarket solutions.  Thanks!
