[Elecraft] [K3] Why do they still use 1/4 inch phone jacks?

[drewko]

I like the 1/4 jacks. They are more durable generally. It's no fun
having to tear the whole radio apart to replace a worn out
board-mounted jack. (Been there with the K2...)

You can get low-profile 1/4-to-1/8 adapters. I leave them plugged into
my K3's key and headphone jacks so there is zero wear.
