Oak Hills Research sells a kit with a female BNC and a punched plate sized to fit in place of a SO-239 for $5.00 each or two for $7.50. I have them on both of my K3s and quite a few other places in the shack. The ones that haven't been replaced wear adapters to BNC, all my cables are BNC... That reminds me, I've got to yoder a few more...
