How many relays in a K3?

Looking at the schematics, there seem to be a ton.

Guess electromechanical devices are not dead yet.

We use relays where we need high isolation and essentially zero loss, such as band-pass and low-pass filters. We use PIN diodes or CMOS switches where they won't have any negative impact. In particular, we use heavily biased PIN diodes in all of our transceivers' T/R switches.
