[Elecraft] K3 PA bypass in receive

[Robert Tellefsen]

I've been studying the block diagram of the K3,
and have a question about the 100w PA block.

There is a bypass relay shown in in the PA I/O
block which would provide the receive path.
Is this really a relay or some bypass circuit?
I wouldn't be happy with a relay flapping away, trying
to follow keying.  Hate the clicking noise from
them.

Anybody know?
