[Elecraft] K3 Key Out line

[Phil Hystad]

I noticed from the documentation that the K3 Key out line can handle up to 200 VDC and 5 amps.  I assume this means that when the key out is closed that it can handle 5 amps of current.

So, I am curious, what kind of switch mechanism is used for TR switching.  Is this an actual relay or is it some kind of transistor switch.  I am guessing transistor based switch but this is where I started wondering about the 200 VDC and 5 amp capability thing.

Or, am I totally off base.  I am willing to be off base without shame because I really do not know a lot of details of how these things are actually done.

Oh, two more minor decisions on configuration to make and then I order my K3, probably just after Christmas sometime.
