[Elecraft] K3 Key Out

[Don Rasmussen]

The main benefit would be to other transceivers you
may have, like my OMNI VI+, now I don't need to think
which of my rigs are okay for the amp. It's great to
know the K3 device is diode protected - K3 - what
else? !!!


>>>The Elecraft K3 uses an IRF1630 HEXFET Power
MOSFET, rated for 200V with an ON Resistance of .4 Ohm
in a TO-220 Package. Don't see much of a gain by using
the external device.....

The Keying Transistor used in the Harbach Soft Key
uses an IRF610 HEXFET
Power MOSFET, rated for 200V with an ON Resistance of
1.5 Ohm in a TO-220
Package.

The Elecraft K3 uses an IRF1630 HEXFET Power MOSFET,
rated for 200V with an
ON Resistance of .4 Ohm in a TO-220 Package.
