[K2] Ground connection?

[bdenley]

There is a hole in the back of my K2 marked 'GND'.  Looking for a suitable
ground connection to my K2 I wondered if this 'hole' gets filled by an
option.  What are other users using for a K2 ground connection?

  Brian,

If you have the KAT2 or the KPA100 option installed, there will be a
binding post for the ground connection.  If you have the basic K2, and
you wish to have a ground connection, put a 5 way binding post on the
mounting hole labeled "ground" and connect it to your station ground point.

In actual practice, you may not need a ground connection for the K2.  A
ground connection for any transceiver is to connect the chassis to other
gear in the hamshack, and to connect to the "ground" for your antenna
system.

If your antenna system presents a good 50 ohm match to the K2, a ground
is not required - just feed the antenna.

The grounding of every "box" in the hamshack should be more for reducing
"box" to "box" potential differences than for eliminating any other
"problems".  If you have only a K2 and an antenna, there is no need for
a "ground" connection.

Brian...

The hole is threaded to accept a corresponding bolt with an enlarged end
for finger tightening. The idea is for the threaded bolt to hold a
ground wire/strap to the K2. I found this arrangement difficult to use
in my particular setup. So, I inserted a bolt from the inside out and
then used a wing nut on the outside to hold my grounding strap. This has
worked for me. YMMV.
