Ken, N4SO, as a dummy load project, you suggested:

I've built this load and it works great for me. Another possibility is =
a
project that was published in the NJ-QRP's QRP Homebrewer (Issue #2).

The "Common Cents" QRP Dummy Load, by Dave Ottenberg, WA2DJN
Dave WA2DJN is a formidable sidekick to gadgeteer W2GUM and they teamed=
 up
to create a very handy piece of equipment that everyone needs in the QR=
P
workbench ... a dummy load. =A0 But this is no ordinary dummy load, as =
it's
made by sandwiching four carbon resistors between two pennies, soldered=

right on top your favorite antenna connector. =A0 So all you need to do=
 is
connect this little 1" dummy load connector to your rig ad your as safe=
 as
can be.

Instead of four 200-ohm resistors, I used six 300-ohm resistors at 2W e=

to approach full power for my barefoot K2. And instead of pennies, I us=
ed
little discs of double-sided PCB material. Easier to drill through, at
least for me. Just note that the wire protruding from the center pin
through the bottom disc must be insulated from the shell by a little bi=
t of
shrink wrap. That bottom disc (or penny, your choice) is soldered to th=
e
shell.
