Excellent advice Don. I bought a 100w dummy load kit from OHR. It's
called the RFL-100 and it's about $40, comes in a very nice cabinet, and
takes less than an hour to build. It has come in handy more times than
I can count.

Oak Hills has some good goods.

Tony,
"Scolding time" :-)
One thing that I believe should be in every ham's shack is a dummy
load capable of handling the maximum power that your station can
develop. Ridge Equipment has a 50 ohm 75 watt dummy load good up to
1.5GHz for $11.95, but you will need an adapter for UHF connectors so
that is an additional $5. See
https://www.ridgeequipment.com/store/dummyloads.html.
If ever you run into a problem, the first check is to see what happens
when you transmit into a dummy load. That removes many variables -
like RFI problems and antenna problems. It is the first check I
recommend. If the rig works into the dummy load, you need to look for
the problem somewhere other than the rig.
I have had rigs sent to me for "repair" only to find that there is
nothing wrong. The resulting repair charge is greater than the cost
of a good dummy load.
If you look for one at a hamfest, take your ohmmeter along to check if
it is still a 50 ohm load - some are burned out from excessive power.

Well, now I downloaded the new firmware, only to discover that I have
to do
the 50W calibration. I have a 5W dummy load, but no 50W. The 5W
calibration
went okay. So do I have to get a 50W dummy load before I can use the K3
again? Or should I back down to the previous firmware? Or what?
