I think the answer as to why an owner would want a schematic is given to us by
the slogan, Elecraft - Hands on Ham RadioSimple as that.

A simple enough request - yet such nasty and unhelpful responses. Are
they really necessary?
And, yes.. schematics should be available for ALL ham equipment. In
fact, they should accompany all ham equipment when purchased.

Seems like you may have a bad connection between the RF board and the tuner, or
between the tuner and the BNC connector. I'd investigate that first. If no
luck, try removing the tuner altogether and see what happens into a dummy load.
If you contact Ekecraft support, they can help you isolate
I had a similar problem with my KX3. My problem included no

antenna BNC connector had been pushed in just a little. The
clearances are quite tight there, and the antenna BNC was
shorted. I bent the case back into shape, removed the
I've been following this discussion with interest. I've used the NCC-1 with

My best success with noise cancellation has been on the higher bands

Phil and all,
There are two types of dummy loads - one is simply to provide a load to
your transceiver or amplifier for a quick sanity check that the
transceiver or amp is providing output and is capable of transmitting a
signal.
The other type of dummy load is one used for calibration

Mark,
You must first tap DISPLAY to get into the DSP menu.
Without being in a DSP menu, a hold of STORE+RCL normally puts you into
a Direct Frequency Entry state which will display the dashes that you see.

Your 20-watt dummy load will work with the automated procedure, and it is
the best one because if the SWR is over some threshold you'll get a SWR
too high, calibration failed message.
The 20-watt load is very unlikely to overheat; my 10-watt load did not

Has anybody asked Elecraft support for a schematic?
I was about to ask the same thing. This thread is just plain silly. When I got
my KPA, I simply called them up and asked for one. They obliged. So simple. I
do happen to agree that it should have been provided in the package though.

Phil, why don't you hold it on 17 meters this weekend? A number of the
SOTA crowd that frequent the SSB freq's from summits went to 17 and 12
meters today. SFI is pretty high relative to what it has been, 17 might
be a good analog for 20.

Apparently there is some misunderstanding regarding my comment (Or

was NOT responding to the original poster. I was responding to the
second commenter, who said that he needed a schematic because his NEW
