[Elecraft] K3/P3 DOA

[Bill Conkling]

Hello, friends....

First I'd like to thank all that responded with possible solutions to my
friends dilemma.

We did verify the orientation of the RF board in the P3.

We did verify the resistor change was good.

We weren't too successful in listing to the IF OUT on the sub-rec.

Mark came by my shack this afternoon, and brought his radio/P3.   First we
hooked his P3 to my radio and it showed signals like it should.  I was
dismayed as I had hoped it would be a simple P3 problem, easily swapped out.

Then we began opening up the K3 hoping to find something amiss that we could
fix easily.  When we got down to the KX3Va board, and compared it's
installation to what the book called for, there it was.  It appears that the
original builder had inserted the TMP plug into the "OUT" socket, not the
"IN" socket.  We plugged the TMP cable into the correct socket, and
re-assembled the K3.  It worked as it was supposed to.  Hooray!  It was
fixed, Mark is a happy Elecraft owner.

Again, thanks to all who tried to help.

Friends, 

 

My good friend and elmer Mark (n1lo) recently purchased a pre-loved K3 and
treated himself to a P3-K for Christmas.  I visited him yesterday, and
watched as he assembled his new 'toy'.  All went pretty well, until we
hooked it up.  It all seems to work, except, there is no signal showing on
the P3 screen.  All the markings are there, display seems to be working, but
no signal.  Adjusting the "REF LVL" brings up 'noise' but removing the BNC
cable does not change the display.  

 

Tried connecting to the IF OUT connector and turning the switch 'ON' made no
difference.  

 

Tried another BNC cable, same result.  

 

Opened the P3 and checked the TMP cable but it was firmly connected at both
ends.  No change.

 

He has emailed support for assistance but it is New Years and may not hear
anything immediately as expected with the holiday and all.

 

So, it the mean time, anyone here have an idea that we haven't thought of?

 

He did the mod to the radio to increase the output, but that looks good.
