New K3 build, LOW LOW sensitivity.

Everything in the manual checked out ok. I am at the stage before putting in the 100 watt PA. Just checking things out. I have the IF Out board, but that's about it. No ATU. Setup filters, etc. But, I have only about S1 on the S Meter, and can only weakly hear the strongest of signals. Even WWV is poor. This is on a known good antenna/coax.

Anyhow, just wondering what to check. I haven't set the REF OSC yet because I can't get a strong enough signal to do it.

Ideas? I thought I was sailing along smoothly.

Thanks,

joe

Joe,

Do you have a KXV3 module installed? You may be switched to the RX antenna.

Are you certain you have the correct antenna selected? Been there, done
that. :-)

Ok, checked the RX ANT switch. It was not on. I did connect an antenna to the RX ANT jack and switched to it, but no difference.

Not sure what is wrong where. In any case, there is very little sensitivity in the K3 at this point.

Don't know what to check. I have gone back through the best I can... seems everything was done correctly.

Very careful about ESD.

Re: New K3 build, LOW LOW sensitivity.

Check all the coaxial cables that plug into the boards and front panel.
Make sure they go the right places. I would also check the way you have
decided to handle the coax going to the coax chassis connector SO239.
There are a couple of ways to do this depending on your options.

Re: New K3 build, LOW LOW sensitivity.

I had something similar, but I was most likely using the wrong antenna.
I heard nothing (the bands were probably dead, and I couldn't even hear
the local AM stations. I checked the weird coax cables, loaded the
latest beta firmware, and then everything started to work. I may have
even worked 3G0ZC (though he first miscopied my call as K7EMS instead of
K7EMI so I'm not all that certain).
