K3, I broke it. Headed for the schematics

OK, Magic people, I broke it. First responses are the right ones. I
installed the 2m internal module (physically) and the FM Filter. Audio gone
even before utility ran to configure filters ("all bands").

No audio through speaker or headset (front connections) except white noise,
no signals. I see the signals on my P3 just as they should be. Normal
amplitude, etc. The only connections to the 2 meter module is power, other
cables not connected.

Any ideas where the connector is that I somehow disconnected?

Headed for the schematics.

Filters were #1 was 2.7, #2 was 1.8, #3 was blank, #4 was 500, #5 was 250
Filters now #1 is 13.0, #2 is 2.7, #3 is 1.8, #4 is 500, #5 is 250
In config - just moved settings for #2 to #3 and #1 to #2 and added #1 as
13.0 and set for FM but NOT installed.

Thanks es 73, de Jim KG0KP

Jim,

Technically, if you hear "white noise", you have audio. Sorry to be so
"picky", but it is quite important in troubleshooting to use exact
language so we all understand each other. From your statements I would
rather have seen you say that you have audio, but do not hear any
signals AND that you see signals on the P3.
That places the problem between the IF output and the input to the DSP -
in other words the filter section of the receiver.
Check your filter configuration again, and check the physical
installation of the filters - backwards filters do not work right.

Fixed it. reinstalling the second receiver pulled out a cable to a front
panel board and the end was under the receiver so I couldn't see it. Once
it was removed, it was obvious. Thanks guys.

Counting in either direction to find where to install a filter sounds like
an approach that is very prone to errors. I don't have a K3 so I can't check
its innards, but wouldn't it make more sense to use some sort of (silk
screen?) labelling where the filters are placed with labels like "Filter 1",
"Filter 2", or just "F1", "F2"? The information for installing a filter can
then use the labels when indicating where it needs to be (or can be) placed.

The locations are labelled. Look at page 5, figure 1 of the K3 assembly
manual. The filter locations are printed on the top of the white filter
outlines.

Re: K3, I broke it. Headed for the schematics

Ron,

Maybe the best answer to this problem is for the first step after
removing the top cover is to turn the K3 with the back toward you - then
the filters align left to right.
The labels may be upside down, but the order would be from left to right.

Re: K3, I broke it. Headed for the schematics

Anyone with any knowledge of high school math will see numbers on a number
line increasing as you go left to right. I don't think that is cultural in
the language of mathematics.

As for putting filters in the wrong spot: RTFM. At some point it should
be the builder's responsibility. I think Elecraft has done their part in
this area.

I had the same problem when I installed my KRX3. The offset for a the 2.7hz filter was .9 and I entered 9. This put the filter out of the sinal path. Check for the dot.
