Vin,
Congratulations on completing your KX1 your fun is just beginning. Your
audio will naturally be higher on 40M, at least mine is. Low audio output is
a common subject on this net for the KX1. I suspect your unit is fine.
Sensitive earphones are a necessity with the KX1, check your specifications.
I use 94-dB sensitivity headphones which are adequate but on the low side
for a KX1. There are a lot of low cost headsets/earbuds with sensitivity
above 110-dB/Mw.
On 40M with filter set to wide and connected to a full sized dipole the band
noise is too loud with full audio gain. With narrowest filter settings I
tend to run the audio gain full on but no desire for more.

Subject: [Elecraft] KX1 Receiver alignment - further information
OK
I managed to whittle a plastic tuning wand to the correct shape in order to
adjust the 2 tuning capacitors for 20M and the 1 for 40M.
The situation I mentioned about touching the board and having the signal
come way, way up is only happening when I transmit my K1-4 into the DL1 in
the shack. So the increase in gain may be that the RF is in the shack (even
though it is only 100 mW into a dummy load), and when I touch the board
(especially near L7), I am capacitivlely coupling a high amount of RF into
the KX1. If I simply listen to 40M or 20M, on an antenna and touch the
board, nothing happens. But I am still slightly troubled by the fact that
signals on the KX1 just aren't as loud and/or strong as on any other radio
in my shack with the same antenna.
I have done numerous checks for cold/non-existent solder joints. Any ideas
what may be wrong, if anything?
Thanks again.

Hi there, again.
I just finished Alignment and Test Part II. For the most part, things seem
OK, but I have one or two concerns.
As a signal source, I used my K1-4 at 100mW into my Elecraft DL-1. Now out
of all my alignment tools, none of the non-ferrous type would fit in the
alignment hole through the board. So I took a metallic screwdriver and
electrical taped the entire shaft except for the tip. Despite the
insulation, the metal in influencing the alignment, of course, so I am
trying to align slightly, pull away and see what happens. If I touch the
board near the cap, the gains comes WAY, WAY up, but only for the duration
of the touch. Also, I notice that while listening to receive, I am hearing
signals, but not nearly as strong as I hear them on any other receiver in
the shack on the same antenna.
I think I know what you are going to tell me. Get a non-ferrous alignment
tool, right?
This may simply be because the alignment is not quite correct, but I also
notice that even with the volume up full, the background hiss isn't really
that loud
